How to DENoise?

[Remyisme]

I've dloaded VirtualDub - Mpeg2 and MSU Denoiser v1.6.1 but i don't understand how to use it.
i've opened my file than went to "video" than "filters" and selected the filter but i don't know what to do next, please explain how to use it.

[Remyisme]

I also would like to know how to deinterlace, please.

Best way to learn filters is to use them, IMO anyway. Watch both screens and see if you get what you want. Then optionally see if there's an equivilent for Avisynth, & if so, try that.

Personally I am rather found of the Convolution3D filter for AviSynth.

This is a "video noise" filter.

I wrote a mini-guide on it a while back.

There are several posts in the RESTORATION FORUM where Satstorm and myself discussed some VirtualDub noise removal settings. They work quite well, and were not the ones you tried.

Also, why deinterlace? If this is for a DVD, do not do it.

I tried the trial version of NeatVideo and was amazed. I own and love NeatImage and was happy to see a video-ized version show up.

www.neatvideo.com

Unfortunately the free version is limited to 3 minutes and 640x480, and it applies a logo. Cost to remove these limitations, $99. I'm curious as to what's the next best thing....

I tried NeatVideo too, and was impressed, except of the speed of 1-2FPS. It gave better results than Convolution3D. But they stole the idea from the freeware program called Neat Batch. The author of Neat Batch was really mad in another forum. Personally I'm not going to pay for NeatVideo, because of this, unless they give the original author credit and royalties for each NeatVideo sold.

I'll just stick with Convolution3D and despot/depan, which is the best freeware you can get and it's faster than NeatVideo. I've tried cnr2,denoiser, and others, and Convolution3D beats all IMO.

FWIW, I have a tough time agreeing with your post.

All the "Neat Batch" person did was write some DOS batch files that called NeatImage to do 99.99% of the heavy lifting. It's certainly no freeware program, it requires a commercial license of NeatImage. NeatVideo and NeatImage are made by the same company. IMO, it's the other way around.

As a fan and long-time registered user of NeatImage for my photography work, I've been looking forward to the same folks creating a video version. I just wish it were, maybe, $50.

Convolution3D does work wonders

If I recall correctly I used DeSpot once on a VHS video that was recorded from a cable TV station with a lot of "static" in the image (cable yes but bad reception on that channel) and it cleaned it up amazing well ... was really incredible!

The "static" was like whitish "speckles" all through-out the image (think of LD rot) and it took like 90+ % of it away.

Hi Fulci,

Just checked out your "mini-guide" on noise reduction with avisynth and it looks very promising for my particular problem, but I'm having a problem with V-Dub mod accepting the script. Basically, I'm following directions to the letter and, when I try to get VDM to accept the script file, I get the error message:

Avisynth open failure:
Convolution3D supports YUY2 color format only
(file path and name)

The problem is with line #4 which, in my case, is the one starting with "odd=SelectOdd.Convolution3D" (I'm not cropping).

Kind of stumped here because I'm definitely not an avisynth guy, and I was hoping you might offer some insight. I've copied the full text of my own script below. Please hit me back if you get a chance and wouldn't mind setting me straight. Thanks very much!

Zeek




LoadPlugin("Convolution3d.dll")
avisource("C:\Documents and Settings\Administrator\Desktop\tester clip.avi")
SeparateFields()
odd=SelectOdd.Convolution3D (0, 6, 10, 6, 8, 2.8, 0)
evn=SelectEven.Convolution3D (0, 6, 10, 6, 8, 2.8, 0)
Interleave(evn,odd)
Weave()
DoubleWeave.SelectOdd()
ConvertToRGB(interlaced

@Zeek

Try this here script:

LoadPlugin("Convolution3d.dll") 
avisource("C:\Documents and Settings\Administrator\Desktop\tester clip.avi")
ConvertToYUY2(interlaced=true)  
SeparateFields() 
odd=SelectOdd.Convolution3D (0, 6, 10, 6, 8, 2.8, 0) 
evn=SelectEven.Convolution3D (0, 6, 10, 6, 8, 2.8, 0) 
Interleave(evn,odd) 
Weave() 
DoubleWeave.SelectOdd() 
ConvertToRGB24(interlaced=true)

Please note the last line is if you are using it with TMPGEnc Plus ... if you use CCE then you don't need that last line of the script.

Thanks, Fulci.

Actually, I just did that very thing (ConvertToYUY2) - except did not add the interlaced=true line at the end. I'm messing with some 5 sec test clips right now. Will re-do them with the new(est) script and re-post what I see in a few minutes.

Thank you very much for replying.

[Zeek]

Ok,

Tried the new script. Not doubting you for a moment, my friend, but I'm not sure that I see much of a difference. I think this is probably because of the fact that the light quality is exceptionally poor, and also because of the red hue from lighting that is inside the building on this particular (wedding reception) video.

I'm not one to give up easily, but I'm thinking this one might be a tough nut to crack. The test clips are about 4 MB each, and I'd be happy to post them if you or anyone wouldn't mind looking and this forum will allow it.

And, just to clarify: I AM supposed to be simply dropping the script file into TMPGEnc or any MPEG encoder, correct? Just wondering, because the lack of any difference makes me wonder if I'm somehow missing something with this.

Thanks again..

Regards,

Zeek

If you have a website you can post your clips there then post a link here in the thread so I and/or others can download them.

That is correct. What I've done in the past is open the script up with VirtualDubMod then open up the file with no processing into another VirutalDubMod and switch back and forth to see the difference.

Ok..

Unfortunately, I do not own webspace, so posting it that way probably isn't going to fly unless I can find a volunteer.

FWIW, this might be an excercise in futility, but I prepared a couple of screen shots that I could show you - a before and after, and also a few other before/after ones of screeshots from avi files that I've taken after messing with another filter that I found right here . I seem to be having the most sucess with this particular filter.

Overall, I've played around with temporal and spatial filtering a bit - and, IMHO, it seems to me that spatial filtering does more and does it quicker than the temporal stuff. Might be just my personal tastes, or maybe this particular video, but that's my $0.02. In any case, at the end of it all, I'm still not really sure if it is worth it. Too much spatial and the thing starts to look like a retarded oil painting and, with temporal filtering, you obviously start to get that wacky embossing sort of look. At the end of the day, I might be better just taking the noise.

Anyway, if we can figure out a way, I would very much like your opinion on any of it. I've been sitting here and trying to figure out how to upload multiple images to one post, but am not having much luck at that. Do you have an email address or something that I could send the images to? I could PM you, or whatever you like.

Hi could you tell me more about desot/depan ?
Some example in conjunction with C3D ?

thanks, Nik
