I have two video files (xvid) and they have different frame size (640 x 352, 624 x 352). Because of this, I cannot join them and make one avi file (to fit them into one DVD). I tried to join them at virtualdub. I initially tried to find a joining software (like avi joiner or quick avi joiner). But, they either require same frame size or did not accept xvid format. Please let me know how to change the frame size of one video file to match to the other.
My advice would be to not actually join them. Instead use AVISynth to join them on the fly. Basically you would want to add black bars to the side of the 624x352 one. Otherwise you would be stretching it horizontally.
