Question

Green spill problem - filming in a studio

I understand that green spill means there is too much light or that the presenter is too near the green sheet. I have tried many settings - distance (as much as 12 feet between green sheet and subject) and various light settings and I am still unable to get rid of the green spill.

The quality of the recording is good but after editing, the green spill persists. I think it is more apparent for us Deaf presenters as we use sign language, ie, quick movements of hands and arms. Normally people would not spot it but we Deaf peope use our eyes and we focus on signing hands and when one looks carefully one can see the faint tinge of green spill around the fingers and thumbs.

Today I did an experiment using my ten year old hand held HD camcorder. Obviously the quality is not as good as Canon XA25 but I was very surprised to see, after editing, no green spill at all! I’m now wondering if I’m using incorrect settings on Canon XA25? The highest setting I use is 35 Mbps (50p).

However, that is not all. I decided to ask my friend to help. I sent him the original footage. As he used Apple computer and iMovie, I was very surprised to see that there was NO GREEN SPILL in the file he sent me! So what is going on? Is Adobe Premiere Elements 2020 really restricted in keying (Green chroma key)? I use Windows 10.

Advice?

You don't say if you're using Chroma Key, Green Screen Key or Videomerge to create the effect, but different tools work better than others in various situations. Can you post a screen capture of your video with the green background so we can see how what it looks like? 

 

I've got a tutorial that shows you how to do key effects in Premiere Elements. It may be a good place to start.

Thank you for your reply. 

I've tried all three - Chroma key, Green screen key, VideoMerge - Green screen key worked best but as you can see the image still shows green spill around the hands.

It could be compression artificacts or a resolution issue. Or it could be a mismatch between your project settings and video specs.

 

Open your original green screen video in the free download MediaInfo. In MediaInfo, set View to Text and then copy the text and paste it to this forum. These detailed specs will help us troubleshoot your issue.
