Re: Dammit- What am I doing wrong?
- I agree with Schlomo's advice to use Mpeg Streamclip, its great for
converting various sorts of mpegs, can be very useful if working with
native hdv mpeg2 transport streams for example, though this is needed
les these days since more editors support hdv.
I dont quite agree with his explanation of whats caused your problem
though. Demuxing audio is definately needed but if your stuff is out
of sync, its not a question of VisualHub failing to do that, but
rather making a mess of doing it.
This could be because of some bug in VisualHub or it could be due to a
quirk in the sony mpeg format from that camera, or it could be due to
a mistake with settings. For example if the framerate of your original
footage is not the same as what its getting converted to, this could
caause audio sync issues. If visualhub is reading the sony mpeg file
and is being told the wrong framerate or audio sample rate of the mpeg
file, this could also cause the problem. Either way its probably
easiest to try Mpeg Steamclip instead, depends how much 'fun' it is to
explore the root cause.
Which camera is it out of interest?

- Cool! Thanks, Schlomo. Turns out, I downloaded that (MPEG Streamclip)
a few weeks ago, and didn't use it. I'll give it a go. -- Chris...
- Thanks EVERYONE, because MPEG Streamclip cleaned it up stupid-easy. It
made the file a little fatter, so I'm smooshing it back down in iMovie
to see if that finishes it up nicely, but the lips match the audio,
which is helpful.
The camera, to answer yourself Mr. Steve Elbows, is the Sony DSC-T9
(we're giving away $25,000)
- Thanks for the info. The spec of the video is as follows, framerates
seem slightly non-standard so that might explain why some apps didnt
handle sync properly, not that it matters now as you've got a solution
MPEG Movie Mode: MPEG VX Fine (640 X 480, 30 fps) with Audio, (MPEG VX
Fine Requires Memory Stick PRO media) MPEG VX Standard (640 X 480,
16.6 fps) with Audio, Video Mail (160 x 112, 8.3fps) with Audio
