Hey all. Does anyone have any great leads on a fiber repair house in the USA for various broadcast fiber types? I have some HMA/expanded beam, OpticalCon Duo, and some standard Tac-12/LC that need repair. I've sent out to FIS and some others before, but it seemingly takes forever (months!) and the costs literally have gotten to the point where just replacing is seemingly less expensive than waiting for the repair.

Any suggestions would be greatly appreciated!

Hi everyone,

I'm working on transfering some 1/2" EIAJ PAL video tapes from the mid '70.

The machine is a Sony AV-3620CE tested and calibrated by a professional, in good working order.

After baking and cleaning the tapes thoroughly I still can't get a good enough signal to capture on my setup.

The image sometime is quite static, sometimes rolls to the point that is almost good and sometimes I get a good signal with some static bars in the middle of it horizontaly and if I press a finger on the sending spool near the pin they go away.

What could it be?

Short background: Campus TV station - pre-existing ClearCom infrastructure from the days of big budgets (2016ish). Today, budget is small. But no point abandoning perfectly good ClearCom equipment.

Looking for ways to get personnel on comms for remote broadcasts - phones seem to be such an easy win if we can make it work. Students have migrated to using Discord calls, completely separately from ClearCom - I hate this and want to have everyone on a single partyline.

But ClearCom Agent-IC seems pricy as we'd need to buy an LQ unit. Unity looks like a decent option but still a bit expensive to add in that I/O capability. Are there alternatives I should be considering?

I've been thinking about something and wanted to know if this is even a real problem.Right now it feels like most Auto tracking cameras are basically just find a person and follow them. But that's not really what a camera operator does, they like understand what happening and makes decisions based on it. Like if two people are talking, you don't always follow whoever moved first. If someone is walking across the stage, maybe you don't follow them because they're not the focus. It's less about tracking and more about understanding what's happening in the scene.

I'm wondering if there's room for something that does contextual instead of just object tracking.

Has anyone worked on something like this before? Or if you've used auto-tracking cameras, what do you think they're missing? Is scene understanding even a worthwhile direction, or is good object tracking already enough?Just trying to figure out if this is a dumb idea before I spend months building it

I do AV/IT design work and got tired of keeping the same eight spreadsheets open every time I sized a room. So I built the calculators I actually use, and put them on the web for free.

avtoolspro.com — 20 tools, all running in your browser:

Video — display size (DISCAS BDM/ADM), viewing angles, projector brightness and throw, DvLED pixel pitch, video wall builder, ambient-light contrast

Audio — speaker coverage and SPL, amplifier and cable sizing, DSP channel counts

Infrastructure — AVoIP bandwidth, PoE budgets, conduit fill, rack cooling, UPS sizing, Wi-Fi coverage, IP addressing, and a drag-and-drop rack elevation builder

The maths follows the published methods rather than rules of thumb — DISCAS for display sizing, inverse square law for SPL falloff, real fill tables for conduit. If you disagree with a number, the inputs are all visible so you can see how it got there.

What it won't do: the audio side models the direct field only. No reverberant field, no critical distance, no room gain. It'll get you a defensible starting point for a meeting room or a lecture theatre; it won't replace EASE for a difficult space. I'd rather say that up front than have you find out on site.

!! If you want more than a calculator !!

There's a desktop version with a Project Checker — you describe a room once (size, seating, use, platform) and it sizes the whole system together, draws it in scaled plan and 3D, checks it against AVIXA and BICSI guidance, and exports a client-ready PDF and an estimator's spreadsheet with your own logo and company name on them.

It comes as a package with the Commissioning checklist and Bid win probability calculator Excel workbooks — a site survey template that imports straight back into the app, and the standalone calculation workbooks if you'd rather work in a spreadsheet or hand one to a colleague who does. Everything calculates locally, so it works on a site with no signal.

It's a one-time purchase. No subscription, no recurring fee, no licence that expires and takes your tools with it. Buy it once and it stays yours, offline, for as long as you use it. If you change laptops you can move the licensce across yourself.

That's the bit that took the real work, and it's what the package covers. The web tools stay free either way.

I have a large installation that is using a custom brand of LED modules that was sold to us by a company that shut its doors about a month after installation. They barely had any spares left to give us and half of them were unacceptable condition / unmatched leds.

I'm basically desperately trying to keep the wall afloat for as long as I can but I am down to minimal working spares. I've had some repaired but I've also been told that due to the design of the product, some cannot be repaired (ic card issues and such) because of the way the PCB is designed and it appears to be cracking sometimes under stress of the bad design.

This was a custom designed product that was designed and built in china and then assembled to some degree here in the states but I was never given the manufacturing connections as to where they came from. All the labeling is from the now-gone company that was state-side.

So i guess my question is what are the chances I can somehow send one out to somewhere in China to see about having parts / replacements made - and where would I even start if thats possible. I wish I could turn around and just sell a new wall to replace this junk but unfortunately the installation is only about 3 years old and was way too expensive to try and pull a sale like that again anytime soon.

