How to Backup VCD?

The U and V channels of YV12 video are half the width and height of the Y channel. The frame size will need to be mod 8 to ensure that the U and V channels are mod 4. This shouldn't be a problem with a 352x288 frame size which is mod 32 in width and height. But if you cropped the frame before the sequence you'll need to adjust your cropping to leave at at least mod 8. Or crop later.
