How can I replace my album cover/artist photo with a video in Apple Music?

There is now an option for Apple Music to add "Artist Motion" to your Artist Page or "Album Motion" to your releases on Apple Music. This is dynamic artwork in the form of short video clips that can be used instead of a profile picture or cover.
​
If you are interested, please read the following guidelines carefully and send us the required files to [email protected] and we will take care of everything else:

​Note: Please follow the guidelines exactly, because Apple only accepts files that match the guidelines. The file must not be larger than 4GB and must be rendered in Apple ProRes 422, 422 (HQ), or 422 (LT).
