Note: This tutorial uses an old version of KeyTweak. The new version has a much nicer interface but you also find the old interface in it if you click on the "global mode" button.

In this tutorial you learn how to use our After Effects tool KeyTweak to quickly modify any keyframed property. Just modify a few keyframes by hand and KeyTweak will automatically modify the keyframes in-between accordingly. While properties with hundrets of keyframes are usually a nightmare to edit in After Effects, this is easily possible with KeyTweak.

In particular you learn how to use KeyTweak to

• modify drifting tracks
• correct rotoscoping errors
• make non-uniform mask expansions
