This filter is a port of Donald Graft's KernelDeint (Avisynth). It is very efficient.
Parameters:
Field order
Threshold
Sharp
This parameter, when set, selects a kernel that provides better vertical resolution and performs some sharpening of the video. For less sharpening but also less vertical resolution, set this parameter to false.
Two way
Selects a kernel that includes both the previous and the following fields for deinterlacing, otherwise the kernel includes only the previous field. The latter one-way kernel is faster, crisper, and gives less blending (this last advantage makes the filter perform better on anime). The Two way parameter is included in case users want to achieve the behavior of previous KernelDeint versions.
