The Apple Music Album Motion Artwork is an animation loop based on the album cover, which plays on certain iPhone, iPad, Mac, and Smart TV devices
The cover must always be visible, and it has to be a seamless loop (the cut should not be noticeable).
It cannot include any extra images that are not part of the album artwork.
Deliver motion art in the H.264 codec file format.
When delivering a 3:4 motion art asset, provide full-frame content.
Do not crop a 1:1 video into the 3:4 safe area—submit native 3:4 motion art, not repurposed square content.
