During production on a episode or film, it is done through a process called Progression Reel.
It shows how the film is done from one stage to the final version.
Most of them simply show the differences from the storyboard to the final show. However, some of them show the different types of animation that's used in the process (eg. Layout and animation)
- On the progression reel for Trouble on Planet Wait-Your-Turn, if you skip it, you'll see the last few seconds of the reel from The Cheating Scales of Bullamanka.
- To date, the Lyle progression reel is the only one that only contained vocals with no sound effects or music.
- The last few seconds for The Amazing Carnival of Complaining was only in one still. It's possible there was no storyboard action for the rest of the scene.
- Jonah: A VeggieTales Movie was the only DVD that only contained more than one progression reel.
