    Problem:
    The video is "shaky" where the VOB’s are joined.


    1. I transferred a 3.25 hour, 2-tape movie from VHS to DVD via Toshiba standalone.

    2. I used the recorder to create chapters (scenes) so I could split the movie in two in order to maintain image quality and still be able to copy the movie from the recorder’s HDD to DVD-RW. I just copied half of the scenes to one DVD-RW and the other half to another DVD-RW. I did this because later, I want to use my computer and CCE to re-encode both to fit on a single DVD-R.

    3. Next I used Womble MPEG Video Wizard DVD to join the two DVD-RW’s into one large DVD file folder. I just imported all VOB’s and dragged them to the timeline. I then used Womble to make the DVD files. You can tell where the VOB’s were joined because a few frames are duplicated or repeated. The recorder did this.

    4. So I started over and imported the VOB’s from both DVD-RW’s again, but this time I used Womble to inspect, frame by frame, the last VOB from disc 1 and the first VOB from disc 2 because this is were they would be joined. I saw that the last VOB of disc 1 has 6-8 duplicates of a single frame before the last few frames at the end and the first VOB of disc 2 starts with a few frames that are just before the duplicate frames in the other VOB. I cut out the duplicate frames in the last VOB of disc 1 and played the new compilation with Womble. It looks great and you cannot see where the files are joined.

    5. Next, I used Womble, once again, to create the new, all-in-one DVD files. You can still see where the VOB’s are joined when played back on PowerDVD.

    6. I ran the files through Womble’s GOP fixer and even through VideoReDo’s QuickStream Fix but it made no difference.

    Anyone have any suggestions?

    Hi I would demux the 2 DVD using projectx ...(yes it can load vobs)

    And then join the the files using mpeg2schnitt ...

    But if you are going to put a 3h 25min movie on a 4.7G DVD you will get
    a very low birate avrage bitrate 2.6Mbit/s if you are using 192kb/s .ac3 sound then
    you will have approx 170 Mb left for system and menus... or are you using DL-DVD ???

    Important... when you encode the .m2v (I supose its interlaced) make sure if the clip is Top field first (TFF)
    or botton field first (BFF)

    Thanks Stars.

    I downloaded the applications you recommended and I will test them. Wish the help file for Mpeg2Schnitt was in English.

    Does demuxing help elevate problems when joining MPEG’s or is that just for lip-sync issues?

    I chose Womble because of the ease of use (not a pro here) and I have never encountered a problem with lip-sync and it too will demux if selected.

    I started over again and I used Womble once more but this time I chose a different spot to join the VOB’s and it worked out perfect! The previous joint was at the end of one VOB and the beginning of the other VOB (chapter point/scenes from the DVD recorder’s HDD). I don’t know if that was the problem or not.

    I also ran the files through DVD-RB w/CCE to fit them on one DVD-R. The quality is really good for squeezing that much on a single disc. Worth the extra time since the DVD-RB image quality is quite a bit better than the re-encode performed by the DVD recorder. The Toshiba DVR does a perfect job of joining scenes and a good job of squeezing the 3.25 hr movie on a standard DVD, but CCE does a better job of encoding. Of coarse the image quality of the original SP (4.6mb/s) DVD-RW discs is better, but almost no one will be able to distinguish between the SP discs and the CCE disc when viewing them on 27"-32" TV's.

    Next time I will pay closer attention to the length of the movie on the first cassette when transferring a “two tape” movie from VHS to DVD and I will set the bit rate accordingly on the DVR so no re-encode is needed. When I perform a rate conversion dub (re-encode) on the DVR, it softens/blurs the image but the normal mosquito noise or blocky artifacts are not nearly as noticeable as they are with most other encoders.

    How do I determine if the movie is interlaced and if it is TFF or BFF?

    Cheers,

    I suggest downloading the Teco Bit Rate Viewer from http://www.tecoltd.com for this. You don't necessarily need the commercial version unless you need to modify stream headers.

    Hi you can download a program called gspot ...

    often... (not 100 %)

    video clips from capturecard or DV are BFF

    .ts streams and vobs (from DVD) are TFF

  6. I had this same problem and resolved it by simply joining the VOB files together before using Womble. I use Simple File Joiner - it's fast and eliminates the problem entirely!
