Well lets see here... Composting is basically what the word says, its where you combine various footage to make one. Chrome Key is basically "blue screen" its where you have something filmed against a solid color (usually blue, green, black and white) they you "key" out the color you would like to remove. And masking is where you use a "mask" to hide a piece of footage or achieve a different effect. Well that might no be all accurate, but it gives you an idea. ------------------

Compositing: The process of merging two or more clips into one. This is the name for the whole process, not a specific technique or tool.Chroma-keying: Compositing by using a certain color in one clip as the transparent portion of the clip. Technically, could be any color, but is usually blue or green because skin usually doesn't contain those shades. Usually used to put a person or object in front of a different background when there isn't alot of interaction required with the background. Masking: Compositing by using a black and white image to define transparency of a clip. The black area becomes transparent and the white are remains visible. This allows more flexibility than chromakeying, since the mask can have a complex shape, allowing objects to pass in front of and behind others, and can be changed over time. |

Masking is a bit two-folded. masking can also mean kinda moving mattes. you draw the outline as a vector-line and are able to keyframe all of the outline points,. | |
