What to expect

The finished add-on will have the following features:

• Integration into the UV/Image Editor
• Ability to create and edit 2D Bézier masks in the UV/Image Editor
• Key frame animation 
• Soft edges 
• Generated masks available in the Node Editor

Basically, it will allow you to open a movie or image sequence in the UV/Image Editor, create one or more vector masks, animate them and use them for your composite.
