video sequence editor compositing

Hi guys

I have a png image sequence rendered with a transparent background w RGBA channel enabled.

I am trying to combine this with the normal grey Blender background, rendered as a plain image of equal dimensions and also with RGBA enabled.

In the VSE I am selecting the image sequence first, the background image second and adding an alpha over channel. I’ve tried reversing that, as well as playing with the ‘blend’ functions under the ‘edit strip’ options.

I can’t get the two to combine, very annoying. Any help appreciated



Loose the effect strip and change the top strips blend type to alpha over.
