Additional Green-screen Information

Though it’s easier to use than the Pro version, Final Cut Express is overkill for most of our harebrained video ideas. You can add basic two-layer compositing and matting effects to iLife ’06’s iMovie HD (but probably not iMovie ’08) with GeeThree’s Slick Effects Vol 4 ($49.95, Once you install the Slick Effects pack, you’ll see the new goodies in iMovie’s Effects library (under Editing > Video FX > GeeThree - Slick 4).


1. Preparation Station

Slick works around iMovie HD’s one-video-track limitation thusly: You add a clip to iMovie’s Timeline, and when you apply the Slick filter, its configurator prompts you to select a clip from the Finder to use for the overlay - so it’s best to trim your overlay clip for length before you apply the filter. Load the clip into QuickTime Pro or iMovie, trim it, and resave in its native video format. Or, a better one - just don’t add any compression yet, as that’ll decrease the clip’s quality. You can scale and reposition the overlay in the Slick filter dialog, so don’t worry about that yet, but feel free to manipulate the clip with iMovie’s color filters, or rotate and/or flip the orientation in QuickTime Pro, where the Movie Properties window (Window > Movie Properties, or Command-J) provides handy Flip/Rotate buttons.


D’oh! You posed for the wrong side of the brisket - no worries, you can flip the clip in QT Pro.

2. Bring in the Background

Drag the background clip into iMovie’s Clips browser, and then into iMovie’s Timeline. Click the Editing button, then the Effects button, then scroll down to the GeeThree - Slick 4 folder and press the VidMix icon. Click the Configure button to summon the dialog box with VidMix’s controls and overlay-clip picker.

Hey Niko,

Could you possible make your project files available for FTP? I'm trying to learn Final Cut Express and would like to run through your demo, but don't have ant footage or a green screen currently. Thanks!
