still trying to figure out how you edited the plates in The Mythsters Reloaded to say "Mythsters" so cleanly. amazing work
Thanks! Sometimes I get a little ambitious with the visual gags and make them higher-effort than they deserve, but this one was actually much simpler than it looks! Just a video mask with a feathered seam.
You can see the video this effect was done for here (appears at 1:17)
When this effect appears again at 5:43, the seam takes on a different shape because the straight line would give it away.
After those two turned out so smooth, I thought it'd be funny to fully break the illusion when the bumper happens a final time at 6:23. The stop-motion toy cars just become fully cut off when they drive past the seam, making the edit painfully obvious.
