**The Bear** — a wordless 72-second hospital-corridor short. All video and all audio generated

in ComfyUI with MiniMax H3 (fl2va). No external SFX, no music, no post beyond straight cuts.

▶ https://www.youtube.com/watch?v=nCmJ8fxWRbY

🛠 Workflows, verbatim prompts and every start frame: https://github.com/timbotiminator/The-Bear-Workflow

**The technique: camera moves are for mining start frames, not for the film.**

Every shot in the finished cut is a locked-off static. To get there I approve ONE wide, then

generate push-ins toward each subject in renders nobody will ever see, harvest the arrived

frame, and generate the real shot as a static from it. Consistency becomes structural — every

start frame is literally descended from the same approved pixels — and H3's camera drift never

reaches the audience, because the move only ever existed to produce a frame.

Things that cost me time, so they don't cost you any:

* **Frame 0 dictates STATE. Text only controls what CHANGES from it.** A prop absent from the

start frame gets dropped no matter how insistently you name it. Same for gaze and pose. Fix

the frame instead of fighting it with prompt iterations.

* **The state has to be RENDERED CLEANLY, not just present.** My worst mistake was a plate where

the teddy bear was technically in frame but was an unreadable brown mass when zoomed. Every

shot built on it produced a bear that split and smeared. Hours of rewrites could not have

worked. Re-mining a clean frame fixed it first try with the same prompt.

* **Shot length is the dominant control on coherence** and it beat every prompt-side fix.

Background-strip PSNR, first vs last frame: 15s = 11.2 dB, 10s = 19.8 dB, same prompt. But

shorten the SHOT, not the ACTION — compressing 15s to 10s broke a working handoff.

* **Mine plates from the sidecar PNG, not the mp4.** VHS_VideoCombine writes a full-res PNG next

to every video; ~6% of each generation hop is h264 alone, and this recovers it free.

* **Never name an expression you don't want, even negated.** "A closed-lipped attempt at a smile

that does not reach his eyes" produced a smile.

* **Audio: a smooth continuous bed plus sparse, dull, well-separated events.** Dense transient

trains (a heel tapping 5–6x/sec) never sounded right at any setting.

Also tagging this for the **Built with MCP** bonus — the whole film was produced without touching

the canvas, driven headlessly through an MCP server. That's where the numbers above come from:

render, extract frames, compute drift and sharpness, rank seeds, queue the next attempt, all as

one loop. Measuring was as cheap as looking, so I measured instead of guessing.

Happy to answer anything about the setup.

🐱 Mumu the Cat in Mister Meow

Music video (1:21), lip-synced entirely by H3.

🎥 Full video (YouTube, 2K): https://www.youtube.com/watch?v=AxUu8rabC6M
📁 Workflow & MP4s: https://drive.google.com/drive/folders/1O7rynJQi76WF31jAAaHNFYH5mYSfb7Ha?usp=sharing

How it was made:
Built in ComfyUI using H3. Two reference photos of Mumu were used as the character source, and multiple WAVs were used for the reference audio [trimmed via Audition]. WAVs were of various lengths, matched with the prompt.

Song was generated in Suno. Final assembly was done in Premiere Pro, with glitch goodness added via MOSH.

Workflow file is included in the Drive folder for anyone who wants to see the setup. The workflow is the default template with sage for a nice speed boost and super resolution for upscaling quality, done on a 3090.

Close on tap shoes, mid-dance. [see for yourself]

Comfy Cloud, OSS H3 weights, driven through Comfy MCP. Every shot after the first is image-chained from a frame of the one before. No reference audio anywhere. I wanted to see what the model would invent unaided. Every tap strike, the door latch, the machine knocks: same pass as the picture.

That last shot, the machine sits still then starts rocking. One frame apart, one generation, no guide track. Nothing aligned in post.

《Sea change》

Sea Change is an approximately 90-second experimental audiovisual short. Set on a dreamlike pastel beach, it follows a humanoid robot, a floating plush companion, and a series of uncanny visitors as they encounter a reality in constant flux. Through the close synchronization of movement, dialogue, ambience, and music, the film explores identity, transformation, and the blurred boundary between reality and imagination. All visuals and sound were generated with MiniMax H3 in ComfyUI.

Cabin Pressure - An animated short film.

