I disagree.  The preferred form of modification for these movie clips is
the original lossless data, or the AfterEffects, etc. data, and so on.
If the artists modify the clips, that's what they really use--that's what
makes it source.  If we want a synthed song to be 20BPM faster, the musician
isn't going to use the PCM data; he's going to modify his source.  The fact
that it's too big to store in the repository for other people to use doesn't
change that.

I can't apply filters to Vorbis files just as well as WAVs.  They're lossy,
which means that my filter is operating on lossy data and--depending on the
filter--the result will be lower quality.  Many times I've asked coworkers
to resample sounds, for example; I can't do it myself because I'm not willing
to decode, resample and re-lossily-encode the data for quality reasons.

I agree with the practical issues you're talking about.  I often create
stylized text images with Photoshop and don't bother saving the PSD, because
it's easier to just remember how to create it from scratch than to organize
and store that much source.  I do think this is an important and very common
case to consider, but I don't think it's a way out of the source-for-images,
etc. question, because in many of these cases, the preferred form for
modification really does exist, and really is preserved for future modification.
