Black Point / matte_blackpoint | Float | 0 | Sets the black point (typically the darkest pixel). Any pixels of this value are set to 0. In other words, this color is turned into pure black |
White Point / matte_whitepoint | Float | 1 | Sets the white point (typically the lightest pixel). Any pixels of this value are set to 1. In other words, this color is turned into pure white. |
Lift / matte_lift | Float | 0 | Any pixels that are black are set to this color. This allows you to, for example, match the tonal range of one clip with that of another. |
Gain / matte_gain | Float | 1 | Any pixels that are white are set to this color. This allows you to, for example, match the tonal range of one clip with that of another. |
Multiply / matte_multiply | Float | 1 | Multiplies the result by this factor. This has the effect of lightening the result while preserving the black point. |
Offset / matte_offset | Float | 0 | Offsetting adds a fixed value to the result, which, in effect lightens the whole image. You can also add a negative value to the result, in which case the whole image gets darker. |
