Yes.

As far as I have understood, Audio Offset is for _calibration_,
and nudge is for _correction_.
Thanks for the response, Herman.
Yep. As I mentioned to Einar, I wonder why it afflicts Cinelerra when
all my tv programs, videos are all in perfect sync - or, at least, so
close to being perfect that any difference is not noticeable.
Calibration is per computer/installation, and correction is
per project/format/track/clip.
Now, if only there was a way to reliably calibrate audio/video
synchronisation on a computer! I'd like a cheap gizmo, let's
call it a Synchrophone, that has a simple microphone and a fast
rate low-res sensor (one monochrome pixel might do).
I like this idea! :-) Like a clapperboard but only in the form of software.
You sound like someone who knows something so can you explain this,
please :-) .
In the Cinelerra manual, page 23, instructions are given on how to
calculate the audio offset. The part which really has me confused is this:
"Play the timeline from 0 and watch to see if the gradient effect starts
exactly when the audio starts."
When exactly does the audio start - is it when the audio level meter
appears on the right-hand side of the Compositor window or when the
actual *sound* is heard (to match the appearance of the synthesiser)?
