Removegrain
From Avisynth wiki
RemoveGrain is a simple and extremely fast spatial denoiser for progressive and interlaced video, developed by kassandro. The pack includes RemoveGrain.dll, Repair.dll, RSharpen.dll and their SSE2 and SSE3 versions.
A bug has been identified in the RemovegrainSSE3 module that causes a crash. Use SSE2 until it gets fixed. (SSE3 doesn't really gain you anything anyway.) It seems a fixed version has come out. See the links section below.
