Really non-standard ANIME

[colordog]

I know there's a bunch of threads concerning anime, but this is really driving me nuts! (Which reminds me of a great pirate joke...)

Anyway, I've been working on GTO (Great Treacher Onizuka). AVI2DVI states that it's interlaced, but of course we know that this is just a dirty, dirty lie.

Manually looking through the frames in GKnot shows that the introduction is nice and simple 3:2, so IVTC would be called for. However, the meat of the episode itself is all jacked up.

Some portions are interlaced at intervals 2:2. Some portions are interlaced 1:1. Some frames look to have multiple ghost copies of a moving figure. And, I don't know how they did this, but some frames are interlaced on the bottom, but not the top half of the frame! (see attachment for examples of 'multiple ghosts' and only parts of frame being interlaced)

With this kind of nightmare, is there anything to do besides FieldDeinterlacing?

There are a lot of progressive frames in there so you should recover them if you can. Use Telecide with pattern guidance and postprocessing followed by Decimate in one of its hybrid modes. You'll need blend=true on Telecide if you have blended fields as you suggest.

What is AVI2DVI?

I really like GTO by the way!

Hey, glad you enjoy GTO as well! I'm quite addicted to it, as well as several other animes. :)

I'm wondering if you'd be kind enough to spell out the AVScript of your suggestions - I haven't dealt with enough 'bad' anime yet to know how to turn all your suggestions into script. I'd really appreciate it!

[neuron2]

Well I haven't analyzed it so I don't know for sure what will work best. Also, when using the hybrid Decimate modes you need to empirically tweak the thresholds. We can start by trying this:

Telecide(guide=1,gthresh=30)
Decimate(mode=1,threshold=2)

The result will be 30fps. If you prefer 24fps, use mode=3.

If you'd like to post a link to a VOB fragment I'd be willing to develop a more targeted solution.

Sure, if you don't mind!
About what target size should I shoot for, for the VOB fragment?

[colordog]

Also, I've just realized I've never had to make a VOB fragment before... is there a thread that will teach me that?

Vobsplit from here (http://www.doom9.org/software2.htm#vobtools) might help you.

@sh0dan
Much appreciated!

I'm not sure what to do - the smallest filesize that VobSplit will allow me to make is about 13MB - but the maximum filesize I'm allowed to post here is 200KB. Is there any other place that I could post this for you?

If not then use WinRAR to split it into 1Meg pieces and mail them to me.

Since I'm a l0ser and don't have a site to put the file on, I've split it up and sent to your e-mail. :rolleyes:

I've received the file. Here is what I see:

1. There is no discernible pulldown pattern, so pattern guidance is not appropriate.

2. There is motion at 30fps mixed with static progressive frames.

3. There are a lot of blended and partially blended fields.

The medicine for this is very simple. Your script should look like this:

Telecide()

Yes, that's all. :-)

If you want to perk it up a bit, use:

Telecide()
MSharpen(threshold=10,strength=75)
Tweak(sat=1.3)

[colordog]

Wow... thanks a bunch!

I really appreciate it!

I'll try it and let you know how it turns out.
