Magic Music Visuals

I would like to set video to stretch to fill the Magic window instead of having blank areas.

Is there any setting I am missing?

Hmm, well you can use a Scale module to change the X and/or Y dimensions of the video. Or did you want it to always follow the window size, no matter what? If so, can you describe the use case for that?

Yes... I was hoping to have it fit the window size.
My use case is sending it via spout to different apps, where I do mapping etc...
It would be easier to see what the final output will be if all media in Magic was stretched to the Magic windows dimensions... (as an option

So basically you'd like a "fit" or "stretch" checkbox for the Video module?

Yes. I think that would be very helpful in some cases.
