I'm trying to figure out how to chroma key but when I try to use a slightly older tutorial the video behind the green screen video becomes darker and doesn't retain the original colour so how do I fix this?
Normally by using the right green of your backgrond as colour to key out. But you did not tell which program and buildnr. you use, not what your sourcefile is (MediaInfo properties), not what kind of project you use and not what you do try to chromakey something, so further help is impossible.
You need to adjust the key mask with the sliders "Low Threshold" and "High Threshold" until the mask is clean. "Clean" means the mask consists of pure black and pure white without any gray tones. Use the "Show mask only" option while tuning the chroma key thresholds.
Check that you haven't accidentally reduced the opacity of the background video on your track below? It's easily accidentally done when dragging a clip and not easily spotted. It is normally at the top giving 100%.
I am attempting to use Chroma Keyer for the first time in Movie Studio 16 Platinum. For some reason none of the changes are showing up. I add Chroma Keyer thru Effect FX and the changes don't happen no matter what color or sliders I use. I have used Chroma Keyer before in 14 with no problem. Is this some kind of bug in 16? Is there something different in 16?
