I mentioned in another thread that I find Velocity Envelopes tricky to work with and tend to avoid them.
Here's the particular problem I have.
Suppose I have a video clip. At point A I want it to speed up and at point B I want it back to normal speed.
I want to match this to music which has crucial beats at point X and Y.
(Without any time stretching points A and B are further apart than points X and Y)
I want to sync point A on the video with point X in the music, and point B on the video with point Y in the music.
Using the method of splitting and Ctrl-dragging the middle section of the video, this is easy, though the change in velocity is immediate (not pretty).
But how would I achieve it using velocity envelopes?
