Requirement

Use of Video Editing software with chromakey or ultrakey capability.

What is a green screen?

This is a chosen color that can be used to remove the background. It was determined by people in the field that green would be the best color to use to remove the background when video editing. It works really well as long as your assets are not wearing green.
You can see an example of a green screen mistake in my Doodly Bugs and Frustration Video or in the full version of my Doodly Walkthrough but it is quick and you will miss it if you are not watching closely.

Why would I use a green screen?

Green Screen will allow you to replace a a background or object with something else. For example, you want to display the drawing arm on a different background that is not offered by Doodly, like ones that you can pick up from Production Crate:

You can see an example of this in the same Doodly Bugs and Frustrations Video tutorial

What is Chroma or Ultra Key?

These are terms used within video editing software to key out specific colors. Anything placed on a layer behind the video will show up behind the doodle drawing. Chromakey is used with almost any video editing software. Ultrakey is currently only used for Adobe Premier.

Frequently Asked Questions

A green screen is a specific background color chosen to be easily removed from a video. Professionals selected this color because it allows creators to erase the background smoothly, provided that the subjects or items in the video are not wearing or containing that same color.

Using this technique lets you swap out the original background or an item for something completely different. As an example, you could show the hand drawing animation over a custom background from another source instead of being limited to the default options provided by the software.

To successfully apply these effects, you must use an external video editing program that includes features for removing specific colors. The software must specifically have tools known as chromakey or ultrakey to process the footage properly.

These are specific functions found inside editing programs that allow you to isolate and remove a particular color from your footage. Once that color is keyed out, any images or videos you place on a lower layer will become visible behind your main animated drawing.

The most frequent error happens when the objects or characters in your project include the exact same color as the background you want to remove. If your animated assets contain that color, those parts will also disappear and reveal the layer underneath them.
