i'd like to encode the lord of the rings 1 double dvd into three ogm files. i already tested it with two ogms, but the picture quality is really too bad. the problem I now have is that i don't know how to cut the two vob files of the dvd so that i get three new vob files of the same size.

what is the best quality I can achieve with divx 5.02 pro and what are the settings for it?

Well, i'd use such 'technique':
- demux and merge ac3's,
- extract both vobs to HDD,
- open first vob in VdubMod through avisynth, append second one, (or maybe it's possible to do straightly in avisynth script),
- do 2pass encode with xvid specifying target video size (2100M - ac3size), or 2pass divx with bitrate, calculated from desired video size / length,
- join video with ac3 using VDubMod (I'm not sure if it can split resulted ogm, if not then use ogmtools).

or better check this.

thx, i'll try as soon as i have the time to do it

the thread of the doom9 forum is very helpfull to!

uhmm, what about 2/3vobs? just rip with smartripper both dvds and then paste those into dvd2avi (all vobs) -> gknot -> and so on...
edit: yes it will work, tested.
edit2: of course dvd2avi is also where you demux or decode your audio in this case (still my favorite/simplest solution)

(or maybe there is some new tech to avoid dvd2avi this days?)

Hi smok3. You could play around with VirtualDubMod; its intended goal is to add that sort of functionality to VirtualDub, but it's in moderately heavy development. I still get better results using DVD2AVI > VFAPI > VirtualDub, myself.

vfapi? sounds like you never tryed gordianknot and the avs system? (mucho faster)
wasnt aware of the vdubmod project.

btw: i did a nonextended version of lotr 2cd rip some time ago, with xvid and ogg into ogm container, problems were:
- the ogm muxer wasnt able to cut where i wanted to (only possibility was file size)
- xvid picture is still greenish/bluish
- ogg doesnt sound good at all (first i thought it is a muxing problem), 2 many high freq. (oggenc v1 at -q4)
- i burned into 2x800 megs cds (what a dumb mistake) and now the 2nd cd is hardly readable...
- the subtitle system was not able to antialias corectly.
anyway, it was an experiment and iam sure all the tools got better so far.

edit: about the doom thread:
- dj bobo is correct
- i dont understand the Acaila and his:
since i cant remember the case when keyframes were not exactly at the film-cut points... (talking about avi=divx+mp3 or ac3)

I tried it a little while back, but I often like to apply VirtualDub filters and postprocessing, as well as specialized resizing (some filters seem to result in better effects when placed before the resizing, and some after...). Sounds odd because of how picky I am about my music, but sometimes I like to have a movie/television episode playing in the corner of my screen while I work on another project. For example, I did an encode of the extended version of "Fellowship of the Ring" at 112x48 resolution just for fun - it fits easily on a 3" CD. My younger brother goes farther than that; he's been known to answer the question "What are you watching?" with "Star Wars Episode I: the Icon."

Edit: I'll be the first to admit this is pretty useless, but in terms of "neatness factor" it feels more like "Floggy video."

I guess its in the eye of the beholder, I actually did a two CD rip, and thought it was decent. However, I also ripped all 4 commentary tracks, and the subtitles, and muxed them in the ogm. To get the audio small enough, I had to do some serious low-lowpass, but retain the 48kHz sampling rate (thanks to oggdropxpd!).

Another way to save space on these is to CUT the two (= 26 minute) credit chapters. It helped disk 2's bitrate substantially.

Asynth can operate in yv12 (directly feeding video to encoder), bypassing colorspace convertions: vfapi does yv12 -> (yuy2?) -> rgb, and filters, similar to VDub ones, can be applied from avisynth directly.
And IMHO there's no need to use automation tools such as GK if you're not doing mass backups. Just single avs fed to vdubmod should do the trick.

what gknot does for me is (after audio part is allready done):

- correct aspect ratio calculation
- calculation of bitrate
- calculation of croping with the best possible or no ar distortion
- testing of the compressability and of course the final resolution which is offten based on the compresibility test (also taking into account that x and y should be dividable by 32 or at least 16)
- auto generation of the avs script from all that data
- iam sure i forgot something...

from there i prefer manual work in vdub so gknot does not start or control encoding of audio or video.

@smoke3

you mentioned the subtitles. as they were not antialiased well i suppose you encoded them as part of the pictures of the video.

oggmux needs .str files for subtitles. when i use smartripper i only get .rawsub files which cannot be opened/used with oggmux.

now to my question (@all):

how can i get this .srt file?

SubRip will get you a .srt file...

Go to www.doom9.org to the Guides section and read, read, read...

Oh, and you might want to try watching your movied with ffdshow instead of the official DivX filter... I like the neat "on-the-fly" noise filters, film filters, sharpening filters, adaptive postprocessing, bicubic resizing, and also supports subtitles of many kinds... so you don't need your player to support them.