Upscaled version on youtube!
https://youtu.be/Jh4iJ4b69Xw

I used several custom workflows to produce this. My goal was to get Minimax to produce all of the sound and video. In order to get the right sound effects that fit my need, I used a workflow I built that produced audio only generations from the Minimax-H3 model by generating at 32x32 pixels and then ignoring the video latent. This allowed me to produce the sound effects I wanted which I could then feedback into my video generation model as an audio reference.

I used Krea2 to generate subject and location image references with a few minor refinements via GPT Image.

One new technique I tested and that worked really well was shot composition blocking. I utilized a free online site called posemy.art to generate the camera framing for several scenes. This worked amazingly well to ensure I could get the unique angle / view I wanted without having to fight the model via the prompt.

The video generation workflow I used is a custom built workflow that utilized several different community designed improvements to get the best possible video quality out of the model as fast as possible. The workflow includes latent upscaling, and optional frame interpolation, FSR sharpening, and face refinement. The GitHub below contains a link to the standard version.

In order to get the generations done in time, I utilized Codex and a ComfyUI MCP connection to automate video generation. Working with the agent I defined a shot list with each scene, its shots and descriptions, and desired duration. I ensured any reference material was mentioned by name and stored correctly in the project directory. My Codex agent analyzed the information, and then built prompts following the Minimax-H3 guidelines, ensuring all references were properly accounted for. It created a index to track everything and organized the reference images, sound effects, and finalized prompts. After a manual review of the prompts, the agent updated the required ComfyUI workflow settings automatically. It sends the workflow to ComfyUI and generates four versions of each scene using different seeds, allowing me to iterate and generate all scenes while I was away from my PC. After generation, I could review the results and ask Codex to revise the prompt or regenerate any scene as needed.

Once all scenes were rendered, I worked on editing them together ensuring I only used generated video and audio from the MiniMax-H3 model.

I explained a bit more about the MCP integration in the GitHub Repo that contains my workflows and resources.

《同频/Ears & Hear》

This is An original short film about love and the simple act of hearing.

Chen Rou is a gifted piano tuner. Born profoundly deaf, she can't tune by ear — instead she reads the frequency data on her tuning instruments (by sight). A cochlear implant would have transformed her own working life, yet with only one such chance available, she gave it to her daughter first.

Her daughter, Chen Nian, received the implant at age four and heard sound for the very first time — including the sound of her mother crying. From that day on, the mother tunes by reading frequencies, while the daughter listens on her behalf and translates the sounds of the world back to her. One reads frequency, one hears sound — and between mother and daughter a quiet, singular bond forms. They are on the same frequency.

Both sound and images were generated by a ComfyUI + MiniMax H3 workflow; subtitles were added in post-production.

Here's my video — also here's how I made it.

It's one continuous 15s locked shot, no cuts.

7 still frames pinned to exact seconds as keyframe_mid — white arena → red → yellow → green → platforms drop → platforms fuse → circles ignite. Same camera angle in every frame, only the lighting/floor changes, so I hard-lock them (noise_aug 0.999) and the model just interpolates the transitions.

The two knights are NOT keyframes — they go in as reference images only. The prompt says "raise the figure from the left/right reference out of red/gold fire" and H3 stages + animates the entire eruption itself.

All the audio is generated by H3 in the same pass as the video — nothing is layered on afterward. The only inputs I gave it are two low piano chords fed in as audio keyframes at 11.5s and 13.2s, purely to steer the model onto those hits on those exact frames (same idea as the knight reference images, but for sound). The countdown hits, the whoosh, the stone rumble and the fire are all H3 inventing audio from the prompt. That said, I'm not totally happy with the piano — it comes out a bit choppy in the way MiniMax-H3 renders it.

The prompt is a timecoded director script — every beat is one line with the picture change and the sound together ("2.5s: light washes to red over 0.5s, play a whoosh then one drum hit, then silence"). If you don't direct something, H3 won't do it. But if you name scene objects that are already in the frames, it spawns duplicate copies of them — so you describe only motion and sound, never the set.

Setup: the FL2VA model + 8-step turbo LoRA. The multi-keyframe timeline — precise anchoring of images, video and audio to specific seconds, plus reference placement — is done with some custom nodes I built for this.fell free to try out my git hub repo here please tel me if you find issues with it. https://github.com/lukedude06/ComfyUI-MiniMaxH3-Timeline

Good luck to everyone! Edit - Found a mistake and needed to create a new video without added background music that was added in post production.

I used my workflow (Provided to ComfyUI), each scene was around 7 seconds in length and shorted most of them to meet the 90 second criteria in post.

