any good audio/video editing apps in macports?

[Jim Graham]

For those familiar with it, I'm looking for some video editing software,
preferably as similar (in capabilities) as Virtualdub on 'doze, something
that can edit by frames, join, split, convert, filter (de-noise, resize,
crop, de-interlace, adjust frame rate to match audio (mainly for vid
caps), and so on)....

I'm also hoping there's some audio editing software that can do things
like work on either channel of stereo, merge stereo into mono,
add/delete/edit audio chunks, combine audio samples (in series), blend them,
modify volume level (overall or normalize), etc...  An example from the
'doze world would be Soundforge (except it's not a free app).

Anyone know of anything that'll do either or both of these in macports?

Thanks,
