Since you’ve got the technique figured out as to how to do this, could you run the test on the same videos my son did, to verify his results? He asked whether I wanted him to upload the videos so others could test but I thought it would be better if somebody else did it from scratch so there’s no question about whether anything was done to alter the files.
It seems like there is a time period - between the time of this post and the time that Joachim ran his test - when somebody let this AI company know they needed to change something on their website. If that is the case this is bad, bad, bad and Congress should subpoena the communications to see who did this AI generation.
