Adding your background image to your green screen video.
Once your green or blue screen video clip is filmed, you’re ready to use a video editing programme or green screen software to remove the coloured background and add in your new scene. Follow these tips to ensure a smooth edit in Adobe Premiere Pro.
Lock in your content before keying out the footage.
Before you spend time editing out your green screen background or even doing colour correction on your footage, complete a rough edit. You don’t want to spend time doing these complex tasks on frames that won’t make the final cut.
Use the Ultra Key tool.
Once your footage is narrowed down, use the Ultra Key tool in Adobe Premiere Pro to key out the background. Open the Effects panel and then the Ultra Key tab. Use the Eyedropper tool to choose your key colour, selecting an area on the green or blue screen. If you’re lucky, this will do most of the work for you. Otherwise, adjust the sliders labelled Matte Generation, Matte Clean-up, Spill Suppression and Colour Correction. These will tweak the way in which your key is being removed.
Consider edits to your new background.
Make any necessary adjustments to the new background you are adding to your video. If you’re shooting a close-up interview, add some depth of field by making the background slightly soft. “Think, ‘what would that background look like if it were really there when I shot it? How am I going to adjust for that?’” says Holtz.
Take it further with creative green screens.
Look for small, fold-out background panels that resemble a round section of green screen. You can use these to shoot keyable footage on the go. Hold the pop-up screen behind the person or object you want to shoot. In your video editor, cut a simple matte (called a rubbish matte) between the person and the edge of the green area and remove the background beyond the line of the matte.
Anything solid in color can potentially be a screen for a keying project. Creative studio Abby Priest experimented to discover whether or not they could use liquid paint as a green screen. Watch how they did it and see the stunning result of their work.
Keep your eye on the latest tutorials and updates to Premiere Pro through resources like Adobe Live and try out new ways to use Chroma Key tools in your videos. “Because editing capabilities change every few months,” explains Apley, “it’s important to be continuously learning.” As long as your lighting is set up correctly, there are countless ways to introduce fascinating new backgrounds to your projects within the world of chroma keying.
