Overview BCC Flicker Fixer is a filter for eliminating flicker from source footage. It provides 3 different methods for removing flicker. The Frame Analysis method is intended for use with clips with flicker that is uniform throughout the frame, or at least uniform within a contiguous block of the frame – e.g. Flicker that is caused by unintended shutter speed or aperture variations from frame to frame.

The 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, however the Temporal options are most suitable for clips without fast moving objects. The Frame Analysis method analyzes the whole frame, and is not suitable for clips where the flicker is limited to a small part of each frame unless that part can be encompassed by a sampling mask rectangle. 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, however, use the Mask and key controls to isolate the non‐flickering part of the clip and prevent this flicker from being added. The Temporal Smoot h i n g method processes each pixel independently.

This flicker fixer 'effect'he describes might be useful (fixes flickering camera images) but I don't seem to have it although Kevin indicated it was included among the BCC effects we got with MC6. So my question is whether I need to do something to get an 'updated' free series of BCC effects for my Avid MC?

If part of the image is flickering and part is not, you can usually get good results by processing the whole clip as long as there is minimal motion in the clip. The filter will produce some softening (since it works by smoothing) in the non-­‐flickering part of the image, and you can use the Matte controls to isolate this region and minimize the image softening. We recommend rendering the filter in 16 bit or float, especially if the Temporal Smooth YCC method is used. Parameter Controls Presets and Common Controls BCC filters come with a library of factory installed presets plus the ability to create your own custom presets and preview them with the BCC FX Browser™. BCC filters also include common controls that configure global effect preferences and other host-specific effect settings. For more information about working with presets and other common controls,.

It provides several variations on basic split-screen views with the filtered clip placed next to the unedited original. For more information on the Compare Mode.

There are three options: • Frame Analysis analyzes the color range of each frame, and adjusts each pixel based on the difference between the RGB color range of the current frame and the average range of the surrounding frames. This generally works well if the flicker is uniform over the whole image. 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 Limit Sampling controls to isolate the analysis phase to just a sub-portion of the image. Furthermore, you can use the Mask and key controls to isolate non‐flickering part of the clip and prevent the average flicker correction from being added. • Temporal Smooth RGB and Temporal Smooth YCC compute a weighted average of each pixel with the same pixel at surrounding frames. The filter assess that the flicker is producing small frame-­‐to-­‐ frame changes in color, so pixels that are close in color to the pixel in the current frame get more weight than pixels that are further away in color. This causes small changes caused by flicker to be averaged out, while large changes caused by action are left alone.
