Denoiser.

[Jeremy Duncan]

What is the best Denoiser Avisynth Plugin ?
Link and instructions appreciated.

I read about hqdn3d.
Please link to the best version of this, and tell me the best setup for it.

[Jeremy Duncan]

I'm going to use it in FFDShow and Media Player Classic.

Please don´t ask what is the best.:readrule:
There is no best denoising, everything depends on your own view and the source you want to denoise. It makes a big difference if your source is analog or digital, good or bad quality, anime or natural and if you like smooth pictures or detailed pictures more. So please give us some more information about it that we can help you.

I'm going to use Media Player Classic to Play DVD Movies.
And I'm going to use FFDShow to improve the picture.

The Movie is going to play from the DVD Disk.
I'm not going to rip it to the HDD.

I'm looking for a denoiser that's better that the Blur & NR Denoise3d
in FFDShow.

I understand hqdn3d does just this.
Is this the best one for what I need ?
Please tell me the best settings to input in FFDShow for hqdn3d.
And please link to the best version.

Unfortunately, you still have not answered the appropriate questions.

Is it live action (with real people recorded on camera), or artificial (CG or anime)?

Is the source high qaulity or low quality? DVD does not tell us much, as I have seen very poor film-to-DVD transfers.

How much detail is in the image? Is it very sharp and precise, or is it a little soft around edges?

Providing a small unprocessed sample for the experts here would be good if you want the best results.

Both

Is the source high qaulity or low quality?

I think it's high quality.

How much detail is in the image? Is it very sharp and precise, or is it a little soft around edges?

It's pretty detailed.

I'm not sure if it's legal to post pictures.

Here's some of the Movies;

Ghost in the Shell 2
Serenity
The Fifth Element
Pitch Black
Tears of the Sun
Equilibrium

Please tell me the best settings to input in FFDShow for hqdn3d.
And please link to the best version. After you were explicitly instructed to not ask what's best, per forum rules, you've now done it again -- three times! Thus, you are struck for a rule 12 violation.

Please read and follow the forum rules. Thank you.

[Jeremy Duncan]

I understand.

If you want to use ffdshow as a postprocessor during playback for good quality sources the deblocker seems to be more important than the denoiser to me. If you already use the deblocking algorythm of ffdshow and still want to use the denoiser, yes I prefer to use hqdn3d too. If your pc has enough performance you should set hq=true. The default setting are really to strong. especially the temporal filtering shouldn´t be used so strong because for good sources this creates more artefacts than it will remove. Values around 2 seem to work nice for most sources. For anime you can go a little bit higher (until 3) and for natural good quality sources you can set smaller values (near one) or better use only a light deblocking.
I don´t know if hqdn3d has changed the last version of ffdshow, but I don´t think. I don´t see a reason to use an older version.
I hope this helps a little bit.

[Jeremy Duncan]

Thanks. This is my new setting.

HQDN3D(1.3,0.9,0.9,0.9)

[Jeremy Duncan]

What deblocker in ffdshow ?
What's it called ?

:thanks:

[MOmonster]

You find it in the decoder settings under postprocessing. It is also a automatic mode possible. But if you use avisynth and not only the internal ffdshow filters of course you are not limited to these ffdshow filters. You can also use the deblock() function from the dgdecode dll and if you use mpeg2source to open the vobs over d2v you can also use the postprocessing of this function.
Also for your denoising you could use other fast filters like removegrain or removedirt. FFT3D gives excellent results but will be to slow for realtime playback.

[Jeremy Duncan]

:thanks:

[techmule]

Try this, gives good results with speeed.

Removegrain(mode=2)
STMedianfilter(3,3,1,1)
