The audio/video locking thing has bothered me in the past, since even an
accidental move of either can cause a slight lack of sync, which is hard
to spot and is nevertheless annoying in the final render.
It's interesting that this issue isn't handled by Cinelerra itself. In
the past I've thought about writing a script fixing this in Perl, which
makes the necessary time calculations on the EDL file (directly) for
spotting unsynced audio/video, issues warnings and suggests correcting
these things. I never got to that, because I thought this issue will be
solved within Cinelerra itself pretty soon.
It seemed wrong to me, that the process would be a text application
saying "Channel X doesn't match channel Y by Z seconds at time T. Do you
want to correct?". It would be so much more sensible, that an attribute
of the sound track would indicate that when the sound is taken from a
video track, it should always be synced.
Want to lock video and audio together? Then Cinelerra isn't
the tool you want.
