Black Screen Keyer

[John Fishback]

You’ll find folks on both sides of the fence with that one. Search the Cow here in FCP forum and also the Cinematography forum and you’ll find a lot of discussion.

Hello,
I am soory, I forgot to inform clearly my situation :
Usually, I work with Green Screen. But recently, I was travelling, so no green screen. I have shooted in midnight, a dark night. I lighted only my carracter, and the background is completly black.
Now i’m back and in front of my Mac Pro. I’d like to put different landscapes behind this carracter.
My question should be : How to key with that Black Screen ?
So please advise me.

I am sorry, I have any experience about Keying, I know only using Green Screen. I don’t know anything about Matte.

As was mentioned earlier, try a luma key.

Watch the tutorials I linked to earlier, that will give you an idea.

Where are you planning to pull the key? In FCP itself?

You say that as though it were a bad thing…

Another thing to try is to put your clip over a background and change the properties of the clip you want to key to “Screen” mode. This will filter out the black and leave luminance.

It’s worth trying depending on what background you want them over.

Hi Jeremy,
I have watched the first link, it is very interesting, I’ll continue to watch others.That give me a lot of knowledge. Thank you very much.
My real problem is :
I did’nt want to use black screen, but I was obliged, because I was very far from the “civilisation”, I light my carracter with wooden fire light and my portable light !!!
So I’m looking for the solution : How to use that black blackground.
Best regards

Hi Dave,
I must emphasize this :
During the shooting, I was very far from the “civilisation”, no electricity, no facilities. I must shoot in night time. I light my carracter with wooden fire light and with my portable light !!!
My only problem is : How to use that black blackground ALREADY (accidentaly) shooted.
I post to all of you in hoping to receive some solutions in that particular technical situation.
Best regards
