Sapphire Plug-ins for Open Fx: NearestColor

S_NearestColor Collects pixel colors from the input clip's frames that are closest to the given Match Color. This can create, for example, a background-only image from a clip with objects moving over a blue or green-screen background. It can also be used to accumulate the color of a moving object over a non-colored background. The collected colors are reinitialized whenever any non-consecutive frame is processed, either the first frame, reprocessing a given frame, or jumping to another frame. You must process multiple frames of a clip in a row to observe the effect, and clearing your image cache before rendering may sometimes be necessary. In the Sapphire Time effects submenu. Inputs: Source:  The clip to be processed.
