Flicker Fixer

The BCC Flicker Fixer filter  is designed to eliminate flicker from source footage. It provides 3 different methods for removing flicker.

  • Frame *Analysis* is intended for use with clips with flicker that is uniform throughout the frame – e.g. flicker that is caused by unintended shutter speed or aperture variations from frame to frame.

  • Two Temporal Smoothing methods  are intended for use with clips in which the flicker varies from pixel to pixel within the frame – e.g. a scene that is lit partly by natural light and partly by a flickering artificial light.

The Frame *Analysis* method always analyzes the whole frame, and is not suitable for clips where the flicker is limited to a small part of each frame. If most of the frame is flickering and a small part is not, the Frame Analysis method will generally remove most (but not all) of the flicker, but is likely to add flicker to the non‐flickering part of the clip. You can use the Mask and key controls to isolate the non‐flickering part of the clip and prevent this flicker from being added.

The Temporal Smoothing  method processes each pixel independently. If part of the image is flickering and part is not, you can usually get good results by processing the whole clip. The filter will produce some softening (since it works by smoothing) in the non-­‐flickering part of the image, and you cause the Matte controls to isolate this region and prevent any image softening.