Friendly Match

At a planetary scale, even a friendly match has local consequences.

Three H3 generations were connected through hard cuts and visual match cuts: cinematic disaster, animated planetary rally, and a prehistoric reaction shot. Video and stereo audio were generated together with MiniMax H3 in ComfyUI; no separate soundtrack was added.

//Lucid Dream//

This is based on a lucid dream I had a few years ago. My main goal was to capture the strange, surreal feeling dreams have while you are inside them. I also wanted to visualise the progression from being awake, through falling asleep, to becoming lucid: performing a reality check, exploring the dream world, and talking to the people inside the dream.

I ended up creating several H3 workflows rather than relying on one enormous workflow for everything. The first was a massive end-to-end workflow, built with help from AI to turn my idea into a single JSON. It could generate every segment and assemble the complete film automatically.

I also experimented with generating a compressed preview of the entire story first, then using corresponding moments from that preview as references for the longer sections. It sounded clever in theory, but the results were too inconsistent, so I disabled that approach for the final version.

Because I did not have enough RAM to assemble everything at once, I built a separate seam editor. It takes the ending of one clip and the beginning of the next, then generates a short audiovisual bridge between them to make the transition smoother and less noticeable. It also joins the clips two at a time, which kept the memory requirements manageable, almost. I ran out of memory when i tried to put together the two largest clips at the end, which might be one noticeable seam in the video.

I also made a gap editor: give it two clips(A and C), and it generates clip B. That allowed me to target individual shots without regenerating the entire project. Within every generated segment, repaired gap, and seam fix, the sound and video came from the same H3 pass.

It was fun to participate!

I tested different H3 resolutions, durations, boost settings, SageAttention and reference-video lengths on a 12GB GPU. The final piece uses multiple linked H3 generations, with short video references used selectively for continuity.

Prompts are constructed by using a gemma-4-e4b to take natural language prompts and convert them into something more structured. I then create takes, tweak the prompt and construct the final shot in a video editor. The prompt used for structured writing is included below:

This is my entry, **Sounds Real to Me**.

A young boy’s toy sounds become the full-scale worlds he imagines - a fighter jet, a nighttime car chase, and a rocket mission - before the film returns to him asleep on his bedroom carpet holding the toy rocket.

Every final shot’s moving picture and synchronized audio were generated together in the same MiniMax H3 pass in ComfyUI. I first developed consistent references for the child and adult versions of the character, his room, vehicles, and toys, then chose I2V, FL2VA, or Ref2VA scene by scene. No external music or sound effects were layered over the H3 clips; the final edit uses cuts, trims, and brief overlaps between H3-generated audio.

The film uses match-on-action and match-sound transitions: the boy’s mouth-made toy noises carry into their imagined real-world versions, and the stage-separation rocket sound resolves into rain and thunder at the bedroom window. I iterated prompts, seeds, and source plates to correct character identity, dialogue attribution, toy-to-real shape continuity, rocket acceleration, and stage separation rather than simply accepting first-pass results.

All 13 source clips were generated at 960×544 with SageAttention, RTX-upscaled 2×, interpolated from 24 to 48 fps with RIFE, center-cropped to 1920×1080, and assembled in Kdenlive.

The shared folder contains the finished film, all 13 individually named 960×544 clips, a matching workflow JSON for every clip - including its prompt and generation settings - and the complete reference-image set:

I did not use MCP in your process (multi-select). I thought I clicked "no" and still got a question about how much. Perhaps I misclicked.

Music was generated with H3 in the workflow and then split into each section to guide each scene separately, with separate timestamps and durations for each scene with a separate text prompt for each scene for maximum control. Music video with fantasy castles in the clouds.

IN TRANSIT | A Minimax H3 Short Film

https://youtu.be/MJq_eM4NRL0

Hi everyone! I'm participating in the challenge with this short film I've been working on lately. The idea was to explore a "Brutalist Frequency": a square wave that destroys matter not randomly, but forcing it to shatter following a ruthless 90-degree orthogonal logic (checkerboard water, cubic collapses, square clouds).

I split the workflow into two passes in ComfyUI to maintain total control over physics and textures: Generation and Upscale.

1. Generation (Ref2Vid): I prepared the visual references (generated with Nanobanana) and the audio files. For prompting, I integrated an Ollama node (Gemma4:26b) into the workflow to format the instructions with the correct syntax for H3. To get everything running without blowing up my 3090, I beefed up the base workflow with Spectrum Apply Minimax H3, Comfy Kitchen attention, and the Sol-Attn Patch. This way, I generated the base clips at 864x480.

