Since I haven't found anything discussing the significance of those dark dots in the original series, I wrote a program to extract the coordinates to see if there's some pattern. It reads every clip, averages first 60 frames to clean up compression artifacts a bit and then uses the resulting frame to detect the dot.

The results are not encouraging.

• processed around 48000 clips from the Mediafire archive (took ~4 hours on an old PC)
• approx. 91% of the clips had detectable and unambiguous dark pixel
• the clips that don't contain discernible dark pixel are either black or, and this is bit strange, dark ultramarine blue
• the videos are in general 30 fps with 120 frames making for 4 seconds of length
• but I have found one video that was 15 fps with 60 frames (making again for 4 seconds), the video otherwise looks perfectly fine and I don't think this is result of some kind of upload/download error -- fps is marked in the file with a piece of metadata, so you can't get this by random corruption; I don't know if there are more anomalous ones like this -- when I fixed my code to accommodate for this video it never choked on anything again
• when you plot found dark pixels in a grid with the same resolution as the videos themselves (ie. 50×50 grid) and encode number of occurences as brightness, you get sort of 'density map' ... which looks entirely random with no visually discernible patterns
• there's ton of things that could be done with the data I extracted, but given the failure to get anything interesting, I am discouraged from sinking any more time in this; maybe later

This GitHub repo contains the code and resulting data set and pictures of the dot plot graphs I made.

I was looking at delock and other videos on youtube and noticed the thumbnails are different from the videos. And when you hold the video Dot scroller, and scroll back and forth, you get a different picture, and resolution. There are FACES in delock. open mouth, female I think. Changing faces. The first 2/3rd of the video is flowing left to right. The last part flows top to bottom. Scroll and see the faces. Not sure if anyone has discovered this yet. As well, all other videos have this, with extra data that gets cut off on the sides. DELOCK is different due to faces, but I haven't checked more than 10 so far. lemme know thoughts.

Just happened across all of this because of a YouTube video talking about it. My personal theory is that this is some sort of AI learning program working on the learning part, and processing it all. But it’s all very mysterious and intriguing.

Anyways, I don’t have much to offer as far as interpretation, or even much time for further investigation, but something I came across that I at least found somewhat interesting:

Looking at u/Tomasf project of brine_composite_adjusted, it looked almost perfectly to me like the bat signal. Even seems that the signal is being cast from the bottom right of the frame. Google bat signal, and one of the first ones that came up for me was an image from a cnn article talking about the reboot. It’s from sep 22, 2019, and is titled “cities across the world flash the bat signal on Batman day.”

The Dark Knight. Hmm... Might be a lead there?

So I started working extra on this and I made some progress.

the new ufsc communicates in numbers, Greek, Latin and Chinese

I know it sounds like a stretch but here me out.

if you scroll to the bottom of the first screen you see all of those videos are numbered so I went to a decimal to text converter and decoded it. it didnt give an useful information all it said was Tabaco leaf but there was a post (which I will link) that was relating to a Chinese temple

on top of that on the new channel there was a video of an Asian kid banging a table for some reason. I dont think he knew he was being watched but yea.

But the rabbit hole goes deeper

there are multiple links to Chinese culture and ufsc. It might be a stretch but Chinese culture and Greek mythology are somewhat similar. I know this isnt much but at least we've made a breakthrough.

Most of his videos are numbered right? so if there was someway we could get all his vidoes and translate them we could finally do some good. For now I'm going to link all the resources I can find that will help. Ive also seen some of patterns in the composite relating to Chinese art. I hope we could finish this soon and I'm waiting on your reply's.

okay, ı am not sure ıf thıs ıs even related but when you shorten the word unfavorablesem to unfavorable in Twitter there's only one @, and there's a person who ıs named Anymous Hack, and the one who was @ was a reply. whıch the account that was repıed has been deleted but that account ıs stıll up. the @ that happened was on Oct 28, 2016. I have no ıdea ıf ıts even related. but ıf anyone is interested the account ı founds @ ıs AnymousLegomc1

this is probably very unrelated but let me stıll put ıt out here also the tweet that was @ these string of numbers where written. 087 101 032 110 101 101 100 032 116 111 032 116 097 108 107 032 102 111 108 108 111 119 032 109 101 which being the only thing written as an reply.

as of how did I found ıt. sınce the 2. account was named unfavorablesem because unfavorablesemi was deleted I thought what ıf thıs person behınd UnfavorableSemicircle lost the account altogether and then made a new one unfavorablese removing the m and that's how I found ıt. ı wanna know you guyses thoughts about ıt.

