Is there any way to subdivide an already created mask. I'm working on a project where I have already manually masked about 50 frames (about 2 hours' worth of work), when i realized that there aren't enough vertices (is that the word?) in the mask. Is there any way to fix this without just making a separate mask?

    What would the drawback be of creating an additional mask? When rotoscoping complex shapes, having multiple masks for various parts is quite usual.

    For this particular structure I'm rotoscoping a person, and don't have enough verticies for the legs, so I don't really know how to make it not look super awkward to have two separate masks

You should not be afraid of making more than one mask. It is a lot easier to rotoscope using multiple masks for different sections. Work with simpler shapes, they are a lot easier to manage than a single, larger, more complex one with lots of vertices (or control points).



Having multiple masks will allow you much finer control: you can turn some on or off, vary the feathering and have detail only where you really need it.



See how many masks are used in the following video: https://www.youtube.com/watch?v=NR9w2TRWRlI





or:



enter image description here



You can combine different masks directly as layers



as done in this video https://www.youtube.com/watch?time_continue=482&v=5ZnJLLB1P4M



Or you can combine them in the compositor.



Use a color mix node to subtract, multiply or combine different masks in different ways.



Related: Separate Masks in Node Editor



Another tip is to use the tracking tools in blender and associate the trackers with point of the mask to automate the process.



See:



Is it possible to take a mask clip and 'connect' it to a specific point on a moving object?
