Seems to work as expected for me. I drag the png to the track above my existing video. When you say paste I’m wondering if it is inserting into the main track and perhaps overwriting/replacing the existing. If your general LumaFusion background in settings is black then you’d get your png on a black background.
Thanks Mark. Truth to tell, I never noticed the background option. However, it seems to go through the entire spectrum from white to black but doesn’t seem to have a transparency option. What am I missing?
