MP4 does not populate on OS. Only thumbnail (PNG)

Manifold Support Questions

I set up a claim page for an mp4 with a png thumbnail (ERC-721).
After minting, the mp4 does not show on OS. Only the thumbnail. I click on the thumbnail and it just enlarges the thumbnail instead of playing the MP4. halp.

OpenSea will only display the MP4 if it is < 100MB.
