I've built a few full width lower third bars in GT Title that fly up from the bottom on transition in, and fly back down on transition out. They look and work perfectly in GT Title Editor.

In vMix, when applied as an overlay, they fly up properly, but the TransitionOut animation is not obeyed and a plain fade is executed. I realize that you can right click and select transition out, but this should also happen when the overlay is deactivated.

With stock titles, the out animation is obeyed and performed when deactivating the overlay.

I'm about to extract and compare XML of a stock title we use that works with the XML of the ones I've created to see if GT editor isn't writing something that needs to be there.
