Cdeblend

[MOmonster]

Because of many changes and a different development, Cdeblend is now a seperate avs function. This release works far better than the last version, has new modes and more parameters to tweak the detection.
You need masktools (included in the zip) to run this function.
Everything is updated, also the readme (maybe with many mistakes). Hope the function is useful against many blending problems. :)

You can download the R_pack here (http://forum.gleitz.info/attachment.php?attachmentid=83974&d=1160722387).

Edit:
Small update. Omode 4 is added. You can use it to get a better feeling for the right konfiguration.
Edit2:
The final Mrestore version is included into the zip.

[MOmonster]

Cdeblend is updated.
- Dmode 2 and 3 are removed. The other modes works clearly better.
- Average isn´t needed anymore for dmode 1
- the motion thresholding is improved
- smaller code, but no speed or quality changes

FixBlendIVTC and Crestore will be also updated soon. Then I want to concentrate on another project.

[MOmonster]

And another version is out (0.95b).

Changes are:

- added mil parameter for motion-influence-limiting
- faster and better dmode 1
- new dmode 2 for low motion blend detection (slower than dmode 0 and 1, but faster than old dmode 1)
- updated to newest masktools version (2 alpha 26)

[MOmonster]

Cdeblend is now finalized.

There are many many changes from the last version:
- better compatibility to decimators (much better, but still not save)
- new parameters and much more tweakable
- new quality mode
- new omode that includes the possibility of the Cdeblend modifications (but works better)
- the dthreshing is now able also for the other omodes

There are still some more ideas about this in my head, but if I´ll plan to release another version it will be a plugin and no function anymore.
I hope this function is helpful against some of your blending problems.

Cu MOmonster.

attachments were up for approval so I posted direct link.

[digitalone]

thx a lot max24 and bengali thug :)

Edit: do you guys by any chance have documentation of this function?

[chipzoller]

Could someone take a quick look at this sample (http://www.megaupload.com/?d=K5JXTTY1) I've uploaded. It comes from a documentary DVD produced by the BBC. I'm not sure what has been done to screw this up and therefore cannot figure out which of MOMonster's scripts (including restore24?) would work for this since I'm not familiar working with field blended materials. Any help is appreciated.

Its in the Cdeblend.avs file.

[MOmonster]

First look with virtualdub looks like a normconversion. You need to restore the pal source with repal or restore24(Didee's function:) ).
Next week I think I`ll release Mrestore 2.0 that should also do the job (current is not so good for ntsc sources).
The spider gives less motion without a good fluency, so repal can make problems. Restore24 works also better for pal than for ntsc sources (but still mostly better than last official Mrestore).
You should test what works best for you.
I'll test my current version and reply next week.

[chipzoller]

Thanks. I'll try both and see what looks better...that is until your Mrestore 2.0, but for future reference so I can learn from this source, can you describe what's happened here in a somewhat step-by-step manner? For instance, was it shot in pure interlaced PAL then fieldblended up to interlaced NTSC? Or was it shot in film, pulledup to PAL then back to NTSC? Etc. etc. What is the definition of "normconversion (normal conversion?)" I notice that when stepping through some fields have been duplicated and some fields are blends. I'd really like to know how to describe how something like this was created. It sure would be great if there was a guide to all the different types of blendings and possible restoration methods complete with video test clips and avisynth functions/scripts.

[~bT~]

^ i'd love to read an explanation too. :)

[MOmonster]

Sorry I lost the sample on my usb stick, but I downloaded it again and will test it.
I was asked a lot for such a guide or bigger explanation and I allready give the answer that the next release will have a lot more description of this problem.

[chipzoller]

Thanks. I'm interested, of course, in exactly what is going on with my sample, but also from a broader perspective in knowing how to detect blended fields, how the clip got that way (i.e. standards conversion, etc.) and best options for restoration. I look forward to what you have to say.

[outcomes]

can anyone tell me where i can get mt_masktools???fileter:rolleyes:

[MOmonster]

@outcomes
You can find the latest version in this (http://forum.doom9.org/showthread.php?t=98985) thread.

@chipzoller
I mean a guide for these blendconverted sources and not a longer desciption of my function.:rolleyes:
Sorry, I think I won´t complete the description this week.

Edit: Could you please read this (http://forum.doom9.org/showpost.php?p=998764&postcount=122) post. Maybe you have a low motion pan in your source.

[chipzoller]

I mean a guide for these blendconverted sources
Yes, I mean a general guide to detecting any sort of blended fields activity and not just specific to my source (which I'm only using for testing/learning purposes).

Maybe you have a low motion pan in your source.
But the entire source displays this pattern of field blending. In any case, I'll try this new version.

@MoMonster, this new version of mrestore seems to work quite well on my posted sample. If you've checked this yourself, what is your opinion?

