Help with X-Remix Deinterlacing and Red Dot Crawl

[TrIfOrCe Of ShAdOwS]

X-Remix 5 DVD Set:

I've been in a bind with these DVDs for awhile now... I've tried tons of methods and I still can't get rid of the blending artifacts and the rad dot crawl. Maybe there isn't a way to get these perfect, but if there is a way to make them better I'd appreciate the help. I'm posting the best I've come up with so far, both the finished avi [divx for upload] and the original AVS. (btw I'm almost positive these are Hybrid Sources, but some parts may be able to be IVTCed)


Sample avi (after going through Avisynth and VirtualDubMod) [Yes this is divx, to fit in a reasonable file size, but I use Lagarith when editing. Just thought I'd say this since it is a little "muddier"on divx]:

http://www.megaupload.com/?d=6DXAFMV7 (Sorry, best way atm.)

AVS file:

LoadPlugin("D:/Program Files/AviSynth 2.5/plugins/undot.dll")
LoadPlugin("D:/Program Files/AviSynth 2.5/plugins/GuavaComb.dll")
LoadPlugin("D:/Program Files/AviSynth 2.5/plugins/Decomb521.dll")
MPEG2Source("D:/x_amv/1/x_1.d2v", cpu=4, idct=5)
ConvertToYUY2()
FixBrokenChromaUpsampling()
GuavaComb("NTSC", 95, 50, 100)
Telecide(order=1,post=0)
Decimate(mode=1,threshold=50)
Crop(8,0,-8,-0)
LanczosResize(640,480)
Undot()
AssumeFPS("film")

I know this is alot of filters, but I can't get the video much better than this...

I've been reluctant to post, since I thought I'd find the problem, but after a few months to a year I'm ready to ask for help.


I may just be trying to get it too perfect, but the dot crawl is kinda hard to miss. I've been trying to get the footage for this for awhile now, and I'd like to start making the AMV...

If you need .vobs, .d2ts, etc just ask... I can find some way of sending them.


Thanks Again.... ^_^

if a mod could, please move this to the avisynth section... Thanks. (you can delete this post after moving). If not I'll move it when I get a chance to get on my computer (I'm on my iPhone)

I'll take a look at it.

Right off the bat, I'm gonna suggest using Tcomb. it has dealt with the worst dot crawl I have ever seen (R1 release of FMP Fumoffu, see this for reference)

I didn't really see any problem with blending, but if you want to try another deinterlacing/IVTC set I'd recommend TFM + TDecimate (part of the TIVTC package, you can also get Tcomb from that site)

you can also nix those loadplugin lines since they are in avisynth's plugins folder

Undot is not meant to handle dot crawl. I think you're thinking of DeDot.

Whichever dot crawl filter you want to use, it should probably be tried <i>before</i> IVTC first.

Why do you have the line <b>FixBrokenChromaUpsampling()</b> in there? Replacing that and the line above it with <b>YV12ToYUY2(interlaced=true)</b> should upsample the chroma correctly. (And if it doesn't, then <b>interlaced=false</b> should.)

I haven't seen the Remix release of X, but I can tell you that the original contained illegal field order transitions. You can check this yourself by opening your D2V file in DVD2AVI/DGIndex, bringing up the statistics window, and scrubbing through the timeline. If the Info box keeps switching between saying T and B, then you've got field order transitions.
If you have this problem, then you'd better switch from Decomb to TIVTC (which Kariudo mentioned) for your IVTCing needs.

Actually it's top order throughout, but there are a few problems I forgot to mention:

Openings and closings are about 50% film hybrids.

And I can't remember, but something is different on Episode 0 as well... (the clip I showed you.)


Let me try a few methods on the 1st episode and see what I come up with... I'll post the results later today, or tom (I'm very tired right now, so I'm going to sleep)


Thanks again for the suggestions, I know the code I showed is very warped, but I try alot of stuff... It's just the standard avtech and avtechbeta methods aren't working for this source.

[TrIfOrCe Of ShAdOwS]

I think the closings are pure interlaced, sorry...

The openings are video 100%-around 88%


btw is there not an option to edit posts on this forum?

[TrIfOrCe Of ShAdOwS]

This doesn't make sense, now it says bottom field order....

I get different readings depending on which segment I preview...

[TrIfOrCe Of ShAdOwS]

Adding to that, I get different readings even if the new segment contains some of the 1st segment...

Yeah, sounds like you'll want to run that through TFM. If you then run the script and get an error message telling you that it created a new, fixed D2V file and that you should change your script to point to the new file, then you'll know that that was the problem.

I'm still getting dot-crawl from using various settings in Tcomb, but the TFM deinterlace seems to be working well, I just gotta tweak the Decimate to get the 24fps right. (it's mostly film, so it should be 24fps? I'm not sure...)
But Tcomb does minimize the dot-crawl more than GuavaComb, but it also has more artifacts... It is still present in alot of scenes, but is there even a way to get it all?

Sorry guys, I'm used to Java, not Avisynth, but I'm getting there. Thanks for the help.


Well I'm taking a break for awhile... ^-^
