Canvas colour Request

I do a lot of green/blue screen work and currently have Effects lab pro. It would be helpfull if the canvas could be rendered in green or blue if the quad is less than 100% so the remaining area could be used as green or blue screen.(Its currently rendered as black which possibly could be chroma keyed with composite lab - which I don't have yet) I haven't tried this in Composite lab trial version but this feature would still be useful in Effects lab.

You can change the canvas colour by clicking on the black box with a white border in the menu (below the menu bar)
From here you can then choose what ever colour you want.
Is that what you meant?

I tried that initially but the concept is so one can see where the canvas is and any colour can be used but it will not render the canvas in the colour chosen. Chroma keying black canvas - I don't think will be successful.

A chromakey might not be either successful though (if you have any blue, green or whatever in the image).
EffectsLab supports alpha channels though, so just retain the alpha channel when rendering and then key that out. You don't actually have to do anything this way, it's all 'built in' so to speak.

Yeah, just render out with an alpha channel. There's no point using enforced greenscreen/bluescreen stuff when dealing with computer generated images - just go straight to the source and retain the alpha (transparency) information.
Greenscreen/bluescreen is a technique that is only really needed when you're filming with live action cameras.
Unless I've misunderstood your first post, that is...

Thanks for the info - thats helpful. I haven't really done much using alpha channels so I am probably missing out on some stuff. I'll read up on alpha channels and start experimenting. Thanks guys.
