I just uploaded the new tutorial that shows how to take some green screen video footage and key out the background in After Effects. From there I export the video and integrate it into Flash. Finally I turn it into an AIR application so you can see the video transparency over the desktop. If you want to use the clip shown in the tutorial you can download it here. Check it out at http://www.gotoandlearn.com.

Good tutorial, I had always tried to learn it but I did not knew how.
Hi, Lee
what i want to say…. it’s amazing !!!, thanks for all.
263 MB for the example file?!?!?!?!!?
Oh My God!
GREAT TUTORIAL
thank you very much
The Creative Cow guys have a similar tutorial in about After Effects keying too.
Thank you for this great video tutorial
Hi Lee:
Fantastic & inspiring tutorial as always. Just gives me many useful ideas for projects. Had to watch the tut on-line as am getting an Error -2048 when I download the QuickTime file. All others tuts have downloaded and played back flawlessly.
Anyway, many thanks again for sharing your knowledge and techniques. It makes learning AS3 a pleasurable experience.
Kind regards,
Chris.
Couple of questions- You used HD camera right? DV is much harder to key. What kind of camera did you use?
I was surprised you used AE to encode the flv, I always thought that one of AE’s weaknesses was encoding so I always tried to use encoding specific programs.
Hi Lee,
thanx, that’s pretty cool. I’d like to see more of this interaction between Flash and After Effects
Hi, Lee
I try to open this tutorial in Quicktime and this dont working. Quicktime “say” to me:
“Error -2048:Couldn’t open the file green.mov because it is not a file that Quicktime understands”
green.mov the tutorial , not the clip from the tutorial…
All other of your tutorials are working
what to do?
p.s – Amazing tutorials you have & i learnd a lot
great tutorial. Makes me want to upgrade to get aftereffects
Great! Thanks!
For those who have downloaded the tutorial you can change the extension to .mp4 and it will work. I am uploading a fixed version now though.
Way off topic, but still in the field of Flash…
Is there anyone who can confirm this error? I’m wondering if perhaps my installation was somehow corrupted.
import mypackage.MyClass;
var mypackage:Object = { test:’WhyConfusePackageWIthLocalVariable?’ };
trace(mypackage.test);
//1202: Access of undefined property test in package mypackage
Lee what is up ? You seem to move towards video.
Are you planning on doing a tutorial series on basic website
skills. Like Liquid GUI, XML menu with a menubutton clas, etc.
So that we can gotoandlearn how to do amazing technical websites.
I know a lot of people, like myselve who are expressive in colors and typography and get a headache of scripting.
At the moment I do all my stuff myselve, but in a really slow pace.
Would be great build a great website together with you, through a series of website based tutorials.
awesome.. lee is god
Hi Lee,

Great tutorial.
I have a question though about exporting a flv from adobe media encoder, from a mov file created in after effect. The original file is 1280×1024 but every time I export the flv, I get 2 black borders on the sides. I made sure to pick the right preset (FLV, the one that should keep the same dimension of the source file) but I can’t get rid of those borders…
Any idea?
Thanks a lot.

Nobody’s forcing you to do the tutorial
Thanks Lee – I love the After Effects tutorials when integrated with Flash. I dug up the UFC one the other night. Keep up the good work!
Chris
Other Lee-
to answer your question, when changing variables within classes you can set the variable to public, but in best standards you should use getters and setters, it allows for much more control over what is being inputed so that it doesn’t fall in an invalid range. Check out ActionScript 3.0 Design Patterns as a great resource for OOP.
Great tutorial.
Show us more after please!
First time working with Air and for some reason I can’t get the .air file to install. Get this every time “This application requires a version of Adobe AIR which is no longer supported. Please contact the application author for an updated version.” I spent like 4 hour last night surfing blogs and forums with no luck. Is any one get the same problem. I did install the patch for Flash CS3 and then installed the new AIR runtime. Also its not just with this but all .air files I’ve downloaded from here accept for the Fake Receipt file. That install just fine. Thanks guys ~ Wes
awesome great job
This is a great tut. Thanks for sharing you knowledge.
This tutorial is exactly what ive been looking for. After about 5 days of frustration and other half assed terrible tutorials your tutorial got the job done. Keep up the GREAT WORK.
