Help With Velocity Envelope
I understand that by using velocity envelope I can speed up certain parts of a clip?
Here is my problem:
1. I’m filming game footage.
2. I want it to play normal speed when I kill someone, but afterward when I’m done I want the boring running/healing stuff to be fast-forwarded.I add the velocity envelope, and put two dots after I kill someone, and two dots before i kill the next person. I then increase velocity.
I then drag my clip shorter to match the V symbol thing. However… its not speeding up the crap I want it too, it speeds it up and then has me killing the second guy fast as well. Instead of it fast forwarding through the boring stuff it fast forwards through the kills as well.

I’ve never really liked Velocity Envelopes for speed “ramping,” for exactly the reason you list (i.e., it’s not precise enough). Personally, I just snip (press “S” on your keyboard) on the frame where I want the speed change and then CTRL+Drag and squish the clip that needs to be faster (up to 400%). If I need it even faster, then I’ll use a Velocity Envelope to bump the speed up even more (up to x300% or 1200% total), but I rarely “ramp” it and just kick the whole thing up with a flat envelope.

The velocity envelope would appear to be useless or at least very limited in its usefulness. If you change the speed of a section it of course chsnges the length of the video. But the envelope does not adjust to stay with the speed adjusted part so that other parts are effected as well. You can kind of work around this by splitting out your section to be adjusted and then change its speed (but without ramping)You then change the length of the changes video to match the ‘notch’. But there seems to be no way to adquetely ramp the change.

Thanks for the help. I’ve figured out how to snip clips and am now satisfied! 🙂

Good deal. Yea, “speed ramping” sounds cool in principle, but even when you see it in commercials or films, the “ramp” always seems to be zero frames anyhow. Still, always great to have options!
