keylight artifacts
Hi,
i´m working on some greenscreen shots, comparing different keyers and settings.Keylight is giving me some headaches. It does a really good job on the edges and for the despilling, but it also introduces horrible artifacts within the image. I tried different settings to avoid it, but it seems, that only switching the keyer to “intermediate result” gets rid of those artifacts.
There doesn´t seem to be any information inside the image to justify such artefacts, the matte is clean it looks like there´s some problem in the despilling algorithm. One thing that improves the image is when I turn the replacement mode to “hardcolor”. Still you can see those artifacts, but it´s slightly better.
Any idea what could cause this problem? I also tried primatte, which is doing a pretty good job, but not as good as primatte would do concerning the edges.
Here a link to an image that should clarify the problem.

Thank you for any help

Hi,
i found out that there are some artifacts in the blue channel, which seemed to be created from the conversion of the files to the tif sequence i got. The problem is not in the raw files…
just to let you know
