Hybird film/interlaced. Mostly interlaced

[mandeep145]

hello respect-ed's. I love Ripping with Megui.I am trying to rip a movie with Megui.but when i click on Analysis for source type I m getting Hybird film/interlaced. Mostly interlaced. i don't know how to handle this type of source. please teach me.

don't trust on auto analyzing,it usually gives you the wrong choice :)

So then what to do. please tell me.

Analyze it with your eyes and brain. See #1 and #2 here:

What does MeGUI suggest? I assume it's NTSC?

What does MeGUI suggest? I assume it's NTSC?

yes it's ITU 16:9 NTSC (1.823169).

[hello_hello]

I meant what de-interlacing method does MeGUI suggest to use as a result of it deciding it's hybird film/interlaced, mostly interlaced? What's it adding to the script?
Not that it's possible to know without seeing the source video if it's the best way to do it, and living in PAL-Land I'm the last person to offer advice on NTSC video, but if you copy the de-interlacing part of the script and paste it here I'm sure someone will be able to tell you what it means, what will be done to the video as a result and, whether it at least makes sense.

No NTSC experts offering a hand? Well even though I should be the last person to offer NTSC advice, until someone else comes along......

Assuming MeGUI got the analysis correct I'd just go with the method it chose. The video would be mainly 29.970fps interlaced which MeGUI will de-interlace to give you 29.970fps progressive. If there are some parts which are really film but have been converted from 23.976fps to 29.970fps using Telecine (http://en.wikipedia.org/wiki/Ivtc#Frame_rate_differences) I assume they'll be converted to 29.970fps progressive too but I don't quite understand how de-interlacing in the script actually does that.

Edit: I found the reference to hybrid=3 in the readme file. I'll go out on a limb and guess that tdecimate will be using it's default mode of zero (as none is specified) plus hybrid=3, so for any parts of the video which are pure film it'll remove the duplicate fields to return it to the original 23.976 frame rate and then add extra frames while blending them with existing ones to give you 29.970fps progressive to match the frame rate of the bulk of the video. Or something to that effect.

Anyway, unless an NTSC expert comes along to suggest if there's a better way, I'd let MeGUI pick the de-interlacing method and use the "Preview AVS Script" button to see what the video will look like. Play a few sections, maybe move through some frame by frame to see if it looks okay. Or try one of the other "Hybird film/interlaced. Mostly interlaced" options to see if they look any better or worse. If they all suck then maybe MeGUI is getting it wrong, but it's probably not. You should be able to use any of them because I guess they all do the same thing in the end.

These are three types of deinterlacing MeGUI lets you choose for the above type of video. The following is what it'll add to the script for each. Hopefully an NTSC expert will come along and can explain to mandeep145 exactly what each does and what the differences are. I'd be kind of interested to learn myself.

LoadPlugin("C:\Program Files\MeGUI\tools\avisynth_plugin\TIVTC.dll")
tfm(order=1).tdecimate(hybrid=3)

LoadPlugin("C:\Program Files\MeGUI\tools\avisynth_plugin\TIVTC.dll")

LoadPlugin("C:\Program Files\MeGUI\tools\avisynth_plugin\TDeint.dll")
edeintted = AssumeTFF().SeparateFields().SelectEven().EEDI2(field=-1)
tdeintted = TDeint(edeint=edeintted,order=1)
tfm(order=1,clip2=tdeintted).tdecimate(hybrid=3)

LoadPlugin("C:\Program Files\MeGUI\tools\avisynth_plugin\Decomb.dll")
AssumeTFF().Telecide(guide=1).Decimate(mode=1,threshold=2.0)

It's probably some Indian field-blended garbage and it's nothing an automatic analysis can diagnose and correctly handle. You'd have to do it yourself (manually) as it'll most likely need unblending. Is it this film:

A short 10 second sample from the source, one with steady movement, would help us to better tell what you have.