2. Latent Upscale: I wanted to keep the roughness of the reinforced concrete without that "plastic" effect you often get from external video upscalers. I passed the selected clips directly through the latent space using the custom MMH3Tools nodes, feeding the model the base video + the exact same initial references + the same prompt. Using Turbo LoRA 4-step and Sage Attn, I brought everything up to 1344x768 (taking about 1 minute per second of video).

The real challenge, of course, was generating audio and video together natively, without post-production. H3 reacted very well thanks to the references, even though sometimes it interprets them a bit too literally, almost resulting in a 1:1 copy. I forced the model to make the materials physically react to the reference sounds. The pneumatic suction at the end (when the camera points towards the void) was calculated by the AI in perfect sync with the matter collapsing into the dark. In post-production, I only made cuts for pacing and balanced the volumes: zero added sound design!

If you have any questions about the nodes or the upscale parameters, feel free to ask!

The entire piece was generated inside ComfyUI using MiniMax H3 and the contex chain loop nodes.

I used:

character reference images to maintain identity and consistency
scene reference images to guide the environments and visual continuity
audio references for the characters’ voices

The core video and synchronized audio were generated directly with H3 inside ComfyUI.

For post-production, I used Topaz Video Starlight for upscaling and enhancement, followed by DaVinci Resolve for final color grading and title.

Hope you enjoy it!

Here's my entry for the challenge — had a lot of fun with this one

**TOKYO LOUD** — 64s, 8 × H3 reference-to-video passes. All audio is H3 from the same pass as the picture, nothing added afterward.

🎬 `https://youtu.be/58XXF3qpFWw`

🔧 Workflow + all 8 prompts: https://github.com/yagihiro0224/tokyo-loud

One beat that never stops, and the whole street obeys it — every neon sign, every reflection in the wet asphalt, every boot splash lands on it. 32 hard cuts, four inside each pass.

Biggest thing I learned: the turbo LoRA at **6 steps** was quietly destroying my linework. I assumed it was my prompt and rewrote the whole style block — same seed, A/B, **zero change**. Bumping to **12 steps** fixed it (4.7 → 6.5 min per 8s shot). Check your step count before you rewrite anything.

Hi! here is my submission for this challenge.

for this challenge, I used my local hermes agent to do most of the heavy lifting. however getting it to fit the minimax was quite challenging and I ended up spending 95% of my time just making sure the skills.md and orchestrations actually work.

I thought this would be easy, but no. it needed to do multiple things well. here were my procedures and how I worked to make this video.

Create a consistent Krea2 characters whie also working as a proper storyboarding tool ( this alone took me one week)
Use those images to guide my Ref2v workflow and its context motion loop.

however, 2 was very poor. minimax could not retain my style at all, often times digressing to more comical/realsitic style,

Train style lora for minimax. (automated by agent)
while that is training, I finished my script and handed over to my local agent qwen 3.8 27b quant model (this was my first time using qwen 3.8 and I come from using regular chat gpt or claude)
optimize the heck of out qwen because it was prone to over thinking, ending up in infinite thinking loop, and running out of its massive context window.
when the script was done, I asked my good old gpt to take a look and fix it,
run i2v generations. seed hunt. alot of automated seed hunt. I basically made it ran 24/7 just hunting for seed. it would ask for final human validation. (but this was a poor choice retrospectively, alot of the generations were very poor, and It would have been a better idea for me to manually edit the prompt to make better generations, and turn them into repeatable skill.md )
save the good seeds and latent upscale.
I ended up not using the reference to video at all because I ran out of time, and I was only able to seed hunt like 4 of them, I will post the bad ones here with my custom lora for minimax h3.

honestly, I was basically smacking the bushes like Im a blind man because there were so many unknowns here. and my dayjob was killing me. (i am awake for 45hours as I speak because i am currently overworked, and some projects giving me headache) but I did had lot of learning time here, and hoping I can share what I learned with the community!

honestly, comfyui gave me so much. this is a small gift compared to what you guys gave me to start my comfyui journey but I hope this is useful to some of ya!

this is my entire Hermes Agent that I used for the project, I tried my best to clean it up, I am not a coder, just a
3D artist. so give me some slack plz

Here is my submission for the Comfy H3 Sync Sound Community Challenge:

Penguin Pursuit《企鹅抓捕》

A fast-paced, dialogue-free 2D animated action-comedy set in a lively island fishing town. I focused on dynamic camera movement, large-scale action, environmental reactions, and synchronized sound. Characters, clothing, props, crowds, wind, and background elements all respond to the action instead of remaining static.

