Seems like a great way to get your account closed for abuse!
I've been uploading 2-3 hours of content a day every day for the past few years. On the same account too.
I have fewer than 10 subscribers lol.
It's just recordings of myself when I'm doing deep work. I use OBS to stream my computer screen and a video recording of myself (mostly me muttering to myself).
It helps me avoid getting distracted (I feel like I'm being watched lol) and it's also interested to check back if I want to see what I was working on 3 months ago.
All the videos are unlisted or private.
Also, any potential issues with Google having access to proprietary code? I know the chance of any human at Google interpreting your videos is near-zero but still
But I guarantee there is some clause in the ToS that this project violates.
something like this but far more mundane
Others in these comments have also suggested steganography in both the video and audio streams. The problem with that is that when you retrieve a video from YouTube, you never get the original version back. You only get a lossy re-encoded version, and the very definition of lossy encoding is to toss out details that humans can't (or wouldn't easily) perceive, including ultra-sonic audio.
Or better yet, the file could be one third the size if the human says the numbers 0 to 7.
Some forms of DRM are already essentially this, compression - and even crappy camera recording from a theater - resistant DRM that is essentially stegonagraphy (you can't visually tell its there) exist.
EDIT: "compression resistant watermark" is a good search phrase if anyone is curious
in other words; if YTs compression was affecting it so badly that it prevented the data from being re-read, wouldn't that compression scheme render normal video-watching impossible?
