Speeding up video

tdillard wrote on 6/4/2004, 12:56 PM
I know how to do a velocity envelope, but I believe that will only go up to 300% or so. Is there an easy way to get my video faster than that? I'm making a vacation video and want to really speed up our packing and loading sequence, maybe put it to the Looney Tunes theme or something. When I speed it up and render to an MPEG with the intention of bringing the MPEG into Vegas 4.0 and speeding THAT up, I get the MPEG at the original speed.

Also, I was wondering if there's a way to speed up the video as fast as I want without going through the render process.

Thanks in advance!

do velocity envelope, AND right click the media, choose Properties, then select Playback speed, set it to 4.00
That will work.
Don't ever render to MPEG and then plan on bringing back to Vegas. Render to avi/new track, THEN speed it up. Rendering to MPEG costs too much in quality. MPEG is a delivery format, not an editing format.

"I get the MPEG at the original speed."

It sounds like you were speeding the video up by using the rate slider (little yellow triangle). That only affects preview speed, not the speed of the finished video.

If you combine 300% velocity envelope with 4x playback you can speed the video up 12x. Render this to a new DV .avi file and then you can bring it back in to speed it up more. I've sped stuff up over 1000x this way.

No, I was using a velocity envelope. I took just the footage I wanted sped up, increased the velocity to 300%, rendered, and brought it back it, where it was original speed again.

I'll try your suggestion, it looks like it'll work just fine.
