VirtualDubMod constantly rendering and won't stop

[mirkosp]

Well, cpu=6 is way too much. Generally speaking cpu=4 can be over necessary too, actually. It's probably best to keep the cpu parameter at 2 tops if really need be, or better yet just use cpu=0 and leave the deblocking to better filters, like for example Deblock_QED. That is, if the source needs deblocking to begin with.

Firstly, multiple plugins provide mpeg2source, so you need a specifier in all example scripts.

You don't if you only use DGDecode. It's pretty fruitless to assume that everyone still keeps the 7 years outdated Mpeg2Dec3 around anyway. It's not even included in AMVapp anymore either. So they'd have to be getting it from somewhere else, putting consideration of such in their hands only.

yeah, I guess cpu=6 might be a bit high.
Yet, I always valued the cpu parameter because it uses extra information from the .d2v index, which would make it better for post-production than downstream filters. I can't remember where I heard that though. Does it even matter with newer filters? I've never used Deblock_QED.

[mirkosp]

I find Deblock_QED to be really good when I need to deblock, but I guess you should compare by yourself the results of cpu=X vs deblock_qed or other filters, since some things are just about personal preference in the end. Some people prefer a sharper image with a few blocks here and there, others prefer a slightly blurrier one in favor of a lack of blocks.

How about the updated-in-January-2010 version of mpeg2dec3? There are 4 or 5 forks of the original mpeg2dec3 that I can think of that are still actively used and developed, moreso than DGIndex which has been dropped by it's developer. There are even active forks of mpeg2dec2.

@Phantasmagoriat: leave the CPU argument on default, if your source needs filtering there are better ways to do it, and most of the time it really doesn't.

Links? Hitting Google turned up nothing but the one that was left to rot in 2003, nor did anything turn up on Doom9 or Doom10, or on the main AviSynth External Filters page, which was last edited 4 days ago - it still lists Mpeg2Dec3 as deprecated. In any case, no version of Mpeg2Dec3 is included in the AMVapp, and unless the powers that be suddenly decide to put one back in, there's no point in addressing it in the guide or examples, since most users only rely on what the app gives them.

And considering DGIndex's latest update is from March 6th, 2010 (with a secondary fix for Win2K users on the 16th), I highly doubt it's been dropped. DGAVCIndex was dropped due to a GPL violation issue and all the remaining stuff concerning H.264 and VC-1 are handled by the NV tools, but if that thread is any indication the DGMPGDec package remains active.

I figured I'd use this thread since I'd already started it and piggyback in a quick question. What do I do if I rip a DVD but the audio doesn't come with it? I used DVDfab and got great image, but I actually need the audio in this instance. I tried it with DVD Decryptor from the old AMVApp setup and had the same issue. I thought it was because it was a trial or something, but I dunno.

Would anyone know what I could do?

[Mister Hatt]

You're decrypting it wrong.

@Qyot27: I didn't know that Donald updated it in March, last I heard he'd dropped it. I can't provide links for the forks as I have no clue, I get my stuff from other people mostly. My copy of mpeg2dec comes from timecop, it's about the same in capability as dgdecode's mpeg2dec, only a bit slower and works better with the weirder things I come across in MPEG2-TS streams that would break dgdecode.

When you are indexing in DGIndex, make sure "Audio → Output Method" is set to "Demux All Tracks." That way all the audio tracks included will be ripped out. "Disable" won't output anything, "Demux Tracks" requires you to specify the IDs of the tracks you want (ID of the track is the first number in the lines of the audio box when you hit "File → Preview", so 80, 81, and 82 in this example, and you can specify the IDs by going to "Audio → Select Track(s)"), and "Decode AC3 track to WAV" will do exactly that.

don't use any variant of virtualdub. virtualdub is crap, avisynth can be converted directly into a format non linear video editors can open through framecasting, it can be preview through ffdshow's avisynth support and makeAVIs is better than VFAPI, once you have made your amv using framecasting, you can re-encode your source files if you're happy with the preview's quality to mpeg-2, and then use that to make h264 encode for your amv.
