i cannot stress this enough, do NOT run the command ffmpeg -filter_complex “nullsrc=s=1920x1080,geq=random(1)*255:128:128[vout]” -map “[vout]” -t 46 -c:v libx264 out.mp4 in order to generate one of these large video files then upload them en masse in order to slow down their servers,

    I quite agree. Don’t do that. Because I tried it, and it doesn’t work.
