Masking animation fill in the gap between what to choose

Masking animation to fill in the gap between what to choose, to create a mask animation should pay attention to the matters and skills

First, a brief understanding of the principle of masking animation: assuming that there are A, B, two pieces of white paper, we drew a picture on the A, and now will be the B masked in the A, at this time, we can only see the B, but can not see the content of the picture on the A. This is the general principle of masking animation, in which B is called a hole through the hole to see the content of the A paper.

If we put a hole in paper B, we can see the content of paper A through the hole, which is the general principle of masking animation, in which B is called the "masking layer", A is the "masked layer".

For the uninitiated, here are a few things to keep in mind when creating a mask animation.

1, can not set more than one mask layer for the same layer/video

For the same video, the mask layer can only be set one, that is, there can only be one sheet of paper B. If there are more than one mask layer, it will only show what the first layer/video shows.

For example, if the original paper B is the mask layer, and now we add paper C on top of paper B, then we can only see the content on paper B through the holes snapped out by paper C, and most of the content on paper A is not visible.

For the same video, we can design a few more mask shapes, which simply means we can snap a few more holes in paper B, so that the video created is not bad.
