Hi guys, i have a scene that i create a garbage matte around because the green screen didn't cover the whole screen and i want to use this in another program as an overlay beacause the background goes really pixelated in Chromanator and doesn't look too hot. How do i make the figures in the scene an overlay, everytime i render out the keyed image it has a big black surrounding area around the figures (keys great though smile )

So basically all i need are 2 figures walking with no background so i can place them on a background in another program...any ideas

Thanks

To my knowledge, it's not normal for a background image track behind another track to appear pixelated in Chromanator. Maybe there are some settings on your image that are causing it to render pixelated.

But to answer your question, one method would be to create a green BMP (or JPG) and place that on the track below your actors. That way the keyed area from your actors track will reveal the green BMP underneath.

So in effect you would be rendering your actors onto a perfectly coloured greenscreen. :-) Then import that into your other program and key out the green.

But again, in my experience of Chromanator, background images appear fine with no pixelation.

What are the dimensions of the image you're using as your background? & what format?

And what is the size of your project file? 720 x 480?

If it is, it's just pixelly because 350x 263 is too low resolution to have as a background for a movie that's larger than that. It's going to be pixelly whatever program you use. Try using a bigger image, preferably as big as the project settings.
