This is pretty third grade, but what does that do?
It is an export option in Kino and the explanation in the docs isn't enough for me.

If context helps, I am going through some documentary footage, the kind of "five good minutes of footage per one-hour tape" stuff. What I like, I will export in raw DV to edit later. So I'm obviously interested in keeping as much video (and audio) quality as possible.

Thanks,

The developer answered this for me after a day or two. It has to do with resampling the audio so that the bitrate is congruent with the projects' audio, or not and leaving it at a possibly different bitrate.

...added just in case there's any other Kino users here (I can't be the only one :)