[MOmonster]

@chipzoller
Yes on your short sample it works quite well for me, also compared to restore24 and repal, but currently there is no code for really low motion pans with hardly detectable blends. Don´t if you have such scene in your source.
And of course I also mean a general guide for a lot of typical conversions.:rolleyes: Let me finish my work, then you can ask for more if it is not complete enough for you.:)

[chipzoller]

MOmonster

Understood. But are you saying you will eventually add some code for low-motion pans? What would happen if there was a scene or two that did have low-motion pans and you used your script on them?

Also, is there such thing as a restore function to take (my sample, for example) 30i back to 50p? Or is this limited to a restoration of 25p?

Let me finish my work, then you can ask for more if it is not complete enough for you
Yes, of course. I must have misunderstood your last post. I look forward to any explanations you can offer! Thank you.

[MOmonster]

Yes I want to add such code for the final release, but I just have no samples I can test with. I think I will create myself. I´ll find a pal source with such pans. It´s just some extra work.
If you use Mrestore on such scenes, the output could be not total fluid, not as smooth as the original pal source, but this won´t have any effects on the other scenes.
I have never seen a 30i source normconverted from 50p, maybe that´s why I don´t know about any function for this case.

[chipzoller]

@MOmonster

Any luck in coming up with a semi-tutorial on field-blended and other conversions that call for special restore scripts? I'm very much interested in learning how to detect and process these.

[MOmonster]

Good that you remind me. The german version is ready since some weeks. I have a lot other things to do, especially in the university, it´s time for the tests. Also the translation needs more time than I thought. Please have some patience, results will come.

[elguaxo]

Any links for the german version?

Thanks.

[MOmonster]

I can upload it the next time I have an Inet-connection, if wanted (doesn´t have the file with me).

[elguaxo]

I would be interested!

[MOmonster]

Ok, I uploaded the german one here (http://www.file-upload.net/download-344096/guide.zip.html). The English version is still not ready.

[elguaxo]

Thanks!

[chipzoller]

English version ready yet?

[MOmonster]

Currently I´m working on Mrestore v2.1. Guide will come with this new release.

[2Bdecided]

Sorry for this late reply...

Thanks. I'll try both and see what looks better...that is until your Mrestore 2.0, but for future reference so I can learn from this source, can you describe what's happened here in a somewhat step-by-step manner? For instance, was it shot in pure interlaced PAL then fieldblended up to interlaced NTSC? Or was it shot in film, pulledup to PAL then back to NTSC?

The source would have been 25p, probably film. Remember for the PAL market, made for TV content is routinely shot on film at 25p, not 24p. Most natural history (wildlife) content shot by the BBC Bristol natural history unit used to be film, but HD video is now more common.

There is no 50p motion in there to "restore", though you could try to create it (fake it with mvtools) if you wanted to.

Remember too in PAL countries we don't usually think about pulldown/up. You take 1 film frame, it becomes 1 video frame. That's it. It happens to sometimes be transmitted as two interlaced fields, but it's still 1 film frame - and telecines and editors usually honour the field dominance (always frame-change or cut before the top field). In the digital video world, you don't have to do anything to it to get it to or from that state.

(There are exceptions, e.g. mistakes which shift it all by one field, so a single frame contains half of each of two film frames. Against BBC and ITA guidelines. Horrible, but fixable).


It's possible the PAL>NTSC conversion took the PAL video, treated it as if it was an interlaced source (which it wasn't) and field blended it to NTSC. It's also possible the conversion took account of the fact that the source was progressive, but decided to create blended fields anyway - AVIsynth's convertFPS will do that for you - or at least it will give you blended frames which you can SelectEvery into fields. Gives a slightly smoother look than hard 3-2 (or the more complicated equivalent to get 25p to 60i).


I know it's an experiment, but if you actually wanted this footage, you could just buy the "PAL" version (if available) - none of this crappy processing, and slightly higher resolution too.

Cheers,
David.

BUMP: Just checking back to find out your status of MRestore 2.1 (and, of course, the guide in English!).

[MOmonster]

Since some days I´m back to work on the function and the guide. Will be ready very soon. Give me one more week.

[Adub]

Looking forward to it. I have some really messed up sources I want to test it out on.

[MOmonster]

Could you upload a small sample. Then I could test it with the current alpha version and maybe tweak it a little bit more.

[MOmonster]

The first english guide version can be downloaded: here (http://www.file-upload.net/download-487075/guide_eng---framerate-conversions.zip.html) (still some mistakes yet, but most are removed;))
A testversion of mrestore v2.2 is allready running on my pc, but I want to do some more tweaking and add some more features before I'll release it (in the next days).

[elguaxo]

:thanks:

[Alain2]

:thanks: +1

[Adub]

Sorry, I had the sample at my brother's house, and it worked great there.

[chipzoller]

Any news on your Mrestore work?

[MOmonster]

I updated mrestore last year, december (v2.3). Currently there is no further development on mrestore.

[bokonon]

Hi, noob here,

I want to restore a field blended NTSC source which was transferred to PAL DVD (25fps). How can i use Mrestore? I have copied the files in the zip over to my plugins directory but i can't seem to find any instructions on how to use it to restore to 24fps + deinterlace.

[thetoof]

Isn't that a restore24 case?
