NEW: Blue Screen Effect, part 1 – Keying in AE7
This tutorial shows you how to key out a blue (or green) screen background from video and export for use in Flash 8 and higher.
Part 1 deals with After Effects, Part 2 (coming soon) will show you how to import the video into Flash and play with the alpha channel effects.

Nice work man. Tell Mister X, I’m on the way to WAL-MART now… =)
found it for less than a $1 sqare yard. Who doesn’t buy blue these days?
Hi,
I got one question.
When we key out the color is it transparent or not when we import it to flash?
Nice tutorial by the way.

Hi hamferus,
When you export the movie from AE7 as an flv with the Alpha channel encoded, then bring it into Flash, it will show the keyed out areas as transparent.
If you export as a Quicktime mov with millions of colors+, and you play the movie in the Quicktime player, the background will not appear transparent. Flash 8 takes in video and will automatically turn the alpha channel transparent. Any video editing program that supports alpha channels will also see the Quicktime video with transparency.
Hopefully that answers your question… Thanks for the compliment!

Love your tutorials..hope to see part two of the AE and some more related to that topic.
Could you maybe make a tutorial that’s topic would be about optimization footage before importing to flash..and how video or 3d rendered movies should be exported to preserve good quality and lesser file size ?
I think that would be of great help not only to me but to many guys (and girls?
) out there that are not sure if they’re getting the optimal filesize of the output swf’s for example website design, etc.
Keep it up B.
Hi-
Good tutorial by the way. I’ve never seen one that made it look so simple!!
Anyway, you said there were many places on the net to find out the exact shades of blue and green that are used to acheive the best effect, but I can’t find them anywhere. I never knew it made a difference either until you said it, so now I’m leaving it up to you to tell me where I can find these magic shades!! Can’t wait for part 2 by the way….
You’re the man
Thanks Sam.
Now that you mention it, I can\’t recall where I read which specific color of green or blue works best. It seems there are plenty of companies out there willing to sell \”film quality\” green screens, etc. (mostly they cost way too much). Supposedly there is paint out there designed for chroma-keying too.
I think the point is to use a shade of green or blue that is not found on the subject you are filming. I noticed with my own low-quality video, if I color-ranged the wrong shade of blue, parts of my eyes disappeared. (blue eyes…)
I\’ll explain a few more techniques I\’ve discovered in working with low-quality filming that can compensate for problems like losing my eyes, or blurring the rough edges of the subject in Part 2.
