View Full Version : Having a Lot of Trouble With Nandub

Ok, so I have the Return of the King retail DVD here with me, and I'm using it to fiddle with nandub as I want to explore other options beyond DVDx and DVD2AVI encodes.

It's 3h30m45s, which divides quite nicely into 3 x 1h10m15s pieces.

I first made a DVD2AVI project, and demuxed the AC3 audio as per the tutorial for nandub on this site. I didn't force NTSC FILM 23.976. I just saved the project after my prefunctory OGO resizing and cropping (Which I'm not sure I had to do).

With the project saved, I ran the IVTC process with TMPGenc on auto and the IVTC to 23.976 went smoothly. I saved that TMPGEnc project.

I then imported the TMPGEnc project with VFAPI Converter and made it into a readable AVI for Nandub. The result was a 2.29GB AVI file.

I transcoded the audio from 448kbits to 192 via besweet. The audio is ~296mb. I then used nandub's bitrate calculator to find the bitrate of 3 x 700 with the 296mb audio. It came out to be about 1239kbps.

Then what I did is followed all the settings in the nandub guide, and used the suggested values (I'll edit my post and list them if you need the settings I used).

I ran a resize filter of 640x262 on precise bicubic, and ditched the black borders of your standard NTSC DVD with a crop.

When I go to hit F8 to make the first pass's stats file (For the second pass), it reads a few minutes of it and then says I'm out of disk space. Except I'm not, because it's not really saving anything?

I thought maybe I would like to try encoding only a piece of the file by setting the encode range, but that didn't work either.

When I did another project with the exact same settings, except using a smaller sample file of 5000 frames, the encoding process made that 5000 frames into 4GB.

So what I need to know is why my filesizes are so ridiculously off, why can't I encode only a sliver of the full project, and why aren't my passes working correctly?

I've triple-checked my settings. If anyone needs more explanation on something, I'll be glad to oblige. Thank you for your time. :)

Nandub, eh?
Does anyone still actually use that? :confused:

I don't know the rules on legality around here (I read the rules, but I don't know if I can mention it in a vague passing) but the, er, "Underground" still seems to use nandub and their encodes are of higher quality than I can seem to produce with DVDx or DVD2AVI.

If anyone has some alternate suggestions as to how to produce better quality with DVDx, DVD2AVI, or another program, I would be glad to hear them. I've been working with XViD/DiVX since 2002, and every now and then I get the bug to learn new techniques and spend hours fiddling with video samples from my DVDs to see how codecs have improved and if I can do better encodes.

I got bit by the bug today.

I think the majority of people making quality backups nowadays use either Gordian Knot or AutoGK, and those use VirtualDubMOD for vfw encoding/muxing
My surprise comes from the fact that Nandub is almost solely used for DivX 3.11 encoding, and let's tell the truth, DivX 3.11 is extremely obsolete in face of the latest DivX 5 and XviD codecs...

I agree completely. I wouldn't deal with anything less than a modern release of XViD (.0.9.x) or older than DiVX 5.1.x.

I was just fooling around, mostly, seeing nice results from it and trying to see if I could emulate it.

I'll give GK a try and see how it works, thank you for your help. :D

//EDIT:

I did a quick'n'dirty play with AutoGK. I'm in love.

Make sure you keep up with the latest GK builds.

Not with respect to noisy sources. But ok, the OP was talking about DVDs here.

As a fanatical fanboy and defender of Nandub myself, my advice to you is to stop using Nandub and start using Xvid. :)

I use nothing but XViD. ;)

to answer the initial problem, althought using xvid / divx 5 might offer a far better solution now...
4gb sample is probably due to a missing codec. (meaning divx 3,11 not being installed or not recognized)...
the same goes for the first sample if the 'no avi' option was not enabled for the first pass...

No they don't use nandub for encoding, nandub is only used for muxing.

You don't even need nandub for muxing anymore, Virtualdubmod can do that and so much more.