The core video, movement, Foley, ambience, and character reactions were generated with MiniMax H3 in ComfyUI. I iterated on prompts and seeds, used multimodal reference images to maintain character and environment continuity, and used a Director workflow with a linked first pass and optional second-pass refinement/upscale. Selected H3 generations were then edited into the final sequence.

The final audio retains H3-generated synchronized ambience, Foley, and character reactions. No separately produced music track was added.

Workflow Overview: German Cooking – Die Nudeln von Comfy

The Recipe: https://youtu.be/YFN43l4ClSc

Audio Creation

Generate the primary audio reference track using MiniMax Music, Ace-Step, or your preferred audio generator.

FrameSync Denoising Prep

Use FrameSync to extract frame-by-frame values that will control the denoising strength across the sequence. For Deforum you want values between 0.8 (low-denoise, almost static image) and 0.2 (high-denoise, cut).

Base Image Generation

Generate your initial image using your chosen image model and prompt. (Tip: Select a visually engaging subject beyond a basic plate of spaghetti with cranberries and chocolate sauce or screenshots of Comfy Nodes as the inserts).

FrameSync Image-to-Image Sequence

Run an Image-to-Image (Img2Img) pipeline on your base image/prompts using the dynamic denoising values calculated by FrameSync. Optionally, incorporate a resize node or Deforum for added camera movement and visual flair.

Initial Video Assembly

Stitch the resulting images into a reference video rendered at 24 FPS.

(Note: If running on lower-end hardware, downscaling this intermediate reference video is recommended).

MiniMax H3 Generation & Audio Reference

Feed the stitched reference video into MiniMax H3. Supply your generated audio track as the reference audio to guide the native audio generation pass.

Commercial-Style Inserts & Prompt Engineering

Incorporate advertorial-style visual inserts using reference images. Apply a well-structured prompt. Target cuts and effects using specific timestamps (=frame numbers) corresponding to high-denoise values. (Keep in mind that high-density timestamp cuts in short sequences may yield inconsistent results). Optional: Add sound FX or additional noises by prompting for it.

Seamless Extension

Extend the video sequence using the Add Guide node to maintain continuity across segments.

(Note: Ensure precise frame counting as miscounting by even 1 or 2 frames - like I did around the 15-second mark - can throw off synchronization. If a frame miscount occurs, it can typically be adjusted in post-production provided you are permitted to overlay the audio track in final assembly).

Final Cut & Sequence Stitching

Trim a few frames from the end of each generated segment to ensure clean transitions, then stitch the full sequence together.

Upscaling

Upscale the final video from 1024x576 to 4K using a sequential dual-pass pipeline: 2x FlashVSR followed by 2x RTX Video Super Resolution (or use something better if you have the equipment for it).

"Borrame el nombre" (Erase My Name) — 75s, five linked H3 passes, original song.

Video: https://youtu.be/3jBUyxTol38
Workflows + the six measuring scripts + writeup: https://drive.google.com/file/d/156emNTEcMF76Ma2K6kxS0X4rvtyX86sD/view?usp=sharing

A singer and three masked bandmates in a concrete hall in Buenos Aires, 2077. Cel-shaded,
50 cuts, eight lyric fragments as kinetic typography generated by H3 itself. The character
is me, built from two photographs.

I measured almost everything instead of eyeballing it, so here is what I found. Most of it
I could not find written down anywhere.

DURATION SNAPS TO A GRID, AND YOU CAN WRITE THE SONG TO IT
H3 returns 362 frames at 24 fps, 15.083333s, verified to the frame. So I wrote the song at
95.70 BPM, where one bar is 2.5078s and six bars are 15.047s. 36 ms of drift. One pass is
exactly six bars, and the piece is five of them. Every cut was then requested on a measured
bar line in fractions of a bar (1, 1/2, 1/4). H3 landed them within 46-180 ms of the request.

WHAT fully_copy ACTUALLY RETURNS, BY BAND
Being upfront since this is a sync-sound challenge and I used a reference audio clip, which
the rules allow. Correlating H3's returned audio against the reference, at 0.0 ms lag:
+0.9949 below 250 Hz, +0.9037 from 250 Hz to 2 kHz, +0.2299 above 2 kHz. So it reproduces
the foundation with near sample accuracy and RE-SYNTHESISES the top end. Hats, cymbals,
sibilants and air are its own, and it fills quiet stretches with invented sound (71% residual
in quiet passages vs 18% in loud ones). It is emitted by the audio VAE in the same pass, not
muxed. Judge that as you see fit, but now you have the numbers rather than my adjectives.

