I am using FFMpeg for simulation. The input is a series of 1024 x 768 jpegs, and I am making them into an MPEG2 file. I can't work out how to change the chroma sub-sampling between 4:2:0, 4:2:2 and 4:4:4 I use something like: ffmpeg -r 24 -i .\1\jpg\flight_sim%3d.jpg -b 8000 -me zero -y test.mpg but I can't find a command line argument to change the chroma resolution. Thanks