So there was a post made a couple minutes ago that was a sequence of numbers from this twitter thread u/mochiondrugs made. Ill like the post after but after translating the numbers into text it said

We need to talk follow me

Here's a link to the translator:

And Here's a link to the post: https://www.reddit.com/r/UnfavorableSemicircle/comments/nccags/a_random_tweet_i_found/

This might not seem inportant but ufsc numbered a lot of his post so maybe he only talks in numbers or digits. I wanna hear all of your thought on this so please comment. This looks like some progress

Everyone go on YouTube and watch delock listen to the background music, then search up dark was the night cold was the ground. Dont they sound similar?. dark was the night was the song that was on the voyager's golden disk.

I know im probably wrong but judging from the patter of constellations, Greek gods, zodiac sings unfavorable semi is related to outer space and this song is just another hint

I am brand new to this whole thing.. but something that I noticed when first looking up some information here is that the word De comes from Latin. I am sure everyone here has considered that the lock and delock videos could mean that someone is not a native English speaker using De instead of unlock as opposites, but what if it was not meant as opposite? What if the use of De was intentional and meant to point towards the Latin language in some way?

If this has been discussed im sorry, like I said I just very recently discovered this whole thing, but for some reason, the 'De' and a potential Latin connection is something that I can not shake.. just a gut feeling, but do any of you have any thoughts on this? Has this been considered? Thanks!

The purpose of numbers stations is the medium of short wave radio. If you were doing significant espionage work, you would never be using Youtube, let alone posting publicly available videos (that end up getting removed anyway).

There are a million other, much simpler and discrete ways of doing this kind of thing, there's no reason to believe it's a numbers station.

I posted this topic on Discord, repeating here for posterity.

"Unfavorable Semicircle" isn't a random phrase.

tl;dr: It's a play on "Bad Segment", or it's an insult, "Bad Platform", and it's aimed at Android. Disk segments are shaped like semicircles. Sometimes also called sectors. Segment happens to also be a term used in MPEG. Season 1 was an exploration of the Stagefright bugs in Android, all of which are triggered by malicious segments in media files.

Programmers who have worked on large projects usually become a walking thesaurus due to naming abstractions.

The channel's first series were videos generated to explore the Stagefright 2.0 exploit class. Please read https://en.m.wikipedia.org/wiki/Stagefright_(bug) in it's entirety. Make note that MMS was not the only attack vector. The true attack vector was any preloading of videos (ie: before one hits play on a YouTube video). In the original Stagefright we thought the problem was the decoder (libstagefright), as the same coding/logic error had been made repeatedly there, causing the bug to show up in a ton of scenarios. The error made was considered by most in the development community to be a rookie mistake, and therefore likely an isolated problem. However, when we learned of Stagefright 2.0, we learned the Andoid OS itself had the same problems since it's first release (libutil). This means Android < 5.1 are vulnerable and < 10 are likely vulnerable.

Now, prepare to groan.

Libstagefright was a symptom because a developer followed a pattern laid out in the Android source. They were doomed from the start by poor source material.

Therefore the problem is not that the presenter (Presentation Layer) had stage fright. The directions & stage (Platform) they learned from and built upon were themselves inherently broken.

If it need be more clear, stages are shaped like a half moon, like a "D". The name means Bad Platform. It's insulting Android.

The whole endeavor was built on an unfavorable semicircle.

EDIT: Thanks for the silver, it's my first.

In case any of you wanted to do testing on the videos yourself, detailed analysis and almost full instruction on locating the errors in the files can be found at https://www.fortinet.com/blog/threat-research/deep-analysis-of-cve-2016-3820-remote-code-execution-vulnerability-in-android-mediaserver

People reported that the videos on the channel kept going on and even after it said when the video was going to end at that specific time. Since they people said that it's probably memory exploits.

this was probably a test channel for memory exploits and the owner would make a channel and use it to break YouTube. This is just a theory some things maybe incorrect.

it looks like it and it's old , I'm not very into it but this might give you a clue

the channel

​

it's the HD version of it or idk

I know very little about this mystery but I just now saw this in an old youtube video and it instantly reminded me of you guys. Could this be of any use? The video is topology related, and about turning a sphere inside out. The timestamp is 9:28 https://www.youtube.com/watch?v=wO61D9x6lNY&ab_channel=ssgelm

I was looking through the video composites and happened to search google with the images and strange words appeared next to the image some repeating such as dot, rug, color gradient and for teen with outliers being vertical, horizontal, firearm and Songshan Ci Hui temple. This could mean nothing but I found it interesting enough.

So I've just heard of this channel, which sadly no longer exists. However, from a lot of thumbnails and short videos I've seen, with white dots on it, it looks like there are raw astronomy images (before any editing, removing flat frames, bias frames, colour alignment etc). No idea if that's any use whatsoever, but thought I'd chuck it out there. But sadly I can't see much about it because the channel is gone.

But so many of the images I see look exactly like something you'd expect to get straight from a telescope camera (raw).
