Thanks Rafael
I am pretty sure as well that yuvdenoise will work only for a limited
colorspace.
there is the option of y4mdenoise though. Wil try and see.
Otherwise combining image magick denoising or greycstoration

something maybe to think about for the future of cinelerra and / or Lumiera
cheers

Hi E,
For the yuvdenoise, try storing the y4m file and check it's header using a
text editor. In there you can check the colorspace, but I bet yuvdenoise
only handles YUV colorspace.
For the ffmpeg only solution, this one is the only that have chances in
doing what you want.

Hi there
A tad off topic sorry but it can probably help others exporting through
y4mpegpipe
First : I was wondering if anyone made a comparison between denoisers
(e.g. yuvdenoise and hqdn3d) ?
Second : can they process RGB data ?
For say if I use a quicktime RGB 24 mov file as an input (or a sequence
of TIFF files)
ffmpeg -threads 2 -y -i - -vf "format=rgb24, slicify=32" -f yuv4mpegpipe
- | yuvdenoise | ffmpeg -i - etc ...
I am probably reading way more data than processed
if I use
ffmpeg -vf "hqdn3d,format=rgb24, slicify=32" -threads 2 -y -i - -b
220000k -pix_fmt yuv422p -vf "pad=1920:1080:240:0:black, slicify=32" -r
24 -vcodec dnxhd -threads 2 fichier.mov
Am I really filtering RGB data ?
Thanks a lot
E
