  1. Hello,

    I am attempting to change an interlaced PAL DVD to NTSC DVD

    I am trying to do something similiar to what Noahtuck is doing https://www.videohelp.com/forum/viewtopic.php?t=263172


    Steps taken:

    1. Rip the PAL DVD files onto the Hard drive using dvd shrink...or DVDDecryptor in file mode
    2. Use dVDindex to demux...ie File --> save project and demux video...which in my case creates ( test2.demuxed.m2v)
    3. Load the (test2.demuxed.m2v) video file into TMPGenc pLUS.
    load the dvd (NTSC).mcf template
    load the unlock.mcf template
    In the videos tab in MPEG Setting
    change framerate to: 25
    Motion search precision: Normal
    In Advanced tab
    check Deinterlace(Even field (adaptations))
    check Do not frame rate conversion.

    The stream type will be ES (video only)
    Press start and the encoding begins for the pal to ntsc. (So I thought)





    4. I then use Tmpgenc author to do the authoring and the final result is a ntsc compliant dvd with no audio sync problems...

    How come DVDindex still saw the m2v (test2.demuxed.m2v) (that was encoded with tmpenc plus) file as interlaced and not progressive?

    Should I even bother using the Deinterlace filter (even field (adaptations))
    in the TMpgenc plus? Does this option change the video to progressive or is there some other way to change it to progressive using tmpgenc plus?

    If i should keep using the Deinterlace filter in tmpgenc plus; is it a good idea to use even field (adaptations)?

    Was the dvdindex wrong about reporting my m2v file as being interlaced?

    Was it really progressive? If not then how was i able to still convert this file from 25-->29.97 with dgpulldown

    I thought DGpulldown can only convert progressive video and not interlaced?

    Any help, comments will be very very appreciated.

  2. Ok It seems that no one knows the answers to my questions.

    Does someone here know about the deinterlace filter in TMPenc plus?
    Checking this filter option will turn an interlace video to progressive right?
    Should i have left the deinterlace filter as the default which is none? Or was choosing the even field (adaptations)) option a good idea?

    Anyone?

  4. Hi-

    I am attempting to change an interlaced PAL DVD to NTSC DVD

    And how do you know it's interlaced? Just from what DGIndex told you? That means nothing. It's only telling you how it was encoded. You have to look at the frames themselves to see for yourself if there's any combing/feathering/interlacing. There are very few interlaced PAL DVDs, but the vast majority are encoded as interlaced. There's a big difference.

    The reason that DGPulldown creates a progressive .m2v is because it assumes that the source is progressive and sets the -prog_frames p flag , as you can't run pulldown on a truly interlaced source. If your DVD really is interlaced (which I doubt), you'll either have to deinterlace it in advance, or use another method (like one of Xesdeeni's AviSynth scripts) to convert it to NTSC.

    Should I even bother using the Deinterlace filter (even field (adaptations))

    Not unless you've determined it's really interlaced. Deinterlacing a progressive stream will wreck it.

    Was the dvdindex wrong about reporting my m2v file as being interlaced?

    No, it only reported how it was encoded, not if it was really interlaced.

    I thought DGpulldown can only convert progressive video and not interlaced?

    You shouldn't use it unless the stream really is progressive. It's giving you credit for knowing what you're doing. A mistake, perhaps, in this case.

    I don't know anything about TMPGEnc, but you may have accidently done it all correctly, if the DVD turned out OK. It plays OK in your DVD player? The audio is in synch?

  5. Hi manono,

    Thanks for you response,

    Well I am pretty sure that the pal dvd is interlaced. I looked at it closley using VirtualDubMod.

    I read this thread https://www.videohelp.com/forum/viewtopic.php?p=1282459&highlight=progressive+interlaced#1282459 and saw that my video had "distinct overlapping images".

    I don't know anything about TMPGEnc, but you may have accidently done it all correctly, if the DVD turned out OK. It plays OK in your DVD player? The audio is in synch?

    Yes the audio is in synch, I played the final result on my computer using powerdvd. However, I haven't burned it yet on a DVD and so have yet to play it on the DVD player. On my computer the picture looks fine so I guess i may have accidently done it all correctly...

    I will burn it on the dvd when i get the chance and see how it looks...

    Also if anyone here has ever used deinterlaced filter on tmpgenc plus; please answer my questions regarding it from the my post above...

    thank you..

  6. Hi-

    I went and saw that anime picture in that thread to which you linked. Yes, that's what interlacing looks like. A pretty good example, actually. Theres always a good chance it just has the common PAL "shifted fields" and is really progressive. The way to check that is to put Telecide(Order=1,Post=0) in an AviSynth script and see if it makes it "clean" again. You can test to see if that fixes it by opening the AviSynth script file in VDubMod before encoding. Most people around here seems to prefer feeding their video directly into TMPGEnc, or frameserving with a VFAPI, for reasons which escape me. You'll get much better results (and much faster results) if you learn AviSynth and use CCE for encoding for DVD. But even AviSynth together with TMPGEnc is a better combo.

    Only deinterlace as a last resort. I assume that TMPGEnc's even field (adaptations) interpolates off of the chosen field. If so, you lose half your resolution. If I'm correct in that, then AviSynth has much better deinterlacers available, such as TDeint or KernelDeint.

  7. hi,

    I am not familiar with AviSynth. How do I create this script that you are talking about.

    Also have you ever heard of DVDsanta; i heard it converts a pal dvd to ntsc dvd. Would you recommend using that instead because this interlaced, progressive issue is giving me a headache....

  8. LoadPlugin("C:\Path\To\DGDecode.dll")
    LoadPlugin("C:\Path\To\Decomb.dll")
    mpeg2source("C:\Path\To\Movie.d2v")
    Telecide(Order=1,Post=0)

    There's the basic sample script. First you install AviSynth if you don't already have it. Then you get DGIndex. And finally you get the Decomb filter (which includes Telecide and some other things). I think these will be linked automatically when you read this. DGIndex includes the necessary DGDecode.dll. You stick the DGDecode.dll and the Decomb.dll somewhere. You open DGindex and then open the Movie Vobs in it and save a Movie.d2v Project File (File->Save Project). Make sure you have your paths correct, and then open the Movie.avs (the AviSynth script file, which can be opened in Notepad) in VDubMod, and scroll around to see if the movie is no longer interlaced. If that didn't help to make it look progressive again, then you're back to Plan B, or C. Those might be deinterlacing it before encoding (I'd recommend TDeint (better but slower), or KernelDeint (faster and almost as good) if you continue with AviSynth, or one of the TMPGEnc deinterlacers if you prefer the way you're already familiar with. Or do it the Xesdeeni way, keeping it interlaced (he also requires the use of AviSynth).

    The docs included in the DGDecode package are quite good at explaining things, and at http://www.avisynth.org you'll find a wealth of information for getting started with AviSynth. There's a learning curve, but once you learn a bit of it, you won't go back.

    I've only read about DVDSanta, and never used it. But from what I've read, no one in his right mind would use it. But I'm sure I'd get an argument about that opinion from the good folks around here.

    Edit: Links to 2 of them showed up. You can get Decomb here:
