2 questions :-)

Alright guys, I've been using Vegas Video for about 2 years now and I've yet to figure out how to do two things that I've been desperately trying to do for a couple unique projects I am involved with....

First....this is definately the easier of the two problems, but is there any way in Vegas Video to reverse an audio track? Like so a song plays backwards? The only way I can think to do it would be to put a senseless video clip on top of the track im trying to reverse, render it, make a new file and put a velocity envleop on it (because you can't apply those to just audio tracks)..and then re-render that file as an MP3 so that you only are left with the reversed audio clip...but is there an easier way to do this?

Second....this is the toughy that's had me stumped for a while....I'm attempting to make a 3-D video for a presentation I'm working on.....specifically Analglyph (red and blue glasses)....I've tried different things and come close with results and have been able to create depth with Vegas Video (certain objects in frame appear to be in the very back of the computer monitor burried deep inside), but haven't yet been able to perfect it to the point of having things pop out at you.....if anyone is fimiliar with these techniques, any advice or words of wisdom would be appreciated :-)

Thanks guys!

For the first question... Vegas Video 3.0 came with Sound Forge Studio I believe. I'm not sure if that version of SF has PROCESS-REVERSE, but if it does you just need to use EDIT IN SOUND FORGE from within Vegas and reverse it there and bring it back into Vegas.

For the second question.... I've seen a system that did exactly what you're talking about. Not only could it shift the distance between objects but it could move the objects out of the screen so they almost on the tip of your nose.
What controls your perception is the point of convergence, your brain calculates that from the angle between the eyes I think.
In the case of a monitor the eyes are focused on the screen, it is the point of convergence so the brain sees everything as being 'inside' the screen.
I'm only guessing as to how this system managed to change that. They did have an expensive screen that was probably very reflective. Possibly they were creating a virtual image, forcing the point of focus and hence convergence in front of the screen. It was a polarising system that used two projectors with matching filters.
Whole show is a tour through the universe, very impressive.

If you're keen to know the answers I think I've still got the contact details for one of the scientists who specializes in 3D imaging.

For the 1st, Velocity Envelope only affects the video track.

For the 2nd, are you shooting the original footage with two cameras simultaneously?
