Hi, Michael.
MP4 videos are natively supported in Storyline 360, while other video file formats get converted to MP4 (you can see the list here).
Since MP4 doesn't accept alpha channels, this is not currently a feature supported in Storyline. We are tracking a feature request and will update this discussion when we have any news to share!
