Um could you put that into human readable form? Where are you seeing
cropping? QuickTime plays this at the correct ratio 16:9. It is ffmpeg that
is going by the SAR instead of the DAR. So I guess my next question is
should we always follow the ar of the DAR because it is the actual ar of the
video or...?
