Keying
I’ve bought a green screen and I gave it a shot. When it come to keying in AE it doesn’t go well. IT leaves some black thing moveing around in my footage. What is the caus of this and what can I do to fix this? My green screen has a darker color than other screens that iv’e seen. Can this be the problem? thx for your help.

Hi,
To start with, have you lit your greenscreen and subject so that there is a consistent colour and less green spill on the subject? If not search google for “greenscreen lighting” or similar. Also, what are you filming with? If you are filming with DV or HDV it will be a lot harder to get a good key but it is still possible.
check out https://www.videocopilot.net/tutorials.html?id=50 for help with keying, also try this if you have DV/HDV footage, make a new adjustment layer and put it above your footage and apply a gaussian blur of 4 to it. then set the transfer mode to color. this will smooth out the colour transition so that you will hopefully get a cleaner key. you may also need to scale your footage up to 101% after applying the blur as it also blurs out the edge of the frame.
hope ive helped,

Also, Andrew Kramer’s most recent tutorial, “Advanced Car Hit” has some helpful keying tips about 3 minutes in. Here is the link:

its all about the lighting, lol no. You can key good even with bad lighting if you have good software. Primatte Keyer will key a green carpet, remove noise, and get your grandma into a flying spaceship. THAT’s how good it is. ae’s keyer is trash.