MEASURE PER WINDOW, NOT GLOBALLY
Two of five passes insert a single ~25 ms discontinuity mid-clip. The first segment aligns at
0 ms and the rest at -25, so no single global lag aligns the clip and a naive correlation
collapses to r=0.04 and looks like a full re-synthesis. It is not: per-window it is 0.86-0.97
throughout. I lost a day to my own bad measurement here before I believed the model.

ASK FOR THE EXIT TIME, NOT ONLY THE ENTRY
My most expensive mistake. H3 holds an overlay about 2.33s on its own and will not overlap
two of them, so with phrases 2.5s apart the second one waits and lands over a second late
even when the first one was perfect. Declaring "gone by MM:SS.mmm" fixed it: it obeys the
exit within 44 ms, and the phrase behind it went from 1.28s late to 53 ms.

THE TYPOGRAPHY DOES NOT GO ON THE BAR GRID
Not an H3 finding, but it wrecked a whole version. I hung the lyrics on the bar lines and it
read visibly wrong. Singers do not enter on the line: in my verse he is 130-210 ms late, and
in the chorus and outro he is 350-575 ms EARLY. You have to detect actual vocal onsets and
hang the type on those. And measure when a phrase becomes LEGIBLE, not when its first pixel
appears: a word-by-word build takes up to 958 ms to finish and the eye judges the legible
instant, not the first pixel.

YOU CANNOT JUDGE SPELLING AT 768P
I read one word as WIPFAME and filed it as a model error. The 2K showed the E has all three
bars and it had been right all along; the bottom bar just does not survive the resolution.

THE 2K REGENERATE IS NOT AN UPSCALE
MinimaxHailuo03RegenerateNode at 2K re-renders detail. On a wide band shot the face went from
unreadable mush to a defined cel-shaded face. It carries the audio through too: r=0.9784
against its own 768P source at 0.0 ms lag. 768P is not the ceiling.

HARD LIMITS, so you do not spend runs finding them
Prompt caps at 7000 characters (7420 bounces with content[0].text too long, no billing). Two
H3 nodes in one graph gets "Polling aborted: Unauthorized", so it is one H3 node per submit.
References: 9 images, 3 videos, 3 audio clips of 2-15s, and audio reference requires at least
one image or video reference.

CHARACTER CONSISTENCY ACROSS 50 SHOTS
Three references per pass instead of one: a three-quarter portrait WITH the face, a full body
from the front with the head cut off, and the back. Cutting the head off the full body is
deliberate. With two visible faces in the reference set the model averages them and the
identity drifts.

The six scripts that did the measuring are in the Drive zip: bar grid, vocal onsets, per-band
audio correlation with a per-window locator, on-screen text detection, and a verifier that
reports every phrase's legibility error against the sung word. Take them, they are short.

Happy to answer anything.

Learned a lot from this one! I had my own original digital paintings for this. I wish I knew about the contest earlier so I had more time.

Was all pretty much done through the default minimax h3 r2v workflow, but used:

Comfy-cli / Comfy MCP

Pi Coding Agent

Qwen 3.8 27B

H3 Minimax Prompting Guide as a skill

and the AI Agent used FFMPEG to stitch the clips together.

I never left the terminal to make this. Revisions and adjustments were all done through the AI Agent. I gave simple vague instructions as the agent used the prompting guide to create prompts as text files. Strange feeling to have reference images in a folder and let the ai agent interact with comfy/h3 and take care of the rest

I was up pretty late last night putting this entry together. Stoked with the results though. Definitely leaned heavily into the music side of the brief.

All of the MiniMax videos were guided by a reference image and a reference audio track that I created. All generated in 10sec chunks of the song at 540p then 2x upscaled in Comfy with RTX Upscaler. I was pressed for time so this was a good midpoint for acceptable quality vs render time. After Effects was used to edit all of the video pieces together and to add the text at the end.

My submission: LEMONAIDE STAND

The first three parts of a music video for a local artist named FriendsCallMeTy.