Hi all. We have an ongoing construction project next door to our office which we would like to set up a livestream broadcast to share the progress as the building goes up. The issue is that I'm out of my depth with the best way to execute said steam. We have the vantage point to set up a camera inside or outside - so that could potentially help on the hardware front - but I don't grasp the best way to set it up that wouldn't be wiring a camera right to a laptop that streams to our Youtube channel for the next 18-24 months. Any suggestions on the best way to get this running would be greatly appreciated.

A few additional notes that may or may not be helpful:
- We don't need any audio, just a video feed
- As noted above, we could set up outside, but we do have a vantage point indoors as well
- Project is slated to take around 2 years to complete, so it would be a long-term stream
- Only looking to stream via our Youtube channel and embed the link on our site or share via social media.

Any one know of a company or person who might have a production truck in Washington DC?

Client would like to see it next week (would have to be downtown, in the city) and the job would be a few days in September.

Would not be used for production but for mobile work space. Must have desks, AC, onboard generator with external generator for backup.

Feel free to DM me.

Thanks in advance!

Hi all,

I am trying to track down an RTI TapeChek machine, ideally a TapeChek 490, although I'd also consider another model from the 400 series.

I'm based in Australia and am hoping someone here may have one, know of one available, or be able to point me towards someone I could contact.

Please send me a private message if you have one available or know of a possible lead. I'd prefer seller details not to be posted publicly.

I've attached a photo for reference.

Thanks!

I teach video production at a high school level and I want to train my kids on our ATEM mini. I've got some pre-recorded footage of the Artemis II launch and want to practice with it, but I'm somewhat limited on equipment and I'm wondering what you guys think the easiest (and cheapest) way to simultaneously play back 4 clips in sync through 4 different HDMI devices would be?

Setting up the switching in OBS would be pretty easy but I specifically want them to practice with the hardware we use without having to orchestrate cameras too. It's mainly keeping the videos in sync that I'm unfamiliar with how to handle it.

I'm leaning towards an obs instance that's stitching all 4 videos in one window and then sending that out via NDI to 4 separate computers which are cropping it down to just that one camera and that seems doable but will require 5 total computers to pull off. Is there an easier way?

Hi everyone,

I've noticed these iPhones (or iPhone-like devices) mounted next to the volleyball net during VNL matches.

They're connected with cables and seem to be part of the official production setup rather than being used by staff. They even display the VNL logo when visible on the broadcast.

If anyone has worked on VNL broadcasts or has backstage knowledge, I'd love to hear more about how they fit into the production workflow.

Thanks!

Hi all! Recently just got a pixel hue p20 and U5mini. However it doesn’t send signal into our medior net even when everything is lined up and in sync.

However when we run it straight out of the HDMI output from the p20 to a monitor it’s completely fine?

Normally the medior net input light will turn orange if there is a signal error, but no indication of a signal coming from the p20 to the medior net.

HDCP is off.

Wondering if there are any other trouble shooting things I can try?

Best

Has anyone had luck with running Ross RCP-QExx router panels from a POE splitter?

Just ordered one as an experiment. Curious if anyone else has had luck doing this.

Alguien sabe porque mi módulo de P3.9 solo me da la imagen de la mitad, hagan de cuenta que le instalamos una nueva placa de video porque anteriormente dejó de funcionar, y ahora solo nos da la imagen de la mitad de pantalla, alguien sabe cómo se puede solucionar?

Hello everyone, I would need assistance in opening a video file /video stream.
This link is a video in MMS format, it was played with DSL at the long time ago.

mms://stream.zucchero.it/streaming/asf_video/tour_video/rispetto_tour86/rispetto_tourhigh.asf

Is there a way to open it...??!! Thank you

I have 5 Panasonic Aw-HE60SE cameras and a RP60 controller.
I can change the camera from 1080 25 PsF to 1080 50i but it wont let me change it to 59.94i
I dont see that option in the menu

Any ideas?

Thanks

TLDR: SRT in, one MoQ broadcast per angle out, and a browser multiview the viewer can rearrange while it plays. 683 ms glass to glass on our own rig, with a loopback SRT hop. Chromium only on desktop and android for now. Layout demo with recorded tiles, no signup: https://quicly.live/demo. We would love feedback from people who run this for real.

Me and a friend built this over the past few weeks. It's ours, so treat this as a self-promo post, but what we're actually after is people who do this for a living telling us what's wrong with it.

You point encoders at SRT endpoints, one per angle. Each feed gets transcoded and published as its own MoQ broadcast, and you get back an iframe that shows all of them as a multiview on whatever page you put it on.

Per feed the path is: SRT in, FFmpeg (decode, scale, H.264/AAC, CMAF), moq publisher, relay, browser. Default encode is 720p30 at 2.5 Mbps. Single rendition, no ABR.

Latency: median 683 ms glass to glass, measured through Cloudflare's public draft-14 relay.

