Hey guys, I hoped you could help me out with GreenScreen(Chroma) effect. I wanted to use 3D model viewer of one video game to make some funny videos with it and also to experiment and learn more about Chroma keys from making some of these videos.

But the problem is that, this model viewer has.... bad background. Check yourself, link below. I tried to reduce intensity but I still get dots on the screen, and if I reduce it too much then the character starts to fade.

I hoped for some pro tips if it's possible to use Chroma effect properly with this kind of background. This site renders a pure HD models so there are no alternatives. Any advice would be useful. At least to get rid of the dots, minor quality damage is acceptable.

Hi RobiePAX -

The difficulty with that model/background is that the same colours are in the background and subject... so when you chromakey out the charcoal background, you'll also take out parts of the model (hands & shadows particularly).

When video is shot with green screen (later to be keyed out), it's important to make sure the subject colours aren't similar to the background.

Is it possible to remake the model with a contrasting (green) background? That would make your job less impossible!

Cheers - Tony

I know it's best to use a blank color that is not present in desired model(subject). The problem is that I can't change the background color of that flash software, but I really want to use it.

I hoped there are ways, maybe long ways that I don't know about, to change the background using PowerDirector after the animation is already recorded into video file.

One long way I know of is to put the image in a program like Paint.Net free graphic image editor. Or one that you might have and erase the back ground. You will be doing a lot of zooming when you get close to the subject. It can take hours. I don't know about a 3D one

I did this with a picture of my motorcycle for I could put motion to it and use it on a screen shot.

Good luck.
