Encoding 4:4:4 in h264/h265
I’ve been trying for a while now to find a good solution for making high-quality video files, for local playback, to display detailed motion graphics. Basically I end up with problems everywhere because of the sampling rate. Almost all available formats will deliver in 4:2:2 which is not good enough for my purposes.
So as I understand it, 4:4:4 encoding should be possible in H264, but I can’t find a solution for doing it.
Will FFmpeg do it? And if so, could someone point me in the direction of the correct command? -

I was looking for the same thing and tried several ffmpeg GUI. The only one I could render 4:4:4 h264 was myffmpeg.

the x264 profile command for this in ffmpeg is fairly straight forward to implement off of CLI – it is;
-profile:v high444
You will of course need to set your bit rates max/min and presets as desired but this profile setting will output a h.264 at 4:4:4.
