Issue(s) with velocity
Hi, I keep running into this issue so I thought I’d ask here.
(using Vegas Pro 8)
I sometimes want to show something in fast or slow motion. I have read the help files and pretty much figured out how to do it, except I notice that only the video velocity changes. the audio track just keeps moving along at the same (normal) speed. this messes things up, when I try to return to normal velocity, as everything is out of sync. Plus, I’d really like the audio to speed up or slow down along with the video. Can someone tell me what I’m missing?
Also I noticed that when I grab the velocity “slider” on the clip, if I move it all the way to the top, the max seems to be 300%. Is that the fastest I can go? Is there any way to speed things up more than 300%?
thanks very much,

I believe you would need Sound Forge to streach or shrink the audio to match the velocity changed video when you use a velocity envelope. You can get the results you want by holding the ctnl key and dragging the edge of the video event to shorten it, even more than 300%, and the audio follows using this method, At least with Vegas Pro 10a. Hope this helps, Danny Hays

What Danny is describing is changing the playback rate. This changes the video and audio together for up to 400% (or 4x). This is in addition to any Velocity Envelope you might apply. 400% x 300% gives you 1200% increase. If that’s not enough, nest the project in another project and repeat. As Danny said, there is no way to make the audio playback follow a video velocity envelope. This would take manual manipulation using the Pitch Shift plug-in or by using Sound Forge.
