Question

What do you understand by masking effect in Flash movies?​

Answer 1

Answer:

Masking is a way for you to control the content that your audience sees. For example, you can make a circular mask and allow your audience to only see through the circular area, so that you get a keyhole or spotlight effect. In Flash, you put a mask on one layer and the content that is masked in a layer below it.
