Some month ago I needed to do a show for a contest.
I needed to show videos and images, but sometimes I needed to display a timer over de image or video, and I do not have a video mixer.
I've found that if I set a very long fade out time in the background video, I can play another video, small at the bottom with the timer, while the background video continues playing.
In any case I can stop the background video playing another or triggering a SFR cue.
I wish to add this as a feature request too. It could be helpful to have the possibility to have an option to set a video as overlay of anything that's playing in one screen. And it could be perfect if admits transparency with alfa channel.
