An optional mask to designate the rig area to remove.

Defines the area to repair:

• Box - repair the area inside a rectangular box, controlled by the Rig Region Box controls or the on-screen box.

• Src Alpha - repair the region defined by the alpha of the Src input.

• Src Inverted Alpha - repair the region defined by the inverted alpha of the Src input.

• RigMask Luminance - repair the region defined by the luminance of the Rig Mask input.

• RigMask Inverted Luminance - repair the region defined by the inverted luminance of the Rig Mask input.

• RigMask Alpha - repair the region defined by the alpha of the Rig Mask input.

• RigMask Inverted Alpha - repair the region defined by the inverted alpha of the Rig Mask input.

Select whether to search forwards, backwards, or in both directions to find missing data.

• Forward and Backward - searches before and after the current frame.

• Forward - searches frames after the current frame.

• Backward - searches frames before the current frame.

Sets the number of frames the algorithm looks forwards and backwards in the sequence to find the missing data. If you are getting red pixels, then increase this value.

If the Frame Range is set to a large number, the rendering time can be prohibitive. Frames Used in Range may speed up the repair by not using every frame to fill the foreground region, effectively skipping frames. However, this may reduce the quality of the result.

• All Frames - use every frame in the specified frame range to construct the repair.

• Half of Frames - use every other frame in the specified frame range to construct the repair.

• Quarter of Frames - use every fourth frame in the specified frame range to construct the repair.

• 10% of Frames - use every tenth frame in the specified frame range to construct the repair.

• Max 25 Frames - use no more than 25 frames from the specified frame range to construct the repair. This option can be useful if Frame Range has been set to a very large number.

To avoid perspective changes, F_RigRemoval searches for the missing data inside an area immediately around the RigRegion. Max Rig Movement defines the width of this area (in pixels). Fast movement in the Src input may require a higher value than slow movement.

Rig Region Box

The rectangular area used to define the repair when Rig Region is set to Box.

• Rig Region BL - controls the position of the bottom left corner of the rig region.

• Rig Region TR - controls the position of the top right corner of the rig region.

Advanced

Sets the filtering quality.

• Low - low quality but quick to render.

• Medium - uses a bilinear filter. This gives good results and is quicker to render than high filtering.

• High - uses a sinc filter to interpolate pixels giving a sharper repair. This gives the best results but takes longer to process.

Enable this to correct for luminance changes from information taken from other frames. This is particularly important if the lighting changes throughout the sequence.

Enable this to correct for minor perspective changes.

The repair is built up using slices of information from other frames in the sequence which are then overlapped and blended to give a more natural looking repair. This value controls how much the regions overlap. Increasing this value too much degrades image sharpness.

Sets the level of transparency of the red pixels used to show where the repair has failed.

Enable this to preserve the original alpha channel. By default, the alpha channel is set to white where the repair has failed and black everywhere else.
