    How do I convert vob to any file format that is recognized by adobe premier, videowave or any other editing program?

    Demux the video to m2v using VOBrator, and the audio to wav using DVD2AVI. Premiere will import them as long as you have an mpeg2 codec loaded.

    Have you heard of any problems with operating vobrator? I downloaded, extracted, launched and opened a vob file -- after completing the open and extraction, the program crashed and closed. Now I can't get it to open a file withoug crashing. I'm running XP. Could that be it?

    Researching my issue, I found a thread that asked:

    The thread read:
    I'm glad to see I'm not the only one with this problem here: How would I do anything like taking JUST a particular scene/trailer/anything from a DVD and make it an AVI or Quicktime.

    I've already used virtualdub(no VOB import),Smartripper(copies VOB),Clad DVD XP(crashes), cladbrc(does nothing), VFAPI reader(no VOB import, wants DV2

    Now I know a lot of people are in love with DiVix, BUT it's just another compressor in the class of MPEG type compressors. These compressors do a really good job of making video files REALLY small and still look good AND play full screen smoothly. However I DON'T want small. I want the biggest most uncompressed file on my hard drive I can get(fromDVD). Yes I know DVD is already compressed, but compressing again is not a good idea. I need AVI with no compression or with Ligos compresssion. I need a REAL AVI...all AVIs end with ".avi" not ".mpg".

    The answer came back:
    Uncompressed AVI.. YUV24 or something similiar. Too lazy to calculate, but I would say it will take around 40 to 70GB per movie to store it as uncompressed AVI.

    I don't understand what this means. Can you explain please.

    It's talking about converting the DVD to uncompressed AVI. Don't do it... you'll need enough hard disks to sink a ship!

    VOBrator is rather wobbly, isn't it? VOBedit will also demux the video/audio give it a try.

    VOBrator really is "wobbly". After loading and reloading half a dozen times, I finally got it to "work". Then, after 7:48:32, it came up with an error message. I could have died.

    I'll try VOBEdit now. Thanks.

    I only have 5 minutes or less to convert from VOB to AVI. Isn't it worth it to keep the highest quality possible, since it won't take up a huge amount of space?

    What is the simplest way to do this? Is VOBEdit the best program? I read a little about SmartRipper. Is that good?

    I had somebody put some 3/4" video on DVD to make it easy to get into my computer--not knowing the problems I'd face. Would I get better quality if I had it converted from 3/4" to DV tape? Then I still have to rent a deck to capture it.

    Here's something someone wrote on the Adobe Premiere forum, saying you can just rename the VOB files and import them into Premiere. Sounds too easy to be true.

    "simply re-name the file from *.vob to *.m2v the steams appear simular, just the extention. Some software cant be fooled, you may also have to chage the file name from VTS_01_1.vob to Movie01.m2v and so on."

    I very much doubt that renaming the .vob to .m2v would 'fool' Premiere. VOBs can contain more than just a video and single audio track.

    I used Premiere to edit a DVD just yesterday.

    1. RIP will DVDdecrypter.
    2. Created a d2v project and WAV with DVD2AVI
    3. Created a pseudo AVI using VFAPIreader
    4. Imported the pseudo AVI and WAV into Premiere
    5. Encoded the video/audio into AVI using the Microsoft DV codec.

    Works just dandy.

    Rgds,

    Thanks for listing the steps you took. Could you give some more detail?

    For instance, why use DVDdecrypter for Step 1 and then switch to DVD2AVI? I thought that also converted DVDs (or whatever ripping consists of).

    What is a d2v project?

    Do I really need a pseudo AVI if my project is short? Wouldn't I get higher quality with a full size AVI? How can I get that?

    Besides Premiere, I have Pinnacle Studio 8, which will edit MPEG-2. Are there fewer steps to get to MPEG-2 than AVI? Does it compress the file more than going to AVI? How would the quality compare?

    Q. why use DVDdecrypter for Step 1 and then switch to DVD2AVI? I thought that also converted DVDs (or whatever ripping consists of).

    A. It's just another example of achieving the same result. DVDdecrytor (or any other Ripper) is required to decypher the data, then I used DVD2AVI to convert the audio to wav since Premiere will not import ac3 audio.

    Q. What is a d2v project?

    A. Output of DVD2AVI that represents the vob video so that apps such as TMPGEnc and VFAPIreader can read them.

    Q. Do I really need a pseudo AVI if my project is short? Wouldn't I get higher quality with a full size AVI? How can I get that?

    A. Like we already discussed, demuxing the video to m2v/wav is probably the simplest, but this was just another way to do things. And yes, if your video is short, by all means use uncompressed video.

    Q. Besides Premiere, I have Pinnacle Studio 8, which will edit MPEG-2. Are there fewer steps to get to MPEG-2 than AVI? Does it compress the file more than going to AVI? How would the quality compare?

    A. If Studio 8 handles MPEG2, then try it. Premiere has some trouble (at least with ver.6) with MPEG2, due to the small number of keyframes I think.

    Then, if I were going to a regular AVI, would I do the first two steps--DVDdecrypter, then DVD2AVI--then go directly to Premiere?

    If I were going to edit in MPEG-2, would I still use those two programs or something else?

    Almost. You also need to either:

    1. demux the video to m2v, OR
    2. Create a pseudo AVI (video only) via VFAPIreader.

    THEN you can read the m2v or pseudo AVI, AND the wav file into Premiere.

    OK, I do the first 2 steps and then demux the video to m2v using VOBrator--or VOBedit? I don't want to use something "wobbly." After that, go to Premiere or Studio 8?

    What is m2v? Something that Premiere sees as an AVI but isn't?

    I was looking at afterdawn's downloads. It says vStrip v0.8f css is the best DVD ripper in the world but complicated to learn. I may not be ready for complicated, but best in the world sounds good. What's the practical difference between best and the rest?

    They're all much the same in my opinion. Try them. Best you be the judge.

    Will DVDCutter Stream and Mp3CDWav Converter 3.2 convert VOBs to AVI in one step? Does it convert both audio and video?

    I have done this and have run into a problem which I can not solve. When I rejoin the exported Premier-edited video (as an authored VOB - I use Spruceup), back into the sequence with the other VOBs (that make up the movie) the WAV audio fails to play. Using VOBEdit I can see that the unedited VOBs use AC3 for their audio, while my Premier-edited video outputs its audio as a WAV (PCM) file. Is ther any way that I can play both WAV AND AC3 audio on the same DVD - or is there another solution to this problem?
