I hope anybody is familiar with AF. I am trying to do effect to my video but I have no idea how I can make it let say in timeline 10 second after starting for period 5 seconds? I really can not find command for that. I only can do effect which affect to all video or from starting to some point. But how to choose only part of video from x seconds to y seconds? How to make for example that video will be at 2x times speed in period 5 seconds after starting for 10 seconds?
Select the layer then go to LAYER > TIME > ENABLE TIME REMAPPING. Then open the layer in the timeline and you'll see Time Remap effect. Here you can add keyframes and change the time - consequently allowing you to speed the clip up, down or pause. Hope this helps
