Hi
I have plenty of lighting but still not getting my picture as clean as I would like. I had to move into my office because of lighting and it is a bit small. I have 2 Tolifo 176S Led lights and 2 softboxes but find it difficult to improve. Any tips on lighting to improve the results? I have assumed it is the lighting.

I had the same problem. First of all: Try to lighten your green screen as evenly as possible. Then have a look at the effects room, NewBlue Video Essentials VI. They are all test versions, but try out "NewBlue Chroma Key Pro". It brought much better results as the builtin chroma keyer. You would find it better to get a small program: jcpicker, because the effect does not have acolor picker. The little program is a good workaround. I bought the effect package fpr 49 dollars.

Thank you. Will look at them.

There are many tips and tutorials for green/blue screen techniques to be found on Youtube, I advise you to watch a few if you have not.

  • Bright even lighting

  • Light source with a high CRI

  • No wrinkles in your screen. None!

  • Try different camera settings, 60i vs 30P vs 60P, etc.

  • Is your screen a quality color? I returned my first screen as the green was too "piney" rather than vivid florescent green.


You may even be affected by the fact that consumer cameras record in highly compressed formats and throw out much of the color information that pro cameras save.

Thank you. I got the green screen from a camera shop. I will iron it again to make sure any minor creases disappear. I'll try everything else too. Even light seems to be the main problem and I'll try the different options you suggested. I am using the webcam Logitech C920 HD Pro.

Go pickup the APP "Green Screener" This is what I use on my cell phone. I point it at the green screen and it shows me where I lack light and need to add more light. Best app I ever bought for doing my green screens PowerDirector Tutorials Team

Just remember that your SUBJECT needs to be brightly lit - lighting the green screen too brightly will create a green "halo" of reflection around your subject that you will not be able to get rid of and the background will eat into your subject's border. I actually light my green screen cooler so that no green refelction bounces off of my subject. Note that Hollywood does not use brightly lit green - they cool it down for the same reasons. This is how they are able to get realistic results.

Also good information, though I submit that a lighting team and $30,000 cameras may have some affect on the outcome. My best green screen attempt.

Looks great, but the "green halo" around your subject can be avoided by shooting with a cooler green screen. Super bright green is what causes that. I have softboxes that I light my screen with at about half power and I get better results. When I crank them up to full, I get green halos around my subjects that I can't clean up.

I did that in my living room, a small space, and just no room for really getting set up properly. Green screen is finicky, but can be a lot of fun. Practice practice practice.
NOTE: The Audio/video is slightly off due to the need (for the Cyberlink contest) to use the in-suite uploader and for me it never produced in-synce A/V.
