👋🏻 Hey @Hasse Finderup — welcome to Figma Forum, and glad to hear you're enjoying Motion so far!
Thanks for sharing this. What you're seeing is expected behavior at the moment. When exporting from Motion, video fills used as backgrounds are captured as a static frame rather than playing video in the export. Our product team is tracking this as a feature request, and the same behavior occurs with any export format when a video fill is involved.
I don't have a timeline to share, but we'll announce any developments here as well as keep this resource updated: Export animations from Figma. Let us know if any other questions come up as you continue working with Motion. 🙏🏻
