It looks like an opportunity to improve the error message?

No, there is none, however some codecs&containers provide more meaningful
errors and the FAQ contains some recommended parameters, for a few platforms
(iPod, PSP) and codecs (MPEG4, MPEG2).

Besides Reading The Fine Source, you may find in the multimedia wiki, or in
Wikipedia which codecs (and under which restrictions) accept the containers.
