MeGUI x264 Conversion Failure

[Danette]

I have a difficult situation with about half the cartoons on a four-disc set. I have never had a problem with film types and other cartoons. However, this one has me stumped.

I rip the DVD with MakeMKV and then demux it, but I cannot convert the video to x264 with the desired script. I have also tried converting the MPEG file to an AVI, and even that doesn’t work. My x264 script is AnimeIVTC, but I have also tried QTGMC. With AnimeIVTC, I have tried AnimeIVTC(), AnimeIVTC(bbob=4) and AnimeIVTC(mode=2,bbob=4). Each time, MeGUI aborts with the errors listed in the attached log file. All of these scripts work on all other videos I have done.

I receive the same type of errors and aborted processing when I use QTGMC with all the defaults. However, when I set QTGMC’s mode to progressive, as in QTGMC(InputType=1), it will process the file, but the resulting video is very dark.

Additionally, as you can see in the images of various info generators (although the link doesn't seem to be showing), there is mixed agreement on exactly what some of the video parameters are. I can tell you that there is definitely a 3:2 telecine pattern.

Dropbox 10 seconds of the original unaltered video so we can take a look.

For instance, you can use DGIndex to get the unaltered 10 seconds.

Created with Avidemux in copy-only mode.

Thanks

There is no need for any deinterlacing or IVTC, you need to remove the duplicates.

[Danette]

Please take a look at "Sample 2" that I just uploaded. Apparently, Avidemux did not copy it as it said it did, which is typical of what I'm finding with this video: processing it is frustrating many of my software processors.

Sample 2 is an AVI created by Vdub2 and shows the interlacing artifacts, which can also be seen in the original (don't ask me why Avidemux didn't show it).

If it is from a DVD you should use DGIndex or MPEG_Streamclip.

I could not find a sample 2.

Forget "Sample 2". I have used MPEG Streamclip to create "Sample 3", which can be found here:

In that sample, you will see the interlacing artifacts, at least when using Vdub2 to walk through it.

That source is not interlaced nor telecined.

That's odd. So, you cannot see the combing effect in VDub2?

Why would DGIndex report 29.97 fps and the combing be visible if it were not interlaced?

[StainlessS]

Dont know but some things viewed with DirectShow use some kind of auto deinterlaced (if it is switched on, dont remember where to switch it off),
I had someone (a few years back) wanting to deblend blending that was produced within directShow (clip itself was not blended).
Perhaps Cary Knoop is viewing in some directshow viewer.

Upload a screenshot of what you see.

[gonca]

Sample 3 is 23.976 fps with pulldown (2:3) to make 29.97
Just IVTC it to make it original framerate

[Cary Knoop]

Someone show me a screenshot that shows a single interlaced frame.

Here is one using Vdub2:

gonca is correct. It is 3:2 soft telecined. So if you honor the pulldown you will have 2 out of 5 combed frames.

Yes, thanks. That worked and confirms that the original file is interlaced.

However, I still have the very dark output problem when applying QTGMC(InputType=1) after the TFM script and I do want to use QTGMC to get all the image improvement aspects. The darkening effect can be seen when comparing these two samples:

Yes, thanks. That worked and confirms that the original file is interlaced. Sample 3 is NOT interlaced. It is telecined.

Also, it is 100% soft telecine, so you do not need to use TFM/TDecimate. Just use Force Film mode in DGIndex. It will be way faster as well as more accurate (adaptive field matchers can make mistakes, especially for anime).

Yup: I often mistakenly call it inerlaced when it's actually telecined. Virtually every DVD I rip is telecined and I say "interlaced." Will try to stop this.

Good tip on the "Forced Film" feature.

[Cary Knoop]

Soft telecined means the actual frames are not telecined, there is no need for any IVTC.
