So I am trying to remove heavy grain shown here: example 1 (http://img52.imageshack.us/img52/1990/ep18.png), example 2 (http://img7.imageshack.us/img7/1948/ep26.png), example 3 (http://img207.imageshack.us/img207/9554/ep34.png) (yes these are from the BD it self). I know that this grain is usually meant to be present, but this IMO is series has way excessive grain, and would look alot better if it had DNR applied slightly. Now I'm backing these up, so I can't really use a hardware DNR (like the ones that some BD players can do on there own). Here is an example of someone who has footage of what I am aiming to try and accomplish (http://www.youtube.com/watch?v=H3kRxWGX4L0).

Over all what I am asking is can someone recommend a plugin or filter for AviSynth that can remove the grain and produce the type of footage you see in the youtube video I linked. And if you have any other suggestions please post them.

MCTemporalDenoise(settings="medium",enhance=true,AA=true,edgeclean=true,flat=true)
FastLineDarken()

If the MCTD doesn't remove enough noise try increasing the settings (high or very high) or try adding "twopass=true" ...

I am sure there are more appropriate animation filters, I just throw MCTD at animation as they are generally just for the kids :P

My favorite combo is ttempsmooth() followed by fft3dfilter() or fft3dgpu() and gradfun3() + high bitrate to avoid banding.
