What is a mask
It can be understood that the mask is a piece of cloth , The following are all cloth , It's just that their materials are different 

Then cloth can have different shapes , These shapes can be cut out later


For example, there is a video playing below 
If I put a black cloth over the video, we won't see anything , And we can only see this black cloth 
If we want to see the video content, I just need , Cut off the part you want to see and you can see
This is the concept of mask , We masked the video , We can cut out the video we want to show ( It can be any shape ), Hide the parts you don't want to show , These operations are all controllable …
Be careful : Multiple masks can only have one mask for use reversal , Otherwise there will be conflict
Use mask
We use a mask to put the video 1 Video in video 2 It shows 
Mask video presentation

Use mask juice to turn sugar beans
Premiere- Mask -( Fruit juice sweetened beans )
summary
1. The mask can make the video partially visible or invisible , The most common method is to use a pen to draw a mask .
2. Mask compositing requires manual path drawing and keyframing , Adjust the key frame of the corresponding layer to achieve the desired effect ( Keyframes need to be adjusted patiently. Don't worry ).
