Filters with multiple input clipsΒΆ
There are some functions which combine two or more clips in different ways. How the video content is calculated is described for each function, but here is a summary which properties the result clip will have.
The input clips must always have the same color format and - with the exception of Layer and Overlay - the same dimensions.

1 (the last frame of the shorter clip is repeated until the end of the clip)
2 (the last frame of the shorter clip is repeated until the end of the clip)
As you can see the functions are not completely symmetric but take some attributes from the FIRST clip.
