Convert video for iMovie with ffmpeg

You need to include the argument -pix_fmt yuv420p to generate H.264 content for Apple software/devices, and a bunch of other decoders that don't handle yuv444p.

ffmpeg -i input.avi -pix_fmt yuv420p output.mp4

Apple added ProRes support sometime in late 2014 since iMovie 10 you can use follow code:

ffmpeg -i input.avi -c:v prores -c:a pcm_s16le output.mov
