That should take care of it (and as a bonus, you can make a luma key if you set the hue tolerance to 100%) > Secondly when a wiki entry is made it would be worth suggesting the > application of a very small zoom blur on the alpha channel following > the chromakey effect. Yes, I agree. I didn't really have time to put in the blur, and since it was available as a separate plugin I didn't put it in. I should really write a document that describes how to use it anyway. > The spill control is a really effective development for this type of > work and the plug-in as a whole takes the keyed areas out agressively > and quickly. Well done and thankyou. > Thanks :-) I couldn't find any good way it could be done, so I just desaturate the colors that are close to the key color (the amount of desaturation depends on how close the colors are). It turns out it works good enough, even with a crappy footage. If you know better algorithms, I'd be happy to have another pass at it. I'll get back to coding next weekend, to add the control and make it as a clean patch we can integrate in the SVN.
