I eventually want to move into doing green screen videos and such so I am playing around with CompositeLab.

But for now, I just want to do green screen pictures. I was just wondering if I can do those also thru CompositeLab?

Thanx

Yes you can. But if you are going to be doing very many of them, you may want to look at Photokey, which is specifically designed for that and has a more efficient workflow for still image greenscreening. But if, as you said, you indend to eventually do video as well, then CompositeLab may be the most logical choice.

Thanx biggrin

That's what I was hoping for. I really didn't want to put out any $$$ for a new program that might not be used much after a few weeks or months.

Is there any good tuts on how to use Composite Lab for still pictures?

Thanx again.

Its essentially identical to working with video; there's not much that you do different if working with stills.

Import the still, key it, add a background.

The only part that's different that I can think of is the rendering. You will either need to set the in and out point on the same frame, to render an image sequence of only one image, or you could set up a different pic on each frame, if you wanted to do a bunch at once. Also, remember to always set up your projects Progressive if working with stills.

I have played around with the ChromaKey aspect and think I have a handle on that.

But how do I make the Key transparent and how do I load in a background image?

Thanx

Some keys default to transparency and others don't, depending on the specific key you use. I find the Auto Difference key works quite well if your greenscreen setup is decent.

You add a background by importing it, then adding it to the timeline, just as you did with the greenscreen photo. Once its on the timeline, make sure its below the greenscreen.
