  <p>Some however were not and done at a much lower res.  The result is naturally masks with visible pixel notches in them as you can see below.</p>

  I'm working on an experimental video that uses a mask of a person. Some of the masks were made in After Effects using the roto brush tool at full resolution, as is recommended.
  
  Some however were not and done at a much lower res. The result is naturally masks with visible pixel notches in them as you can see below.
