They had way more animation budget than normal in the new movie and they went nuts with it in terms of onscreen motion. So far, making this work in 3 MB has been easier than I expected.
This footage happened to create a pretty good misdirection that helps it loop.
The movie has a lot of shaky cam shots. I ran this through a motion stabilizer to loop it.
Several disjointed shots cut together. Pretty easy.
Another motion stabilized shaky cam shot.
