Sapphire Plug-ins for After Effects: FlickerRemoveColor


Removes temporal color changes from the Source clip. Similar to FlickerRemove but the process is applied to each color channel. To use this effect, first position the corners of the rectangle over an area where the average color should remain constant. A middle or light gray area is best for this. Then select a Source frame that has the desired color within the rectangle, and hit the Set Hold Color button. When other frames are processed, their colors will be scaled so the average color within the rectangle is equal to the Hold Color.

In the Sapphire Time effects submenu.


Source: The current layer. The clip to remove color changes from.


Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .

Rect Corner1: X & Y,   Default: [-0.583 -0.441], Range: any.
The upper left corner of the rectangle which is used to measure the flicker, in screen coordinates.

Rect Corner2: X & Y,   Default: [0.583 0.441], Range: any.
The lower right corner of the rectangle which is used to measure the flicker, in screen coordinates.

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

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

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: on.
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.
