So he said not to upload a video generated like this?

ffmpeg -filter_complex "nullsrc=s=1920x1080,geq=random(1)*225:128:128[vout]" -t 46 -c:v libx264 out.mp4

Got it

ffmpeg -f rawvideo -video_size 1280x720 -pixel_format yuv420p -framerate 30 -i /dev/urandom -ar 48000 -ac 2 -f s16le -i /dev/urandom -codec:a copy -t 5 color-noise.mov
