Green Screen Settings
If someone has a few minutes to spare and some expertise in green screen, I would appreciate your help with a video.
This video is our typical setup for some training videos. We have made many, and so far, the chroma key and the overall look have been acceptable, but my hope is to make them better.
The space we use for recording is simply a spare room in the office, not a large studio, lights are rather close, no room to stretch out.
My setup consists of a reflecmedia LightRing on the camera and their Chromatte fabric screen. In this video, I start with a low intensity light setting and increase it to the highest setting, pausing at each setting in order to have time to determine the best light intensity setting for the chroma key effect.
I am using Vegas Pro 12 and BCC8, and therefore have access to the Boris effects such as Matte Choker, Cleanup, Light Wrap, Smooth Tone, etc., and of course, the BCC Chroma Key.
I am optimistic that someone experienced with chroma key can determine specific effects and settings to provide a quality video, particularly which light intensity setting provides the best key.
The link below provides the video and a typical background. FYI, the background was purchased from Big Stock, so be aware there are copyright issues should you with to use that background in another creation.
If you have a suggestion, I am happy to reply here, or email me directly at ba***@*****aq.com.

I looked at the video you shared, but I am not an expert with this by no means. I can share a few things I noticed, but I am interested in what others recommend to you too.
I don’t think the light intensity really makes a difference, the problems you are having are the shadows produced directly behind you, that produces that slight outline around your body and fingers. The fact that the green screen is wrinkled produces additional shadows that BCC can deal with, but avoiding them altogether will make the editing go much faster.
Normally they have the subject further away from the screen to help with those shadows, but that is not a luxury you have, so you may need more lights on just the screen to try to eliminate the shadows produced by the lights illuminating you subject.
I have heard that the BCC chroma key works better than the Sony one for trying to correct these issues and I have the same software. I just have not gotten as far as your setup yet. I tried with a cloth and a couple work lights just to try out the technique last year.

Thanks Mark, I have recieved a few suggestions about increasing distance from the screen, which helped in testing, but won’t work because of limitations in the room, I am too close to the camera.
Nevertheless, I think BCC is going to work well.
