    This does not work.


    ffmpeg -i MVI_3298.MOV -y -filter:v "crop=600:720:270:0" -ss 00:01:14 -t 00:00:09 -acodec copy -vcodec copy ay.mov


    This works.


    ffmpeg -i MVI_3298.MOV -filter:v "crop=600:720:270:0" -ss 00:01:15 -t 00:00:06 -an -vcodec h264 ay.mov


    I want to crop the video without transcoding.
