Question / Help Green Screen keeps fading in and out

[Jordan_DWB]

Here's a sample video I just recorded of the issue:

I did a 3 hour Twitch live stream yesterday and I believe this issue only appeared a few times at most. I've included my chroma key filter settings as well. I'm confused as to what is causing this issue since it only happens at random times. There are no apparent reasons to me why it will fade in and out. The green screen is stationary and I do have lighting on both myself and the screen.

The only setting that has ever had any impact for me is the Similarity slider. I see you got smoothness and key color spill reduction values set ... I never had a need to use those.

Its sometimes good to shine the lights on the muslin backdrop by positioning the lights in back of you, pointing at the muslin.
This, instead of positioning it directly in front of you and towards the muslin.

Don't rule out your webcamera. It maybe that you have overhead fluorescent lights and they are flickering on/off. Look for an anti-flickering option.
