TUTORIAL 1: Masks, Shapes and Rotoscoping


  1. Masks: How we isolate specific areas of an image, used to select an area to keep inside or outside of area
  2. “Cutting out” shape and colour correcting it
  3. Editing a frame-inserting an image where there wasn’t one
  4. Pen tool: Corner point and busier (?) point, vertex/verticies
  5. Mask Feather tool: Allows you to click anywhere in the shape and drag out a feather. Some areas can be more feathered than others.
  6. 4main sections for every mask created:  Mask Path, Mask Feather, Mask Opacity, Mask Expansion
  7. Auto trace- will take an existing image and mask it. Never perfect BUT can save a lot of time.
  8. Mattes: Pass transparency information to the layer directly underneath it. 
  9. Luma matte, alpha mattes
  10. Adding shapes
  11. Shape layers allow you to add a lot of content and edit and animate it a lot
  12. Rotoscoping: The animation of masks over time, to isolate a moving object i a scene to allow us to further work with that isolated area.
  13. Turn mask to none- still visible outlines but also visible background image.
  14. Rotoscoping a.k.a. a lot of work…
  15. Adds an effect: Roto brush (propagation & matte settings changeable)
  16. Propagation: Actual intelligent process, tries to guess where the shape is or should be. Helps with fine tuning
