Question / Help Chromakey issue: Filtering green and pure white?

Crypt · Jan 23, 2014

Hi guys,

First post, love OBS, fantastic software.

Issue is I use a greenscreen and with the settings I have it removes green but also pure white, which can happen to my skin sometimes if I lean too close to my light source.

Here are some pictures to illustrate the problem and my log.

Code:

Before chromakey enabled

After

Can anyone help me understand what's happening here?

dodgepong · Jan 24, 2014

Can you post a screenshot of your Chroma Key settings?

Lain · Jan 24, 2014

It may be the color of your background combined with the webcam's general tint. Potentially bad color combo. The background looks like it's not very well lit either, and doesn't seem like it really stands out, which it needs to do. They need to be pronounced colors which are well lit and stand out against the rest of the coloring in the video.

Crypt · Jan 24, 2014

Thanks for the replies guys.

Here's the chromakey settings:

Jim, I agree with you that the lighting is not perfect, but there is something else going on here. Pure white is not as close to the colour chosen as some of the other colours in the picture, and they are not made transparent.

Lain · Jan 24, 2014

Chroma key functions differently than you think -- just because a color doesn't seem close doesn't mean that it can't happen. Let me explain further: chroma key operates in a different space of color, it does not factor in the brightness of a color, if that makes sense. If you set it to green and something is very white but has a green tint as well, it can also get picked up by it. Chroma key operates well with green screens by filtering out a color, specifically excluding the brightness or darkness factor of that particular color so that it picks up more area and prevents it from having potential issues with lighting.

Best results will always come with better lighting and a more pronounced color, such as brighter green or red or blue. A color that is "off" and unused by the rest of the scene is ideal. It doesn't really feel like that's the case in this. Everything feels like it has a pre-existing tint already due to the webcam.

Jim thank you for the comprehensive explanation. I had a feeling that this would be the case and there was an aspect of the chroma key functionality that I was not understanding.

After playing with the "white balance" in the actual camera properties from the camera driver I was able to minimalist this effect, I suppose white balance is a kind of tint.

In the long run I will look to upgrade my camera, lighting and green screen surface. I might move from cloth to a large roll of bright thick paper!

Thanks again.
