NP! Also, I'm using ffmpeg CVS from yesterday:
yuvdenoise --version
INFO: [yuvdenoise] ========================================================
INFO: [yuvdenoise] Y4M2 Motion-Compensating-YCrCb-Denoiser
INFO: [yuvdenoise] ========================================================
INFO: [yuvdenoise] Version: MjpegTools 1.6.2
yuvdenoise: invalid option -- -
Y4M2 - Denoiser Usage:
===========================================================================
-t <0...255> Y Denoiser threshold
accept any image-error up to +/- threshold for a single
pixel to be accepted as valid for the image. If the
absolute error is greater than this, exchange the pixel
with the according pixel of the reference image.
(default=5)
-u <0...255> Cr Denoiser threshold
(default=5)
-v <0...255> Cb Denoiser threshold
(default=5)
-c <0|1> Chroma-flicker reduction
(default=1)
-l <0...255> Average 'n' Y frames for a time-lowpassed pixel. Values
below 2 will lead to a good response to the reference
frame, while larger values will cut out more noise (and
as a drawback will lead to noticable artefacts on high
motion scenes.) Values above 8 are allowed but rather
useless. (default=3)
-m <0...255> Average 'n' Cr frames for a time-lowpassed pixel.
(default=3)
-n <0...255> Average 'n' Cb frames for a time-lowpassed pixel.
(default=3)
-r <8...24> Limit the search radius to that value. Usually it will
not make sense to go higher than 16. Esp. for VCD sizes.
(default=8)
-b <x>,<y>,<w>,<h> Set active image area. Every pixel outside will be set
to <16,128,128> ("pure black"). This can save a lot of bits
without even touching the image itself (eg. on 16:9 movies
on 4:3 (VCD and SVCD) (default=0,0,0,0)
-L <0...255> Set luminance contrast in percent. (default=100)
100 = no effect
-C <0...255> Set chrominance contrast in percent. AKA "Saturation"
(default=100) 100 = no effect
-S <0...255> Set sharpness in percent. WARNING: do not set too high
as this will gain bit-noise. (default=125)
0 = no effect
-F Force deinterlacing. By default denoise interlaced.
-f Fast mode. Use only Pass II (bitnoise-reduction) for
low to very low noise material. (default off)
-p <0...255> Pass II threshold (same as -t).
WARNING: If set to values greater than 8 you *will* see
artefacts...(default=4)
