S_FlickerRemoveMatte Removes temporal flickering from the Source clip using a Matte clip to specify the area where the average brightness should remain constant. To use this effect, select a Source frame that has the desired brightness within the Matte, and hit the Set Hold Level button. When other frames are processed, their brightness will be scaled so the average brightness within the Matte is equal to the Hold Level. You can keyframe different Hold Level values over time to account for desirable brightness changes. In the Sapphire Time effects submenu. Inputs: Source:  The clip to remove flicker from. Matte:  Optional.   This clip specifies which Source areas to measure the flicker from. If this input is not provided, the Alpha of the Source input is used as the Matte instead. It can be inverted with the Invert Matte parameter.

Parameters:

Hold Level:   Default: 0.5,  Range: 0.01 to 2.
The requested average output brightness for the area within the Matte.

Set Hold Level:   Push-button.
Pressing this button has a side effect of setting the Hold Level parameter to the average Source brightness within the Matte at the current frame. It causes the output to equal the Source at this frame. This button retains no value itself, and is turned back off immediately after being pushed.

Matte Use:   Popup menu,  Default: Alpha.
Determines how the Matte input channels are used to make a monochrome matte.

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

Invert Matte:   Check-box,  Default: off.
If enabled, the black and white of the matte are inverted before use.
