Hi,

Is there a possibility to only make one color transparent with chroma key for use on a background?
For example... I opened a PNG-file in Paint which I want to place on a background; for example:
http://img3.wikia.nocookie.net/__cb20131215002905/nickfanon/images/c/cc/South_Park_Stan_Kyle_Cartman_Kenny.png

I made every white around the 4 characters green (0,255,0)

When I use chroma key with all the sliders, there always seem to be some transparency in the other green colors, whatever my slider-settings are... Especially the front of the cap of the second character...

Anybody knows how I can use the Chroma Key well? I also have the NewBlue FX chroma key plugin, which works better but still not as great as I want to...

Thanx in advance... Grtz, Peter

Hi,
The link to the image you posted ( I saved the image) already has no background, so when you import the image it can be overlay (inserted on a lower track) and whatever is in the track above will show through. By applying a Chroma Key and color that is that is selected as the transparent color, if contained withing the image will also be transparent. Your line up of characters can be imported as is and overlayed on a background.

Not seeing that. Use of the Tolerance of Intensity control resulted in a reasonably clean key.

Adding to comments from James, here a green background was first added to your image, then chromakeyed over video.
