Combining Green Screen Effects with Rotoscoping
Green Screen effects are employed for a wide range of uses in animation, special effects, and film and studio production. The technique is also applicable to digital rotoscoping as well. Rotoscoping is an animation technique that involves drawing onto a glass panel that has some film projected onto it. With regards to modern methods, the equipment has been replaced by computers and green screens.
Step 1: Setting Up
You will need to setup a green screen behind your subject, and use the desired camera and footage parameters to shoot a video clip. Once this is done, you will import the video footage to video editing software and extract singular frames out of the video footage.
Step 2: Implementing Rotoscoping
You will import the required frames from the footage to photo editing software or a vector based illustration tool, such as Adobe Photoshop or Adobe Illustrator. Create a new layer on top of the original frame and then start by marking out the dominant shapes and lines on the frame. You will now fill up the shapes with matching solid colors and then save the frame when finished.
You will now repeat the process of drawing shapes over selected frames depending on the length of the animation that you would like to create. This could be up to a few hundred frames. Substitute the green screen in each frame by a moving or stationary background of your choice in all frames, and you are now ready to render the animation footage.
Step 3: Creating Animation
You will now import the key frames into any animation software package and create the end result animation.
