OK, there is the facility to *nudge* the audio to sync with the video. But
any nudging starts off on the wrong foot because the Audio Offset is
operating and so while you think that the video and audio are in sync on the
timeline the final render will be out of sync because the Audio Offset is
ignored.
If my understanding of things is as I just mentioned then the use of the
Audio Offset is a waste of time and one should simply edit a file with Audio
Offset = 0.000 and only use the Nudge facility to synchronise video/audio.
Am I misunderstanding things?
There are systems where is certain delay in audio playback path. On
these systems Audio Offset is needed to compensate this delay. There
are systems where this copensation is not needed. The intended usage
of this setting is during setup of cinelerra.
Nudge is editing tool. User can use it to synchronize audio/video.
Cinelerra assumes that audio and video start exactly at the same time.
With digital video this assumption is not always true.
Thanks for the reply, Einar.
Yes, I understand all this. What I don't understand is why this has to
be an affliction to Cinelerra because whatever video I watch thru VLC,
MPlayer, xine, kaffeine has perfect sync. But what is most puzzling is
that - and I repeat this once again - I created 4 parts of a series
which are perfectly in sync, whether I play them in Cinelerra or any of
the players, but this last one just won't sync once it hits Cinlelerra.
Well, sorry, not quite correct: I can get it to sync in Cinelerra using
the Nudge facility but when I render the file this nudge setting is
absent and I get a mouth moving with the sound coming after the mouth
has moved on to better things :-) .
I have looked at many tutorials on YouTube re Cinlelerra and I cannot see
any of them covering this matter. (And the manual is more confusing than
helpful in many instances - it seems that it was thrown together just for
the sake of producing a manual to be read by someone who already knows all
about Cinlelerra.)
Cinellerra is a powerful tool. Powerful tools are not simple to use.
Cinelerra is not very intuitive tool. The manual is quite good, at
leat it exists. I recommend to read the manual at least twice and
refer to it again during usage.