Good luck!

does subrip work as well as smartripper, so that it can replace the latter?

i suppose i can get the ffdsfilters from doom9.net...

nope, they are not burned into the pic, i should said it is a filter-playback-overlay problem of the ogm ds filter or something and they are stored inside the ogm as well (at least in my experiment), and i dont remember the subtitle procedure iam afraid (check doom9 guide for that). (subrip is something to rip the subs from vobs, not something that would replace smartripper)

yeah, you're right. i already had to realize it at the doom9 site...

DVDs have become so cheap that the whole process of migrating a DVD to multiple CD-Rs seems very foolhardy. My time is worth money and why bother with this xvid and divx stuff when the output quality is still very subpar unless you want to use like 3 CDs per DVD. Then you have to swap discs like every hour. Forget it! Not worth the hassle.

cos its fun?

you can make an asx playlist for example...

But you still have to physically shuffle media in and out of your CD-ROM drive. I could see divx-encoding your DVDs if you own a humungous hard drive and want to store compressed films for easy viewing (like keeping MP3s on your hard drive for your music albums) but you still need a lot of space to store, say, 50 divx movies.

what i do is copy the files (from multiple cds) onto hd just for playback, it doesnt take more than 10 minutes for a 2cd rip and another minute to make that asx file (if it is not allready there). 50 divx movies is not a distant future, i mean can you buy a drive smaller than 60gb this days? (it will become even worse -> why divx when you can store original dvds on your hd?)
btw: lotr extended is on two dvds as well (dont you just hate swaping)

Like 35-50 gigs (for avg movies), when everybody keep talking about how cheap is HD space nowadays?
My friend with whom I happen to ICS my modem connection stores on his 80G HDD shipped with his pc (bought about year ago) about same amount of movies and he takes it like natural thing these days.

@M: you been running vdubmod on xp? (kinda crashy here), idea seems nice and complicated as well, did a lil test with similar resize filters -> 'vdubmod internal vob reader' against 'avs->ordinary vdub', its like 8fps against 13fps on my system. B)

@smok3: To tell the truth, I haven't used VirtualDubMod that much... the earlier versions were more than "kinda" crashy for me. Sorta wonky, I would say. But I notice there have been several revisions since I was experimenting with it. I still get the best results with ordinary, plain ol' vanilla VirtualDub in XP.

i use divx 5.02 pro two pass encoding (full resolution) with all pro-settings like psycho-visual enhancements (strong), pre-processing (normal), quarter pixels, gmc... [naturally ogg vorbis sound] if the length i choose for one cd does not exceed 1h20' you will not see any artifacts at all! i have to apologize that the brilliance of the pictures looses a lot. the genuin mpeg2stream has much more brighter colors.

the use of this procedure is to collect as many good (best) films as possible on the harddisc, so that you always have the possiblity and a large choice to watch the film you like! most films are not bigger than 2h hours, so that they can be put on one cd and have an acceptable quality. as hard-discs evolve continously there will be more and more room for more and more films!


thats not true. i thought the same once with my mp3 collection when i had a 17g harddisc and only a few original cds (and no internet connection! ) now i've got 18gigs mp3s and 6,33oggs (btw. OGG VORBIS RULEZ!!!) and i still expand my collection. so, with films it'll be the same: you'll get addicted to collecting them B). i know many other guys who have the same addictive personality as me and fill one hard disc after another!

Oh man... all i have to say is, try Koepi's latest XviD developer ("unstable") build. Arguable, but it's -better- than DivX, i've tried it on various things, and it just simply is better. Has chroma information motion detection, quarter pixel resolution for better motion estimation, and b-frames of course..
My suggestion's enable those 3 (and don't enable GMC and lumi-masking, and use H.263) and set max b-frames: 3, b-frame quantize ratio: 200, b-frame quantizer offset: 100, and see for yourself. More stuff and different configs can be good too of course, so you can experiment too.
Don't want to mess with 2-pass? So try 1-pass - quantizer with quantizer 3 for some trailer/s or clips or stuff and you'll see how nice it is. (at Doom9.org you can find many stuff, so no need to keep on writing about this here)

i would go for 3cd rip with divx5.02 pro with b-frames and nothing else for lotr extended.
sk1: why didnt you post your xvid settings on doom9.org then?

i wanted to encode my dvds with xvid, but i compared quality between divx (pro with all features i mentioned) and xvid (a version of july, i think. divx was clearly better than xvid...

but i like open-source projects very much, so i'll give xvid a second chance. but i don't like "unstable" versions...

all the stuff i need for xvid can be found on doom9's site?

maybe rip some 'opensource' movies then ...

Use Iago's Two-Pass guide for the best settings to use with XviD
Latest version can be find at the bottom of this thread

all movies i rip are made open source by myself!

I noted that after installing fddshow, and it happened to be a decoder issue. If you use fddshow, there is an option (miscelaneous) to change IDCT, the default option (simple 16683) produced those tint problems, switching to both Normal or Xvid IDCT solved it.
