I've been experimenting with iMovie and the Green Screen iPad app to create our school newscasts. I know a bit about iMovie but hadn't used Green Screen before, although I've used other video editors in the past. The beauty of these programs is that students are now able to create professional-looking videos that in the past would have been done by professionals with a big budget and expensive technology.
GREEN SCREEN (DO INK) RAW CAPTURE First, I captured the video of the newscaster in front of the green screen using an iPad in video mode. I made sure the entire background was green, of course. I could've also used iMovie or Green Screen as well. COMPOSITING The bottom timeline is the background layer, which is the usually the backdrop image we want to use. Leave some space for your actor. The middle timeline is where the video (actor) goes. The chroma key filter is already turned on, although it can be switched on or off. The chroma colour circle and sensitivity and audio can be finely adjusted. The top timeline is used for another upper top layer above both layers, which can be used for graphics or animations. Interesting note: any image or video can be two-finger touched to be adjusted in size or position. PHOTOS/IMAGES When you insert a photo background onto the bottom layer, it goes on forever. So, in order to stop it, you need to line up you red marker at where you want the video to end, and then press the small clock, which effectively dims the rest of the timelines and end the video. INSERT/REMOVE GRAPHICS OR ANIMATIONS To insert a graphic/animation, use the top timeline and press +. To resize it, you can do the two-finger touch to increase, decrease or simply move it to another location. To end it, you will need to line up the red line to where you want it to stop, then insert another graphic and with the chroma filter on, adjust the sensitivity to the top, so the entire image disappears. BACKGROUND CHANGE If you want to change the background, place the red marker at the spot where you want a new background, press + in the bottom timeline and add a new image/video for your background.
