> Also video that is 720x486 and captured from analog source often can be cropped down to 720x480 at 4/3 by removing the first 4 and last two lines. You may have a better looking result if you start your filterchain with crop=720:480:0:4 before scaling.
I have not done the
crop=720:480:0:4 before scaling before
