[MPlayer-users] v210 -> video filters -> v210

[András Bohó]

I see. And how can I convert 444P back into v210?

I am trying this:
ffmpeg -i v210_720p_444p.avi -vcodec v210 v210_720p_v210.avi

I would gladly use ffmpeg alone actually but I dont find even the most basic
filters in it, like hue/saturation/gamma change etc.. so temporarily this
444P format would be sufficient if I could convert it back..

Thanks for help.
