ColorKeyFrame Description

The ColorKeyFrame filter is similar and based on ColorYUV AviSynth filter. In Avisynth it is a hard to set different color correction for various part of clip, especially smoothly varying correction. (the Animate function is not very convinient). There are two functions in new plugin: ColorKeyFrame and ColorInterpolate. Several ColorKeyFrame commands can be used to define color correction data for some given frames (key frames). ColorInterpolate function make color correction by given values at key frames and smooth transition of color correction between key frames by linear interpolation of the color correction data. If you define exactly one key frame, the color correction by ColorInterpolation will be uniform for whole clip, just as ColorYUV. Plugin uses some hack of Avisynth interface to transmit its setting (the similar method is used by DGDecode, IVTC, DePan, MVTools, etc). Output of ColorKeyFrame function is special clip with color correction data (for given key frame and previous key frames) in framebuffer. This output can be used as a source for next call of ColoKeyFrame for defining of correction of some other key frame, and so on. Finally the output of last ColorKeyFrame is used as second input clip (keys) for ColorInterpolation function to interpolate the color correction.
