Keyframes are settings that are applied at specific points, these settings are responsible for modifying position, scale, rotation, opacity, etc.

Slow Motion: Slow motion reduces the speed of the video, some ways to achieve are stretching the duration of the video clip by specific amount, other ways is to capture the video at higher frame rate and then play it back at lower frame rate.

Green Screen: Also known as chroma key, is a popular technique used in video production to replace a specific color (usually green) in a video footage with another image or video. The idea is the editing software and the user agree on a color, the color will then be made transparent by the software. After that, we can use the transparent background to replace it with another footage.
