Velocity envelope question

OldTimer wrote on 2/8/2003, 5:32 PM
I tried this tool for the first time the other day but it didn't work the way I expected. I took a clip exactly 10 seconds long then pulled down the control until it said 50%. The clip then played at half speed correctly as expected. I had also expected the entire clip to now play for exactly 20 seconds, but it didn't. Why not & can I set things so that the total time played will come out to what would be expected?

Keep in mind it's twice as long in duration so try dragging the right side of the clip to the right until you see the little notch.

To elaborate on what Randy said, we can't automatically stretch the clip when the Velocity envelope because the 0% case is undefined (infinite length) and the negative cases, well, just as bad. If you want to change length and rate at the same time, then Ctrl+drag an edge of the event.

I did not know that Dennis, thanks! Is there a way to tell what percentage rate you're at?
Thanks again,
Randy

Not using that method. However, you can also adjust the same rate in the event properties dialog, using a percentage. This doesn't auto-stretch the event though (oddly, it does for audio events). Event rate is in addition to velocity envelope, they layer on top of each other.

Thanks Dennis.
>(oddly, it does for audio events)< Perhaps this is due to the "retain pitch..." option, no?
Thanks again,

IF it stretches the audio event, couldn't you enter a % for each, then drag the video so the clip duration matches?

You could, except the audio stretch dialog uses semitones/cents instead of %, and also the properties page method doesn't bring along grouped video.

So, you can do it visually, and then check the percentage in the properties page, or do it numerically and then snap to the media end mark later.
