    Hey, so I got a .vob file from a DVD & wantto svae that clip on my computer.

    Thing is the .vob file is a huge 1GB & is a very old & bad quality 20 minute clip of a very old cartoon show, so it's doesn't need to be anywhere that big in size.

    So I get the .vob file & want to shrink it to something resonable like 200MB.

    I used Ashampoo Shrink & Burn for it. I select the target output to 200MB & start converting.
    Well after 40 minutes the file is done converting & ends up only being ONLY 9MB & the quality is 10 times worse, totally unwatchable.

    So I try other .vob & mpeg files that are 170mb & convert them to 80MB & they all end up exactly like that target output perfectly. Yet when I try shrinking that 1GB .vob file to ANY size (20MB, 100MB, 500MB etc) the "estimated output size" window always shows up it as 9MB & that's what it converts to when finished.
    I tried everything, does anyone have any experience with Ashampoo Shrink & Burn?

    Or is there any other program soemone can recommend me so I can try to shrink that .vob file?

    Thanks in advance.

    If the source is already bad, shrinking it will make it even worse. If you want to reduce the size, might as well convert to MPEG4 with filters to clean up the source. I would use DVDRebuilder Pro with Avisynth filters.

    well I mean the source is bad in a sense it's an old VHS quality rip.
    It's still very watchable, but it looks to be like a 90-110MB quality type file.
    There is no reason for it to be 1GB, thing is Ashampoo will ONLY convert it to only 9MB, no matter what size I choose!

    I'm new to this & was wondering if there was another way/program to shrink a .vob/mpeg file?

    You may want to ask Ashampoo support why it's doing that. Isn't this product used to compress to CD?

    You can try DVDShrink (freeware) to compress using Custom Ratio option.

    I downloaded DVDshrink, but it doesn't open .vob files by themselves which is the only thing I have right now.
    Is there something I'm missing from DVDshrink?

    DVDShrink requires complete DVD files (VIDEO_TS.IFO, VTS_0x_0.IFO, and VOBs) to be able to import. So you're missing IFOs. In this case, you need to create a new DVD from your VOB file. Here's what you do:

    1. Demux the VOB file into elementary streams (video, audio, subpics) using VobEdit. Just check "Demux all Video/Audio/Subp streams". If you don't have subtitles, you don't have to check it.
    2. Using IfoEdit, select DVD Author -> Author new DVD.
    3. Import each elementary streams, select an output destination, and click OK.
    4. Now you can import this into DVDShrink. Choose Full Disc mode. Under Compression Settings, select Custom Ratio. Slide the bar to how much compression you want.

    man, I'm not getting anything to work.

    IS this the only way to convert .vob/MPEG2 files to .avi?

    Thanks for the program, but it does not recognize .vob files.

    Other than that the program is the easiest one I seen for converting videos.

    Anyway for it to recoginze .vob files?

    DVD shrink won't recognize a single .vob file, it requires the video to be DVD compliant which means .ifo and .bup files also need to be present. IFOedit can be used to create these extra files so that shrink will recognize and process the video.

    get ifoedit here
    http://www.afterdawn.com/software/video_software/dvd-r_tools/ifoedit.cfm

    Run that app and then choose to "create IFOs". It will ask you where you want the IFO files and the BUP files to go, just select the folder that your .vob file is in and then start the process. Once done you should have a working set of files (vob, ifo, bup) in the output folder that shrink will recognize and process.

    I haven't done it in a while, so I hope I'm correct with the process.
