How to Chroma Key (Green Screen) Blender (free software)
Don't forget to save this project!
You can use it as a template for other videos when done.
Put yourself into your blender creations or other videos / photos. No blue screen or green screen needed! Any solid-colored wall, paper, sheet or blanket will work fine, as long as it contrasts with skin and clothing. It should be a matte finish, not shiny, for best results. You can do alpha masking two videos, transparent overlays, node compositing, or matte keying, whatever you want to call changing the background of your video or making parts of a video transparent, using all free software (blender 3D and Linux). Now with annotations.
Blender is cross-platform, too, so you can try it out on Windows.
ATTTENTION Fedora users: The blender rpm (installed via yum) MAY NOT WORK for video editing. You will probably have to download blender with ffmpeg compiled in from http://blender.org
Notice the grainy camera image? That's CCD starvation from not enough light. Lighting is very important to minimize shadows on your backdrop. It's too dark in here and I should also get a scrap of green fabric to pose in front of before doing this again, plus this camera is shit quality and I look like crap after studying for finals, but you get the idea. I will use this technique at some point, when I get better equipment. I made this video as a reminder.
This tutorial uses the Color Difference Method. If you are using a real green screen, the Chroma Key Node Method may be easier to set up (though color difference still seems to work better for me). See:
