Velocity Envelopes

JackWhite wrote on 10/4/2004, 12:55 PM

If I want to speed up and slow down an event, I know that I can either use v envelopes or just drag the end of the event in. I would like the sound to speed up / slow down with the video - can I do this using velocity envelopes?

Thanks.

Sorry, another question. If I speed up the clip using velocity envelopes, the clip lenght stays the same and repeats itself. How can I easily stop the clip repeating itself? Can't wait for my Spot book to arrive!

Audio will not change using velocity envelopes. If you want the audio to also change, you must use the CTRL-resize method.

When you speed up a clip you will notice a little "notch" appears in the event to indicate the point where the event now finishes. It will either start looping at that point or it will display the last frame (depending on the setting you have applied to the clip (right-click event).

Just drag the right edge of the event back so that it snaps onto the "notch" and it will stop at the end.

Thanks Liam, I can see the notch now! It's a shame you can't add a velocity envleope to the audio as well. Does anyone know of any other way of making audio match a video clip that has been sped up and slowed down?

If you’re not trying to accelerate/decelerate within the events, say by adding velocity envelope points, why not just use the Cntl-drag method to resize both video and audio at the same time? You could also uncheck “Preserve pitch when stretching audio events” under Options > Preferences > Editing if that’s the effect you’re after.

Thanks JL. I was hoping to speed up an event and then gradually slow it down to a freeze frame.
