Avid Matte Key
When you bring in Matte Key effects from your Avid system, they will result in Luma
Track Mattes. This is good, but what isnʼt good is that your Avid media is in the 601
color space, so your blacks will be RGB 16 and your whites RGB 235.
The composite on the left has a bit of the spaceship motor stage bleeding through the
next shot (note to the left of the “A” where the arrow is pointing), while the right side is
correct.
You will want to adjust the matte layer so that it is in the RGB color space and its blacks
are RGB 0 and the whites are RGB 255.
To do this, select your black and white matte layer, then apply the Levels filter from
Effect>Color Correction>Levels.
