In the viewer, iMovie removes the green or blue from the green-screen clip to reveal the background clip behind your subject. If the video overlay controls aren’t shown, click the Video Overlay Settings button above the viewer, then choose Green/Blue Screen from the pop-up menu.Because the clips are connected, the two clips move together when you rearrange clips in the timeline. Trim and move the background video clip to match the length of your green-screen clip.Add the green-screen clip above the background clip in the timeline. ![]() With your project open, add the background video clip or still image to the timeline.I told you it wasn't too complicated! Have any questions? Let me know below and I'll do my best to answer them. If you do run into any shadowing problems, one trick I've learned that can work is to put a light behind the screen. This will help to bring some of the shadowing down in intensity, if it exists at all. This is a generally accepted way to light a subject when recording for green screen: iMovie happens to be pretty great implementing green screen tech, and the Mac's built in iSight is generally pretty capable, so you shouldn't have too many issues. Sometimes lighting can be tricky, but when working with lighting, remember these keys: you want the lighting even, and you want it bright. Unless you're doing this for professional reasons, you can basically use any generic lamps you've got lying around the house. Once you've recorded your clip, drag it up onto the background, and when you release the mouse button and the menu comes up, click Green Screen. Your recording will now be superimposed onto your selected background! This is much easier than you may think. While you can go all out and either buy a fabric green screen or paint a wall green, you can also create one for almost nothing out of green poster board. Just scotch tape it onto a wall, and bingo, you've got a perfect, wrinkle-free green screen. Now, capture video of yourself doing whatever it is you want right into iMovie, by clicking the camera button on the left side. Now you'll need to film yourself to add on to the background. First, you'll need a green screen. Next, open iMovie, create a new Project, and drag it into the Project section at the top left corner of the screen. To adjust the length of the background to match the movie you want on the background, click the gear in the lower left-hand corner of the clip and select Clip Adjustments, then change the time appropriately. This can be a video or a still image, depending on what the purpose of your video is. ![]() Now that you've enabled green screening, the first thing you need to do is decide on what background you want to use for your video. While they are labeled as advanced tools, they're really easy to use. This will make the cool options like green screening, picture-in-picture, and cutaways available. Before doing anything, go to iMovie -> Preferences, and place a check beside " Show Advanced Tools". ![]() When I first started using the green screen function in iMovie, I was super confused because as much as I looked, and as confident I was that I was doing everything right, I couldn't find green screen in the menu! There's a simple solution to this problem, and I'm going to save you a ton of time here by cluing you in. All new Mac's come with this though, so if you aren't sure, open your version of iMovie and go to iMovie -> About in the menu bar to see which version you're using. If you don't have the newest version of iLife, don't bother trying. Keep in mind though, the green screening feature is only available in iMovie '09.
