I ran into some confusing behaviour of the speed control effect. I've loaded a whole strip of video and applied the effect setting it to a 2x speedup (in two variants - with the default "stretch to the input length" and "Scale to length").
I expected to see the reduced length of strip, but it appears to have no influence on the length. On the other hand, the video sequencer shows that after some frame, the picture doesn't change while marker is moving. Do I have to calculate this frame manually to insert a new video strip?