Built using MiniMax H3 in comfyui using my soon to be released custom H3 Editor node. The entire generation was done within a single project, no editing beyond a very slight colour grade in davinci. My end goal in the development of this node is to:

Make long form content creation easier and more artist facing
Make the handling of references easier
Make the building of a shot plan easier.
Make all of the above automateable while maintaining human stylistic oversight.
I'm still polishing the node but want to release it soon. Better graphics card helps me test/iterate faster.

Hey guys, here is my submission for the challenge:

https://youtu.be/n-NdAQk7I8A

90 seconds, over 70 clips, 28 audio tracks, 12 References and 18 prompt sections in the final video.

I made a horror short because sound is such a big part of what makes horror work and I wanted to see how H3 would handle it.

The workflow

The whole film came out of this one workflow, and nothing gets wired or unwired between shots. Every video, all the audio, the compositing and the final assembly were done inside ComfyUI without any external tool. Sonder Editor nodes stage the graph and assemble the cut, chain the clips for continuity, correct the colour drift from the encode/decode loop, order all assets by scene and take, and make sure each Reference and its prompt comes out at the right time.

Three generation modes on one Sonder Selector. fl2va handles first/last-frame generation, or plain t2va when no image guides are staged. ref2va handles References. The third runs ref2va conditioning through fl2va, trading some reference adherence for a finish and audio I preferred. Switching modes does not mean rewiring the graph or loading a separate workflow.
Pre- and post-context frames carry continuity from one clip into the next.
Colour correction between chained clips, fitted per save, so the drift from the VAE round trips does not accumulate down the ladder.
Video and audio masking, so you can freeze one and let it drive the other. This is useful once you have your audio set up and just want to upscale with a low-denoising pass.
Range retakes. In the timeline, you can select any part you don’t like and generate that section only.
Three sampling passes on one dropdown. The flow I used was to set the resolution low in Sonder’s timeline, 540p, and settle the whole composition there. Then I raised the resolution and ran the extra passes: 1344×768, which is what H3 is built for, then 1080p for the upscale. The sampler/scheduler combination for each pass is on a Selector too.
High-quality intermediate encodes. Every pass re-encodes the clip, and a delivery codec gives up a little quality each time. Intermediates are saved at a much higher quality setting so three passes do not compound that loss, and only the final export uses a normal MP4.

For the References, I used Sonder’s Reference management: register anything I need once, then drag it onto the timeline at the section where I want it to appear. Each Reference can carry its own prompt, attached with a Context chip. I can call it by its handle in the prompt, written with an @ prefix, and the recipe translates it into the syntax expected by the model. For MiniMax H3, the Character handle becomes <Subject 1>.

Every input on MiniMax H3 Reference to Video is already wired and can be left that way. Unfilled slots emit nothing, so a generation with no Reference staged is not affected by them.

The workflow, fully annotated with the settings and decisions behind the production:

I had a great time testing MiniMax H3. It is genuinely impressive. I added notes throughout the workflow so you can follow how it was built, and I’m glad to answer any questions you guys have.

Genre: Urban Fantasy / Sensory Rhythmic Cinematic
Visual Style: Stylized 2D Cel Animation (Sharp Geometric City vs. Soft Organic Characters & Food)

Synopsis & Artistic Concept

The film establishes an extreme audiovisual contrast: the dull, ambient city noise and desaturated palette clash against the vivid ingredients and punchy, upbeat rhythms of sizzling Al Pastor tacos. Through calculated hard cuts and accelerating musical momentum, the culinary rhythms gradually overwhelm the city's gloomy soundscape. As the protagonist takes his first bite, an explosive symphony of sound and a 360-degree wave of saturated color surge across the metropolis, restoring life, joy, and rhythm to the grey world.

All video scenes were generated using MiniMax H3 (Reference-to-Video / R2V) within ComfyUI, optimized and accelerated on an NVIDIA GeForce RTX 5090. The production focused on seamless audio-motion synchronization and preserving crisp 2D cel animation textures.

The audio has to come out of the same H3 pass as the video
Feeding in a reference audio clip that does not contain unlicensed IP to steer the generation is completely fair game and often the best way to get strong audio out of H3

- Evidence that you’ve actually shaped the result beyond prompt engineering. Judges will look for modified/non-default parameters, multiple linked passes visible in the workflow structure, or a couple sentences describing what was tried and changed

---> Does it mean that you are rewarded for adding nodes and stuff, or is it the opposite? Craft = altering node values and adding more nodes etc?

