Can anyone tell me how to do a gradual speed up in Vegas. Not the control+ time shift to shift the whole track, but to start a video off at like 90BPM and then end it at like 100BPM. If Vegas can't do it, do you know a program that can?

acid?

Hi. You should use the Event Velocity Envelope. Click on Insert->Video Envelopes then choose Event Velocity. Locate the two points that you want to increase BPM from and to then go from there. There are tutorials online as well, check on youtube for Vegas Event Velocity Envelope. Cheers

That doesn't change the audio though. I need the audio to speed up as well.

group the audio to the video. then change it.
