ChromaKey, Green Screen Key, and Blue Screen Key are not offered in the Mac version of Premiere Elements 14.
Have you looked at the Difference Matte key for your green screening Premiere Elements Mac projects.
There are those that continue to continue to promote the Premiere Elements Mac Videomerge effect for green screening purposes. Videomerge is not on my preferred list as a Windows user. (It is in Premiere Elements Windows also.)
Have you used Premiere Elements Mac before version 14 Mac? If so, what keying effect have you been using for your green screen projects?
Any questions or need clarification, please do not hesitate to ask.
The Videomerge effect (in the Videomerge category of effects) is designed to replace the Chroma Key or Greenscreen Key on the Mac.
video merge and difference matte are not working for me. Tried everything and no luck. any other ideas?
Not without more information on the nature of your key clip.
I'd recommend you start a new thread and we can discuss it. If you can include a screen capture of your green screen clip it would help.
