Final Cut Pro – Setting Just One Keyframe from the Timeline
The Viewer isn’t the only place you can set keyframes.
Using the Add Motion Keyframe button in the Canvas sets fourteen different keyframes. What if you want to set only one type of keyframe, instead of all fourteen?
1. Select a clip(s), and position the playhead where you the keyframe to appear.
2. Control-click the Add Motion Keyframe button and UNcheck Keyframe All to deselect everything in the menu.
3. Control-click the Add Motion Keyframe button again and select the type of keyframe you want to create.
4. Ta-DAH! Notice how only the type of keyframe you selected has been applied to your clip(s).
