Noise Reduction

[lineb]

hi all,
I'm newbie and I'm not english, so excuse me for any mistake.

I'm try to backup the film "Mongol" with x264 (with avidemux svn), but the source present block/noise.
I tryed with the noise reduction but seems to produce any benefit.

I used the default option except some variation:
-Two pass average 1500kb (only for this test)
-Motion Estimation Method: Uneven Multi-hexagon
-Fast P-Skip: unchecked
-Trellis: 2
-Max Consecutive B-Frame: 5
-Use as Reference: checked
-B-Frame Direct Mode: Auto

-Noise Reduction: Off for the first video test.
1500 for the secnd video test.

The noise is much present on the first and last scene.

Noise reduction Off: http://web.tiscali.it/lanarkband/1.mkv (size 6.7mb~)

Noise reduction 1500: http://web.tiscali.it/lanarkband/noise1500.mkv (size 6.7mb~)


How do I reduce this ***** noise?
Any suggestion?

Thanks in advance.
Simone.

x264's noise reduction is designed to be extremely fast and fit in-loop with the encoding process--not to be very good.

There are many slower (but much better) external denoisers if you need to clean up a seriously noisy source. For example, fft3dfilter (or fft3dgpu if you have a fast graphics card), dfttest, etc.
