problem ripping into a single .vob

Postby GH » Tue Jun 15, 2010 9:40 pm

i'm in the process of ripping a dvd, after it ripped i checked the directory to make sure it was done correctly, and there were several vobs in the folder instead of a single large one.

i had my settings as:

like the guide instructs (page 4). i'm a bit confused, did i do something wrong?

I didn't actually read that guide but I would assume your problem is that a VOB can't be larger than 1GB, it's part of the file system on a DVD and so VOB files get split to respect that.

oh, i don't understand then, because the guide even goes off to suggest that a fat32 hd wouldn't suffice because the file may be over 4gb, and that switching the file splitting setting to "auto" instead of the default would take care of the chance of it getting split to more than one file regardless of size.

VicBond's guide is really outdated and you risk to incurr into issues. Just use the avtech3 instead ─ it's not perfect, but it's still better.
As for VOBs, I'll have to echo Hatt on them being 1GB tops, not sure what he was referring to with the fat32 thing, unless perhaps he meant converting them to some lossless format which would take a lot more than that.

Why would a DVD be FAT32? That is a harddisk file system; it's not intended for optical usage. DVDs use a file system called UDF 1.02, which has a maximum filesize of 1GB while the max FAT32 file size is 4GB. DVD Decrypter will split your VOB so that it doesn't violate the DVD specification restrictions. Is there any reason you need it to be a single VOB file though? You can index multiple VOBs into a single d2v, and if you use DVD2AVI instead of shitty DGIndex, it will automatically load them in the right order when you open just one.

i think you misinterpreted me. i meant; in the guide it suggests to format whatever drive/directory you're ripping the vob to because the file may end up being over 4gb.

thanks for the link, i was looking for that guide but i couldn't remember the name.

anyway, i've been reading it for a while and i'm finally stuck somewhere.
i have my .d2v and .avs file, and then from
Using the DGIndex Project in AVIsynth:
down to the bottom of the page, i'm confused again. page the new terms that weren't explained earlier in the guide just throw me off.

Code: Select all
dgdecode_mpeg2source("your file.d2v")

Put that in your .avs file and save it.

somehow that was already in the .avs file, maybe because i used it from the amvapp, except i don't believe the "dgdecode_" was included.
mpeg2source("C:\Documents and Settings\Owner\Desktop\ef d1.d2v",cpu=6)

then i loaded that in avsp, then through that i loaded it into virtual dub, and i can see my dvd footage; it all looks pretty clean.

the guide says:

Is it Interlaced?

You probably know this already because DGIndex generally tells you if it is or not (Frame Type: Interlaced or Progressive). It is very important to look closely at the frame type when DGIndex previews and when it creates your project file as this will tell you a great deal about the way the footage is encoded. You will need this information to understand a lot of the things below as we will be comparing this information to what you can see in VirtualDubMod.

dgindex originally told me it was interlaced, but in virtual dub i don't notice any interlacing at all.

it seems the rest of the guide focuses on getting rid of problems with the footage like blending, interlacing, and telecined footage; what should i do after if my footage is already cleaned?

Leave out the CPU argument. The guide is actually HORRIBLE at explaining these things, but it sounds like you have progressive footage. If there are defects, fix them, otherwise leave it alone. You don't HAVE to filter it, it's a very optional thing. As far as organising stuff, leave your VOBs however, and just encode a nice fat lossless file to organise. You can then load it into your NLE in some shape or form.

i have 5 episodes in one .avs, because that's how much was on one disk, was too lazy to make them all separate.

but how exactly would i go about encoding them into a lossless?

Import the avs into virtualdub and make a YV12 lagarith, for example. Another solution which might actually turn out better for editing is making a lossless x264 and mux it into an m2ts.

Depends entirely on what editing app you use, but assuming it can handle lossless AVC, making a lossless m2ts file is a really good idea. Otherwise a lossless mp4 would do ok with x264, or YV12 lagarith AVI if your app uses VFW.

Nothing wrong with having your stuff in a single avs file; I have some 280GB y4m files with an intro, OP, 6 hour long OVA episodes, and the ED all together. RawSource() handles it really well and seeking is limited only by disk IO \o/
