Problem re-encoding MBAFF

[mugz8391]

I purchased a new music video recenty and I'm trying to make a backup using MeGUI / Avisynth and XMedia Recode. The source looks HD but the re-encodes all have clearly visible combing effects. I've tried using a de-interlace filter on both with no effect. I'm setting the bit rate at 10,000 and I've tried h.264 and h.265. Part of the problem is that the disk itself is comprised of videos from several different live concerts and some of the songs are a combination of progressive, interlaced and MBAFF.

I'm very much a novice at this and have had good luck in the past with both programs - this disk has me stuck.

Can you provide a sample ?

Your explanation doesn't really make sense: MBAFF and PAFF are both techniques to encode interlacing; PAFF encodes the full frame content in interlaced mode regardless of the content, whereas MBAFF encodes areas (in slices of macroblocks) depending on which scan type (progressive or interlaced) returns the more efficient result.

A sample would indeed be important. Deinterlacers only work reliably for native interlacing, where the recording time progresses linearly from one field to the next. But there are also norm conversions with blended fields or even worse mess.

This is a 15 second clip, untouched from the Blu-Ray:

Looks telecined to me. Try IVTC instead of a deinterlacer.

yes I thought the same. This seems to work:

lwlibavvideosource("C:\Users\davex\Desktop\clip-2.mkv")
tfm().tdecimate()

Hey that's awesome guys! Thanks!

Hello again,

I am still having some problems but wanted to wait till the weekend. I uninstalled and reinstalled AviSynth and MeGUI and ran update - just to be sure I had everything current and this is the avs file I am trying to use:

LoadPlugin("C:\Program Files (x86)\MeGUI\tools\lsmash\LSMASHSource.dll")
LWLibavVideoSource("F:\Video\CLIP-2-002.mkv")
tfm().tdecimate()

and the error I get is: There is no function named tfm

I checked and it appears that is part of TIVTC which is in the plugins directory - can you tell me what I need to do?

Try explicitly loading the plugin like you are doing with LSMASH.

Oh yes, I should have known that - thanks so much!
