New tutorial on green screen fundamentals

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.

    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

    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

    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.

    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.

    Martin

    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!

    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.

    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
