I'm looking for a noise reduction filter to use with iuvcr. I have been using Virtualdub, but it's performance is iffy. Iuvcr allows me to capture without any frame loss, but doesn't have a native filter to clean up the noise in the line.

Since switching to iuvcr, I deinterlace with Virtualdub, frameserve to Tmpgenc, and run the noise reduction filter in Tmpgenc. It bumps the encoding time quite a bit, though.
