Ssis698 4k Reducing Mosaic Exclusive //top\\

This is the "magic" step. Most mosaic reduction works spatially (within one frame). SSIS698 looks forward 3 frames and backward 3 frames. If a mosaic appears only in Frame 4 due to a bitrate spike, the algorithm borrows clean data from Frame 3 and Frame 5 to "patch" the error. Because it does this in the frequency domain (not the pixel domain), the patch is mathematically seamless.
