Hi I know you can assign, keyframes for the brightness of a movie and adding fades, but can you use keyframes to adjust the speed of a movie? For example, lets say I have a 1:00 min movie and certain parts I want to speed up and speed down, is it possible to do this by seeing an enevlope and adding a keyframe when I want to make the movie faster and make it slower?
Yes. It's called Time Remapping: Change clip speed and duration with Time Remapping
