Help with "True Lies"

[OvERaCiD23]

I am having one hell of a time with this movie (R1, WS). I'm encoding using DivX5, 2 CDs, 192kbps AC3. The movie is incredibly noisy and I can't filter it without losing tons of detail (mainly in the faces during close-ups, very blurred). My first attempt was using Convolution3D (0,8,8,8,8,8,3,0), but the faces were much too blurred (very noticeable during full-motion playback). I've then tried using DivX5s internal pre-processing (light-strong, nothing acceptable), much of the same results. I'm getting ~0.65-0.70 bits/pixel (30%-50%) compressibility checks, even with bilinear resizing! Has anyone had success with this movie? I've never had this much trouble with a film and I've done over a hundred different films!

I think you should use only 1Pass Quality Based !!! First I would set it to 100% if the movie is to big at the end you can go down with the procent !

With a compressibility of only 30-50%, using 1-pass Q2 would result in a massive file! Likely upwards of 2-3 GB, so not really an option. I'm trying some strong C3D settings, I've just never liked using filters to the point where they blur the image (doesn't really seem like I"m going to have an option though!). Right now I'm using (0,24,32,24,32,4,0) and am getting nicer results, can anyone suggest some settings for me to work off of?

Reduce your spatial filtering and increase your temporal filtering. The temporal part has the greatest effect on compressibility, the spatial filtering only causes detail to decrease rapidly.

First, I would start with Cnr2(), then for a very noisy source I would follow that with TemporalSoften(1,10,10) and maybe finish with SmoothHiQ(3,5,15,192,3). That's the combo I used on Dune (R2), which is by far the noisiest movie I've ever seen (it even has transmission interference lines through every frame), and it came out quite well denoised and no less unsharp than it already was (and it already was quite unsharp).

You can use avisynh's subtract filter to see the difference between the original and the filtered video directly without having to encode anything. That way you can adjust your parameters to better suit the amount of noise the movie has.
