- about the file
  - you can use transparent images that only contain the shapes you need
  - or border withblack (or other colors with different shapes)
- the shapes should be Featheror other antialiased borders
  - without feather you got:
    for
  - with feather you got:
    for
  - y, the v2mixer will copy the feather(antialiased) from your image. look closer:
    and
  - why doesn't it specify a number to autocomplete?
    - remember, you don't have to do the same fade(feather) for than all, you can fade 10 pixels for the top, but 50 pixels for the bottom, and the bottom will be composited with a long tail shadow(or the translucent, any size, anywhere of any intensity).
    - so we can't limit that, the art of your amazement.
- the border
  - the three corners of the picture with the same color will be used as the background, the others will be used as the foreground(the mask)
- the size
  - you may create an image same size as your video, then both X,Y as 0, this is the easiest way.
- on top of that, you can draw arbitrary images yourself, instead of very symmetrical geometry, which might look better.
