YSK long noise videos cant effectively be compressed and as such take quite a lot of storage space and bandwidth. So if you want to keep the hosting costs of social media platforms low, for example when going public, you definetly wouldnt want disenfranchised users to upload them to your platform. This is the kind of noise you would want to avoid: https://stackoverflow.com/questions/15792105/simulating-tv-noise#15795112
/dev/urandom will supply different seeds for the different function calls if you’re on Linux because it’s pulling from a rotating random number generator. Eventually it will repeat itself if there’s not enough random data being generated from /dev/random to pull from though.
For Windows, instead of hard coding a number as the random number generator, use “time(0)” instead. It’s the number of seconds since January 1, 1970 down to 6 decimal places. It also changes per frame, so your noise should be different than anyone else’s noise. Someone demonstrates it here https://www.youtube.com/watch?v=3jb8NNmooCM but just prints it to the command line.
