32 -pix_fmt // pixel_format
36 -acodec // audio codec
37 -ar // audio samplerate
43 ADD 1 FILE myfile.mov -vcodec dnxhd
44 ADD 1 FILE myfile.mov -vcodec prores
45 ADD 1 FILE myfile.mov -vcodec dvvideo
46 ADD 1 FILE myfile.mov -vcodec libx264
48 For the above formats have already provided high quality default parameters.
