Motion Maker templates support video loops as backgrounds for most templates.
We recommend .mp4 videos under 10s in length, seamlessly looped. You can make your own video loops, purchase them from stock sites like Videohive.net, or commission them from any motion graphics designer.
You cannot import your own audio or 3D models to Motion Maker.
If you want to make an app with custom audio, or 3D models, you can request a custom order.
This year, we will be adding asset packs to Motion Maker so there will be more graphic and audio options to choose from. If you have any requests or recommendations, please leave them in our community forum.
