S_FlickerMatchMatte Adds flicker to the Source clip using the flicker from a second Match clip, in the areas specified by a Matte. To use this effect, select a frame where you want the Source brightness unchanged, and hit the Set Match Level button. When other frames are processed, the Source brightness will be scaled by the average Match brightness within the Matte, relative to the Match Level. In the Sapphire Time effects submenu. Inputs: Source:  The current layer.   The clip to add flicker to. Match:  Defaults to None.   The clip to copy flicker from. Matte:  Defaults to None.   This clip specifies which Source areas to measure the flicker from. If this input is not provided, the Alpha of the Match input is used as the Matte instead. It can be inverted with the Invert Matte parameter.

Parameters:

Match Level:   Default: 0.5,  Range: 0.01 to 2.
The average Match brightness in the Matte for which the Source input is unchanged.

Set Match Level:   Push-button.
Pressing this button has a side effect of setting the Match Level parameter to the average Match clip 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. On FCP, this pushbutton could not implemented so you need to adjust the Match Level manually.

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 on, inverts the Matte input so the effect is applied to areas where the Matte is black instead of white. This has no effect unless the Matte input is provided.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

All Opaque:  Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).

Normal:  Process opacity normally.

As Premult:  Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.