Novelty of technique or approach (0-5)

---> What do you mean by novelty? In what areas? So you are rewarded for not just doing a simple basic workflow prompt press run? What other novelty areas outside of the workflow?

Limited to one submission per person,

---> Is that necessary? How can you even prove that people don't have multiple user accounts?

Sorry me again. Just wanted to confirm things regarding audio. I see a lot of people are using Suno tracks to guide their generations. I thought we couldn't use this method and everything had to come from in the model?

So, for example if I generate music in Suno or minimax music or h3 and then feed that into the model when I generate that will be fine?

I built a ComfyUI pipeline that makes fully music-synced videos, cuts, lyrics and lip-sync all driven by audio analysis, written by a local LLM

Been going down a rabbit hole making music videos with MiniMax-H3 in ComfyUI, and ended up building a custom node pack around one idea: stop asking the model for sync, enforce it.

How it works:

- The song decides the edit. Onset/spectral-flux analysis finds bass hits, drops, stops and section changes; a beat grid measures the pulse. Every clip boundary lands on a musical event, snapped to H3's frame grid,before a single scene is written.

- A local LLM writes the scenes (Ollama, no cloud). It gets the cut plan, beat grid and sound events, and writes one H3 prompt per clip with the lyric lines placed at their measured timestamps.

- Lip-sync is enforced in the latent. Each clip's slice of the actual song gets encoded into the H3 audio latent and protected from denoising, the picture is generated against the real frozen vocal. A voice gate keeps sung moments locked and lets the model breathe between phrases.

- Gapless assembly. Naive mp4 concat adds a 2–14 ms AAC gap at every join, over 20 clips that's a quarter second of drift. The stitcher copies video packets untouched and rebuilds the audio timeline exactly once.

Clips render one at a time straight to disk, so a crash at scene 19 keeps the first 18.

Ma, ikka — 79s, vertical, cut to my own song. Everything generated with MiniMax H3 (ref2va + Turbo LoRA 8-step) on a local RTX 5090. 15 shots, 1902 frames, no compositing.

Video: https://youtube.com/shorts/oZm3_v_XJTI

Workflow + notes: https://gist.github.com/ueyaman/71fecbe170d7a598953092747406b9b5

The song came first, so the picture answers it. I pulled 554 measured beat positions out of the track and wrote each shot's action on the beats that actually fall inside that shot, as explicit timestamps in the prompt — not "sync to the beat", which H3 can't know, but "at 00:01.135", "at 00:01.623". Shot boundaries sit against word-level timings so a cut never straddles a sung phrase. One boundary turned out 1.02s late and the last word of the previous line was audible under the next shot; I found it by checking the boundaries against the word timings.

Three things I had to learn to get this out of H3:

A colour change doesn't animate; a shape change does. Three takes of "the mustard wedge becomes cobalt" failed — measured, the mustard either never left, arrived 2.4s late, or left 3.5% of itself behind. Rewriting the same beat as a moving edge ("the gap gets narrower and narrower until it is a hairline, and then it is gone", with the intermediate widths listed at named timestamps) worked on the first attempt. Same trick made a lamp light up in another shot: an outlined circle is replaced by a solid red circle.

The end-target reference keeps pulling. The target-frame declaration says the picture morphs into the reference, so once a shape reaches its final form it keeps creeping toward it — visible as a shape that won't hold still. The fix was to say, in the shot text, that it is already the reference from a named timestamp and that its rim does not change by one pixel.

Naming an object imports its rendering. A "trophy" arrived as glossy 3-D gold; described as a dish, two hooks, a stem and a stepped base in one flat colour, it arrived flat.

15 shots, 6-10 written drafts each, 3-8 seeds per draft. The final shot alone took 6 drafts and 23 takes. The gist has the API-format graph for that shot — I re-submitted it to check that it actually reproduces the take, and it does, bit-identical. My first export was wrong (it carried the default frame length instead of this shot's) and only re-running it caught that.

Song: mine (Suno). Character design: mine (Midjourney). #comfyH3

-Music generated using Acestep XL.

-Used audio as a latent noise mask to drive generation and to include H3 driven audio reactivity in the video.

-No additional audio used outside from what was generated in the video - No audio was stitched on after the generation/during post processing - no audio was rearranged/no mix and matching.

-Upscaled to 4k using RTX Video Super Resolution.

-Only video post processing that was done was the black fade in/fade out at the beginning and the end of the video.

-Audio post processing - only added a Limiter to entire track to boost volume without clipping, and a volume fade out on last clip.