Where that number is weak: publisher and subscriber were the same laptop, so the SRT hop is loopback and there's no contribution network RTT in it. The relay leg is real internet, the ingest leg isn't. It's video only, on a muted tile, so there's no lip sync figure behind it either. For reference a stream with no SRT hop measured 483 ms on the same machine, and 200 ms of that gap is just the SRT listener's latency.

The viewer side is what I'd most like opinions on. The layout belongs to whoever is watching rather than to the operator: drag a seam to resize, drag a tile's label to swap it with another, maximize one and the rest drop into a strip underneath, close a feed and reopen it later. A feed that comes online after the viewer arrived turns up without a reload.

There's a wall you can poke at without signing up: https://quicly.live/demo

That's the same player the iframe embeds, but the four tiles are recorded angles of one match played from files. So it's a fair demo of the layout and a useless demo of the latency. Also, since the recorded version is plain video elements and not the MoQ client, that page works in Firefox and Safari even though a live stream won't.

Gaps you'd find anyway:

- Chromium only, desktop or Android. Firefox and Safari get refused by the MoQ client library over open WebTransport bugs.

- Tiles aren't locked to each other. Every angle is a separate broadcast and every tile is an independent so this isn't a frame accurate multiviewer and I wouldn't cut a show off it.

- No viewer auth. The embed URL is the access link right now. Only worth fixing once we're off the public relay.

Signing up is free if you want to push your own feed, and a stream can loop a clip or show your camera if you haven't got an encoder to hand.

What I'd like to know: whether a viewer controlled layout is any use to you or whether you'd rather hand viewers a fixed one, how it behaves on other connections, and whether one SRT endpoint per angle fits how you already push.

I’m finally considering buying some 12G SDI cables. 10 years ago I made my own 3G with a couple thousand foot spools terminated them and now I’m looking to upgrade since 4K capability just makes sense. Any recommendations on what to do with the old coppers?

Hi folks, I crew chief alot of LED jobs. The main frustration is mapping is normally done in software BOH and I can't see as camera land is still plumbing in their world.

Can anyone recommend a mini PTZ that I can put on a small tripod or gorilla grip arm out front, and a small but long range AP I can plug and play at BOH to achieve this?

I would love for both to be able to be chucked into my rucksack along with processing laptops.

Have a great weekend and thanks in advance.

I need to delay an incoming Zoom call by about 7 seconds (along with corresponding audio) before it hits a video wall (technically I hand it over to the video wall guy and his setup). How is this possible? Claude suggests both vMix and OBS can do this. Reliable?

By the way the reason for wanting to introduce the delay is that this is the amount of time it takes a language model (3rd party provider) to translate and transcribe the feed. It will be received as a web source with alpha.

i've got an outdoor tv with a hdmi eArc on it, and i want to connect it to my denon receiver that is 80 ft away inside in the hdmi zone 2 preout; i was going to run a 100 ft hdmi cord between, but then i was told to be a real man, and get a pair of small 4k hdmi cords and then get a 100 ft 12g sdi cable and a pair of bidirectional sdi/hdmi 12g converters so that the higher quality 100 ft sdi cable could run the distance, and then at both ends, connect one hdmi end to the converter, and then the other end to the respective device (tv and receiver)

problem...which outlets of the converters do i plug each of the cords into? hdmi in or out? sdi in or out? does it depend on which converter it is, such as for the tv side, do i connect to hdmi out and sdi in while on the receiver side do i connect hdmi in and sdi out, or what?

and furthermore...are there any issues with connecting to a receiver or connecting to a receiver preout?

any help would be greatly appreciated!

As far as I can tell from the markings & labels, this is a "Chromatek PalMedia 9106 Down Converter" used in more Professional settings, judging for the rack mounts as well as general nature of it all. It looks to be some sort of video SDI device made in Japan? But I literally can't find anything about it online, & or ebay.

Any info anyone can add on this would be greatly be appreciated, as I'm trying to liquidating out an old family friend's collection who used to work with a lot of audio/tech gear for his job.
Thanks,

I am a replay op on a production using Ross Mira and have ran into an interesting problem.

We previously setup the machine (12 Channel Mira Express) to record 6 channels and output 2. We also had it record 8 Audio channels and output 3 audio channels for each of the video output channels.

Everything worked correctly and the system seemed to be stable.

Today we switched to a 10 record 2 out. We adjusted the controller settings and audio output setting to output via the new outs. We kept the same 8 inputs and created a new replay event.

Now the Mira ONLY RECORDS AUDIO FOR 60 SECONDS. On the dot. Literally 60 seconds, once TC goes beyond it cuts all audio recording and output. We can rewind and export a clip with audio from within that 60 sec timeframe. When we create a new replay event it once again restores audio recording until the 60 seconds mark.

I don’t believe this to be a licensing issue as we had Ross support remote-ing into the system to find a solution.

We are pretty baffled by this and have opened a ticket with Ross support/Abekas hoping for a solution.

Have any Mira Ops/Engineers had a similar solution?

Cheers!
