  1. I recently starting ripping DVD's, at the moment I'm working on an old PAL DVD.
    But I've noticed a problem, I'm seeing these kind of horizontal lines when there's movement on the screen, really obvious if you pause it.

    To start with I was using EaseFab DVD Ripper and I was advised to try the deinterlacing effect, but that's made no difference.
    Next I ripped them with MakeMKV then used Handbrake afterwards, again I used deinterlacing in handbrake, but the results are exactually the same as EaseFab.

    Is there a way to solve this problem? It's not that bad, but if there is a fix I want to find it, but on the flip side I don't want to spend hours tearing my hair out over nothing.

    With EaseFab and Handbrake, I'm converting them to .mp4.

  2. Make available a 10-second piece from the source DVD, one that shows the problem.

    You can cut a piece using the [ and ] buttons in DGIndex. After isolating the short section, go File->Save Project and Demux Video. Upload the resulting M2V file. You can do something similar using MPEG2Cut2.

    'The Jaggies' ripping/copying should not create this, if it does not already exist on the DVD

  4. Sorry, I've had no luck using either of those programs.
    But here's a screenshot if that helps.

    Not good enough. You opened a VOB in DGIndex and used the [ and ] buttons to isolate a small section (after using the slider to get to the section you want)? If so, what's the problem? You'll have to do better than 'no luck'.

    But here's a screenshot if that helps.
    Not a bit. It's already been deduced that what you described is interlacing, but it's important to know what's causing it. Then we'll know how to treat it. I am surprised, though, that Handbrake couldn't deinterlace it.

  6. By "no luck" I mean that DGIndex keeps crashing whenever I select a .vob from a DVD. The few times that it hasn't crashed, it says "No data. Check your PIDS".

  7. Did you decrypt the DVD to the hard drive first? As you should have?

  8. I don't know much about DVD ripping.

    Are you saying I need to rip the DVD but keep it in .vob format? How do I go about that?
    Quote Quote  
  9. O.k think I got something.

    I ripped this with Easefab using vob pal settings.

  10. The frames are interlaced, top field first, but it's encoded progressive. AssumeTFF().QTGMC() will give you smooth 50 fps video.

    Sorry to sound so clueless, but I am. What program do I use and how I go about using those settings?

    Not to worry. We were all clueless to begin with. Jagabo is recommending Avisynth, a script-based media rendering engine.

  13. I find it hard to believe that a Red Dwarf DVD would have been incorrectly encoded progressive.

    It may not have been, since he said it was 'ripped' at 'PAL VOB settings' using something I've never heard of. The impression I get is that it was reencoded.

    Edit: But I could be wrong. I just looked it up and, apparently, it can be made to just decrypt.

    In future if you see such pattern then you can use some deinterlacer (yadif or similar) - your source is interlace and your display is progressive - on display that is or interlaced or process incoming video trough deinterlacer such pattern as you describe will be not visible.

  16. I'm also curious to know if anyone has resolved this particular random ripping issue without resorting to Avisynth post-processing. A simple rip from VOB to MPEG should not (and doesn't usually) require any post work.

    Yet, for reasons I cannot fathom, some random dvds have VOB files that play perfectly normally as ripped VOBs, but turn to mis-interlaced, unwatchable crap when simply ripped losslessly into MPEG via a utility like VOB2MPG. It happens on protected or unprotected discs, with or without AnyDVD decrypter running in the background. I'm speaking here of commercially pressed dvds, although I get similar problems when ripping my dvd recorder discs (always).

    Been using the (ad-free) VOB2MPG v2.5 utility to do these rips for the past couple years under Win 7 64-bit OS. It works fine for 70% of commercial discs but the other 30% (and all of my dvd recorder discs) result in MPEGs infested with the same horrible interlacing screwup shown in Dead Towel's examples. It seems bizarre, because the VOBs themselves do not show the issue, only when they're ripped to MPEG.

    Recently I encountered an additional problem where VOB2MPG could not rip audio from some dvds: the resulting MPEGs had the interlace issue and the audio was pure hash noise. As an alternative, I used MPEG Streamclip to open one of the problem dvds and "Convert To MPEG". To my surprise, it made an MPEG with no interlace error and normal audio. Unfortunately, MPEG Streamclip seems unable to rip an entire dvd at once (it gets hung up on individual "titles" and then you need to go back repeatedly to select the next part, resulting in a multi-part MPEG).

