So can you use green screen in 

Premiere Elements 2024?

could any recommend me a book describing in easy steps how to use the Green Screen Key  in Premiere Elements?
I use Premiere Elements 2024 on a  Windows desktop computer

I figured out with Premiere Elements 2019 that to create the effect, among the Key options (of which Green Screen isn't one), choose instead Ultra Key, which allows creation of a customizable screen of any color, using the color selector to match whatever green (or other uniform color) is in the target video. A little more work, but ultimately even more flexible, since any uniformly colored background can be used. 

Hi @mcdon47,

Update is now available and the bug related to Green Screen Key is fixed now.

Thanks,

Thank you for your comments. I did use chroma key but it never worked. I've taken a snapshot of the original video clip and another with chroma key. I have used videomerge which worked well if I used an image/photo for a background but for a plain coloured background ie blue with logo etc videomerge is not ideal. The presenter is using sign language and light is relected onto the background which is an unwelcome distraction. That is why I wanted to use green screen key which has worked well. Chroma key doesn't work at all! Thanks. 

Use the chroma key instead which is basicly the same.
