Question: I’ve set up more than two Key Frames for a shot. Is there a way to generate Tweens for the entire shot in a single go?

Yes.

1. In the Shot Manager, hold down the [Shift] key and click on the first and last frames for which you want tweens generated. All intermediate frames are selected automatically.
2. Click the [Create Tweens] button at the far right of the top button row.
3. The Create Tween Frames dialog box appears, with the additional frames shown in the Multiple Key Frame Range Display area. A block of red text at the top will also inform you how many intermediate key frames will be generated.
