What version of Premiere Elements are you using on your Mac computer?
Did you apply the Difference Matte write up that I posted? Many Premiere Elements Windows and Mac users have reported using the technique described for Green Screen.
I have not heard of any alternative for the Premiere Elements Mac user other than go Premiere Elements Windows.
Please review and let us know the outcome.
Just not to take anything for granted, I ask "Have you reviewed your green screen prep work?"
Videomerge, by the way, should give you great results, if you've got a smooth, evenly-colored background.
But you do have to define the background as your key color -- which you've apparently not done.
Thanks Steve and A.T., difference matte turned out to work perfectly. Found the button for setting the difference layer video under applied effects on the right side of the screen, that made all the "difference" in the world.
