Hello,

I'm trying to help one of my Linux users with a rather frustrating
problem: Basically, Cinelerra handles keyframes just fine during
preview, but behaves erratically when rendering. E.g. a fade-in from a
particular track works fine in the preview, but in the rendered result,
there is no fade-in any more -- the clip starts smack bang.
This behaviour seems quite unpredictable; most keyframes are processed
OK, but especially the ones added later in the project have a tendency
to act up.
It appears that the trouble started  when the user attempted to  mute a
track from a particular point onward. Instead of a mute from that point,
the video track completely disappeared in both the preview and the
rendered result, although it remained visible on the timeline.

The project itself is best described as a long music video; the base
material is a 30-minute piece of music (WAV format), to which three
separate DV video tracks are added. One track in particular contains
quite a lot of fades and copy/pasted video fragments, which are
processed using a handful of different effects.

The project's XML file is found here, if that's any help:
http://www.linetec.nl/linux/oerknal4.xml

Does anyone have any idea what causes these problems, and if there's a
solution or workaround? The hugely frustrating thing is that things only
go wrong during rendering, making it practically impossible to complete
the project. The preview may look perfect, but only after 90 minutes of
rendering can one see whether this is also true for the rendered video
file. So far, the result has not been acceptable. And with each failed
attempt costing 2 hours (1,5 hours of rendering and 30 minutes of
painstakingly checking the result), frustration is mounting ...

Anyway, I hope this is still simple user error, or at least something
that can be fixed. As always, any help is appreciated.

Thanks in advance for any advice, best regards,

Richard Rasker
