New IVTC for Avisynth

[Guest]

I have just released the first really good version of my new IVTC for Avisynth. It performs extremely well with default parameters, even on difficult anime such as "Cowboy Bebop". Please be sure to get Decomb Version 1.5 if you have already obtained an earlier version.

Here is a filter chain to use for tough anime:

LoadPlugin("decomb.dll")
AVISource("bebop1.avi") [or mpeg2source]
ConvertToYUY2()
Telecide
Decimate15
FieldDeinterlace

Note that the last step just catches any stray combed fields that might stray through due to input clip problems. It DOES NOT TOUCH clean progressive frames and can be omitted for clean source material (Cowboy bebop is not clean!). The help file in the distribution gives extensive instructions and tips. I think you will find the results to be truly stunning.

MMX/SSE optimizations are under way.

Tom Daniel (manono) assisted extensively with testing.

Get the software at http://sauron.mordor.net/dgraft/

Feedback will be gratefully received.

Im going to try & add this to DVD2AVI if thats ok...As with everything you create Donald....Very Impressive

Cheers,

What would adding it to DVD2AVI entail? Do you just invoke the DLL?

My only concern is if there would be proper credit for my work and that of Tom Daniel who was an important contributor.

Also, the optimized version is under development. Would you be able to upgrade to that easily?

Donald -

Congrats, I'll check that out.

If you are branching out into Avisynth filters you might want to consider the leverage of also adding the DVD2AVI versions and it could certainly use your talent. DVD2AVI may be going to CVS/Sourceforge. See the DVD2AVI CVS thread.

Thanks Donald.

I've tested Decomp and the result was better than any other IVTC-filter I've tested so far. Great !

Thanks once again

Impressive! I tested it on a short part of Gasaraki and it performes extremely well, the image quality is higher than with GreedyHMA! Decomb also doesn't produce choppy output, playback is very smooth.

Good work, I'm waiting for MMX and SSE optimizations

Good stuff -- Decomb 1.5 seems to handle some cases that trip up my current favorite, GreedyHMA. But it does seem to have trouble with mostly static scenes where the only movement is an actors lips, during dialog. GreedyHMA is really good with that.

I'm glad to hear that this early version is producing good results. But there is still a lot of room for improvement. So, daxab, can you please make a short clip available to me that shows the problem?

[daxab]

I trimmed things down and recompressed using HuffyYUV. You can get it here:

(=EDIT: Dead link removed=)

(Please let me know when you have the clip so I can free up the space.)

I hope this helps. Also if you want me to do any beta testing for you I'd be happy to -- I am IVTC'ing noisy source material (you'll see what I mean) every week.

Thanks for your work, I'm really looking forward to trying it out!

I've released a new version of Decomb that does better with small moving mouths, etc. Get Version 1.6 at

OK, there is a problem. After some time of encoding, Windows closes all applications reporting there is too little virtual memory. This happened a several times.

Having a look into the task manager, I see the swapfile is constantly increasing. I have made a swapfile of 700 MB now (with 512 MB RAM) but this still happens.

This is definitely related to Decomb, because it didn't occur with GreedyHMA. It would be great if you could fix that, Donald, as the quality of Decomb is very impressive.

[Nic]

Sounds like a memory leak, but I'd never accuse Donald of anything so scandalous

Erm..I'd add DVD2AVI to allow DVD2AVI to have some proper IVTC code. I don't use it personally (I live in UK & only rip PAL stuff) but many people have asked for IVTC in DVD2AVI. You could have any sort of recognition you wanted (Splash Screen, MessageBox, something in the about, etc)

Unfortunatley it wouldn't be easy...id have to do a lot of fiddling with the code (& I know the source is pending so I guess i'd have to wait (there isn't a nice easy ->GetFrame(n) in DVD2AVI that I can use, (but im trying to make DVD2AVI more AVISynth friendly)

But if you'd really rather that I didn't try to add it to DVD2AVI than I more than respect that...

Take Care,
-Nic

Version 1.7 with the fix for the memory leak can be obtained from my web site http://sauron.mordor.net/dgraft/

Sorry for the inconvenience. I'm normally not like this. :-)

Hi neuron2 aka Donald,

It seems to work very well indeed, and I have added support for it in dvd2svcd. I wanted to ask you, if it was ok with you, if I add Decomb to my software bundle. You will ofcourse be given full credits for the software and I will include the entire Decomb package.

"OK, like, gag me, where's the attachment? I feel oh so newbie. :-("

Not your problem. Attachments have to be approved due to the the problems other boards had with cracks and such. Sorry for the cramp.

[Tri]

It works now! Great job!

[Guest]

DON'T USE THE ATTACHED ONE!!! It is bad, bad, bad.

Use the one from my web site. Thank you.

Question: What will Decomb do in NTSC IVTC mode (Telecide.Decimate15 and possibly FieldDeinterlace) if given interlaced source? In other words, if I have some source that is 90% real film, but 10% video or whatever, what will Decomb do with that 10%?

[Guest]

@dvd2svcd

That is OK. But realize the package is evolving fast. Keep an eye on it so you always have the latest and greatest. :-)
