Help with converting to mp4 for my iPod?

Yesterday I downloaded Moyea video converter to convert swf (flash) files to mp4 for my iPod. The converter works fine and the videos come out in excellent quality when I try playing them on my iTunes, but when I put them on my iPod it only played audio and showed a black screen.

Does anyone know what I might be doing wrong?