    Anyone know if later versions of VOB2MPG overcome the random interlace and audio glitches? Or can recommend another similar utility?

  17. Never used Avisynth, can someone help me out on how to set it up? Or point me towards a complete beginners guide?

    I kind of gave up tbh, Red Dwarf looked bad in places but it was watchable. But I've just tried season 1 of Futurama and the lines are really distracting.

  18. Been trying to follow a video guide.
    Downloaded Avisynth and VirtualDubMod, ripped a dvd as an AVI. Created a text file and opened it in VirtualDubMod, but I'm getting this error message.

    Avisynth Open Failure:
    AVISource: couldn't locate a decompressor for fourcc MP43

    That will screw up your video even before your AviSynth script. Rip your DVD as a VIDEO_TS folder. Use DgIndex to build an index file of the movie/episode VOB file(s). Use Mpeg2Source("filename.d2v") in your AviSynth script. This way AviSynth will have access to the original MPEG 2 video on the DVD.

    http://www.afterdawn.com/guides/archive/using_dgindex.cfm

    You will need to download the DgMpgDec package to get DgIndex.exe and DgDecode.dll. Put the latter in AviSyth's plugins folder. I recommend you use 32 bit versions of everything, AviSynth, filters, VirtualDub(Mod), etc.

    Rip means copy
    Use a program like dFab , to copy the DVD to your pc as a DVD folder
    Conversion to another format is best done after the copy is made
    To many people use the word rip to mean both processes done at once
    This cause confusion, and in many cases poor quality play files
    As you have found out
    An old pal video old movies etc
    You can try the free program dvdshrink
    Set it to 100% copy size aka no shrinking and DVD folder
    It will copy the disc to the pc hard drive as folder you can then convert to Avi our another format

  22. O.k got a little bit further, used dvdshrink to copy the DVD to my hard drive, then used DGindex to create a .d2v. I also copyed over the DgDecode.dll over to Avisynth plugins folder.

    I load up VirtualDubMod, but now I'm getting this error message.

    Couldn't locate decompressor for format "YV12" (unknown)

  23. DVD Decrypter is old but still works for most DVDs. Some DVDs will require a more up to date program like DVDFab.

    Installing the XviD Codec will get rid of that message. As will installing ffdshow. And you should probably get an up to date Virtual Dub, rather than use VDubMod.

  25. Righto, another little step forward, now it opens the file and I have video! But, no sound.

    Also I tried adding the "AssumeTFF().QTGMC()" to the text file, but I got the error message "There is no function named "QTGMC"".

  26. When you have script problems, show us the complete script. I don't know if you know this or not but QTGMC isn't included in AviSynth - it's a third party add-on. So, you have to get the needed filters and add them to the plugins folder and/or to the script. This page will tell you what you need to get QTGMC going.

    ...now it opens the file and I have video! But, no sound.
    The basic script using MPEG2Source doesn't include the audio. You can add it to the script. but I usually add it back in during encoding or muxing. Have you said what the final format is to be and the encoder you're using? For example, if using VDub there's an audio section where you can add in an external audio file. You will have gotten a separate audio file when making the D2V project file using DGIndex.

  27. You have no audio because Mpeg2Source() doesn't include audio, only video. I just mux the extracted AC3 file with the video when I'm done processing. Or you can open the audio in VirtualDub separately via the Audio menu. Or you can use an AC3 import filter in AviSynth if you want -- Nic's AC3 audio source filter.

    QTGMC() is a third part filter like DgMpgDec. You must download and install it and all the other filters on which it relies.

    http://avisynth.nl/index.php/QTGMC

    I recommend you get "Plugin Package with all Requirements" linked to on that page. And follow all the instructions therein. Yes, it's a pain in the ass getting this set up!

  28. Thanks for the quick reply, I don't have anymore time tonight, but I'll look into the addons for QTGMC and hopefully reply tomorrow.

  29. Sorry for being a bit lax, been fighting a cold and been too tired to play around with this after work.

    Probably should have mentioned something like this at the start.
    My goal is to rip all my DVD's and put them on a hard drive, so that I can watch them through my DVD player. I'm using mp4 at the moment, but my DVD player supports:

    MKV, MP4, MPEG2,
    Xvid,
    JPEG, MPO*,
    AAC, ALAC, DSD,
    FLAC, MP3, WAV,
    WMA
    So yeah, not fussed on the final format, which ever gives the best quality, and hopefully the least hassle.

    I'm going to have a go at installing QTGMC later on tonight.
