Hi there, Roberta!

FLV videos with alpha channel transparency are supported in Storyline 360 Flash and Articulate Mobile Player output but not HTML5 output at this time.

We're monitoring requests for transparent video support as folks transition from Flash-based videos, so I'll absolutely notify you of any changes! For now, here is a neat community idea.

Let me know if there's anything else I can do!
