Hmmm. Let me ask these questions then:
* what is the file format that Cinelerra is most robust with?
* what file formats do the "pros" use? Is there a wide range, or is the
scope restricted?
* So how does Cinelerra work: when I see an image in the compositor, for
example, is that a rendering of a so-called VFrame? And how is that
VFrame produced - is it produced "on the fly" from the underlying file
format, is it rendered from a small look-ahead cache produced from the
file reader, is the whole file converted to a list of VFrames which are
then  just rendered as needed, or is it "none of the above"? I'm really
stuck on the fundamentals.
