Yes, it seems to prefer a video ;)

One challenge I ran into initially was that I did graphics for 1080, but with 720 clip underneath, it cropped the menu.. Ended up re-encoding the clip to 1080 instead of rebuilding all the menu elements.

If you have that same intro at that resolution, or, can encode it at that, I'm sure it'd be better than the converter I used. That, or I can rebuild the menus to be @ 720 size for the project. Was really a version .01 kind of thing anyway to see if it was possible. ...was excited to be able to do it at all, and see that it actually worked as intended.
