the ivtc tutorial is great but...

[wim]

about a year ago when i was just starting out i had a problem, the section "SOME TIPS FOR MAKING SENSE OF WHAT DVD2AVI TELLS YOU" says

use the following .avs to check the frames in Virtual Dub:
LoadPlugin("mpeg2dec.dll")
LoadPlugin("Decomb.dll")
MpegSource("clip.d2v")
Telecide(post=false)

and i could never get this to work. one day i noticed a discrepancy in a gknot-created avs and so realised MpegSource needed to be Mpeg2Source. which seems obvious in hindsight, but not so clear to a n00b who didn't know what an avs even does.

manually checking the frames in Virtual Dub is probably the most useful step to creating a good looking avi (i bet i have fielddeinterlaced a progressive dvd for one of my earlier rips), so it may help newbies a lot to realise sooner that they can do this.

Hi-

You're right. Sorry to have to mislead you on that one. I'll have to scold hakko504 over that. :) Not that I haven't proofread it 50 times.

But that was written back in the dark ages of AviSynth 2.0x, and now we're up to 2.51 and Decomb's up to Decomb500b15 , and it should be:

LoadPlugin("mpeg2dec3.dll")
LoadPlugin("Decomb.dll")
Mpeg2Source("clip.d2v")
Telecide(Order=1,post=0)

But we'll update it one of these days. Thanks for bringing it to our attention.

it is ridiculous to apologise since this is free volunteered help! really the ivtc tutorial is still the most helpful document i have ever seen about divxing, and then 100fps.com.

hm mpeg2dec.dll is still in my gknot folder. i assume these are both vob decoders, but what do they do differently? and what does Order=1 do for telecide (the parameter is not mentioned in the decomb readme)?

where to get this decomb500b15? i looked at donald graft's page and could only get 410b4.

thanks manono

Hi-

If you like to use the latest encoding methods, then you switch to VDubMod for your encoding, install the latest AviSynth 2.5.2, use the MPEG2DEC3.dll, and use the latest Decomb for your IVTC. The major benefit is a considerable increase in encoding speed. The information you'll need to make the switch, and most of the software you'll need can be found in the YV12 FAQ (http://forum.doom9.org/showthread.php?s=&threadid=37276). You can get the latest Decomb Here (http://forum.doom9.org/showthread.php?s=&threadid=54456).

Order=1 means top field first. You now have to set the field order yourself, whereas before, the earlier versions of Decomb did it for you. 410b4 can still be used, though, if you prefer. For most (if not all) DVDs, Order=1. It's only when you slice up the vobs that you might find Order=0 (bottom field first). This might occur, for example, if you're encoding some anime episodes separately that might be all in one PGC (all together in one set of vobs), and you cut them up in DVD2AVI.

hi,
you can get decomb 5 beta 15 here (http://forum.doom9.org/showthread.php?s=&threadid=54456&highlight=decomb+beta)

as you said, mpeg2dec and mpeg2dec3 are both mpeg2 decoders. actually mpeg2dec3 is simply a further developped version. It has a few new features (e.g. YV12 support) and should be way faster, especially when using fast recompress in virtualdubmod (complete YV12 conversion)
