Protect an object from Ultra Key?

[Pampurrs]

I have a submect that has a graphic of a rose with a green stem on it.  When I shoot it with the green screen and apply Ultra Key, the stem washes out.  Is there a way to protect that graphic from Ultra Key?  Or do I need to  use a blue screen instead?

Thanks!

Use a mask over the stem.

A yes next time use a blue screen on a green stem.

Thank you for the reply...

"Use a mask over the stem."

Sorry, but I'm new to Premier Pro,  can you explain  how I would do that, or point me to a tutorial that explains it?  I know how to create a mask, but how do I use it to prevent the stem from getting washed out by Ultra Key?

Cheers!

Cope/paste clip without the key and superimposed in V2.

Draw mask from opacity over the stem.

Thank you, I'll give that a try

That method worked brilliantly.  Thank you very much!
