Removes temporal color changes from the Source clip using a Matte clip to specify the area where the average color should remain constant. To use this effect, select a Source frame that has the desired color within the Matte, and hit the Set Hold Color button. When other frames are processed, their color will be scaled so the average color within the Matte is equal to the Hold Color.

In the Sapphire Time effects submenu.


Source:  The current layer.   The clip to remove color changes 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 Source input is used as the Matte instead. It can be inverted with the Invert Matte parameter.


Hold Color:   Default rgb: [0.5 0.5 0.5].
The requested average output color for the area within the Matte.

Set Hold Color:   Push-button.
Pressing this button has a side effect of setting the Hold Color parameter to the average Source color 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 Hold Color 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.
