Sapphire Plug-ins for Autodesk: FlickerRemove


In the S_FlickerRemove Plugin.

Removes temporal flickering from the Source clip. For example, old footage with uneven exposure times can be smoothed out with this effect. To use this effect, first position the rectangle over an area where the average brightness should remain constant. A middle or light gray area is best for this. Then select a Source frame that has the desired brightness within the rectangle, and hit the Set Hold Level button. When other frames are processed, their brightness will be scaled so the average brightness within the rectangle is equal to the Hold Level. You can keyframe different Hold Level values over time to account for desirable brightness changes.


Source: The clip to remove flicker from.


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

Rect Center: X & Y,  Integer,   Default: [0 0], Range: any, Shared .
The center of the rectangle which is used to measure the flicker, in screen coordinates. This parameter can be adjusted using the Rect Widget.

Rect Size: X & Y,  Integer,   Default: [1.67 1.23], Range: any, Shared .
The size in pixels of the rectangle used to measure the flicker. This parameter can be adjusted using the Rect Widget.

Set Hold Level: Push-button .
Pressing this button sets the Hold Level parameter to the average Source brightness in the rectangle at the current frame. It causes the output to equal the Source at this frame. (This will not work properly when in 'Redraw:Never' mode.)

Hold Level: Default: 0.5, Range: 0.01 or greater.
The requested average output brightness for the area within the rectangle.

Measured Flicker: Default: 0, Range: 0 or greater.
When processing, this parameter is automatically adjusted to record the amount of flicker at each frame. You can copy the keyframes to a parameter in other effect in order to match the flicker in a different clip, or adjust the brightness on certain frames. Changing this parameter manually has no effect.


Center Shift: X & Y,  Integer,   Default: [0 0], Range: any, Shared .
These values are added to the Rect Center, and are meant to help when using data from the Tracker.

Negate Shift: Check-box,  Default: off, Shared .
If enabled, the Center Shift is subtracted from the Center instead of added.
