S_FlickerMatch Adds flicker to the Source clip using the flicker from a second Match clip. For example, a clip can be brightened in synchrony with a flashing light in another clip. To use this effect, first position the corners of the rectangle over an area of the Match clip which has brightness changes you want to copy. A middle or light gray area is best for this. Then 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 rectangle, 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.

Parameters:

Rect Corner1:   X & Y,   Default: [150 100],  Range: any.
The upper left corner of the rectangle which is used to measure the flicker, in screen coordinates.

Rect Corner2:   X & Y,   Default: [570 386],  Range: any.
The lower right corner of the rectangle which is used to measure the flicker, in screen coordinates.

Match Level:   Default: 0.5,  Range: 0.01 to 2.
The average Match brightness in the rectangle 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 in the rectangle 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.

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.

Show Rect: Check-box, Default: off.
Turns on or off the screen user interface widget for adjusting the Rect Corner corner parameters.This parameter only appears on AE and Premiere, where on-screen widgets are supported.
