  1. Hi,

    I've got an MPEG-1 file (352 x 240) 1150kbps 29.97 fps that I want to convert so I can put it on a PAL DVD.

    I could just import it into a all-in-one program, but from experience this gives poor results.

    I've converted NTSC avi files before (xvid/divx) using virtual dub / besweet etc but as this is an MPEG and my version of virtual dub only deals in avi i'm stuck.

    Also the audio in the MPEG-1 files is 44khz is this going to be an issue as I know DVD is 48khz?

    Could anyone point me in the right direction? I've looked for guides on this but haven't found one, hence this post.


    Thanks

  2. VirtualDub can read MPEG 1 files. VirtualDubMPEG2 and VirtualDubMod can read MPEG 2 files. You'll have to convert the audio to 48 KHz sampling too.

    The technique you've probably used before, speeding the frame rate up from 23.976 fps to 25 fps, won't work with a 29.97 fps MPEG 1 file. (Well, it will work but the change is speed will be very noticeable.) If the file came from a 23.976 fps source that was telecined it has either been drop-field or blend deinterlaced.

    If it is drop-field deinterlaced you will see that one frame is repeated every four frames, ie, 1-2-3-4-4-5-6-7-8-8... You can try using AVISynth and the Decimate filter to remove the extra frames. That will leave you with 23.976 fps. You can then speed that up to 25 fps, adjust the audio speed, etc.

    If it is blend deinterlaced you'll probably end up reducing the frame rate from 29.97 fps to 25 fps by throwing away every 6th frame.

  3. Sorry, should've made myself a bit clearer.

    I can open the MPEG in virtual dub and change the frame rate but the only option I have is to save as AVI which throws up an error.

    If I was you, I'd keep it NTSC. Just author it as NTSC DVD with TDA. Most PAL players do NTSC DVD fine. Much too much trouble doing a TV system conversion IMO.

  5. .....I'm tempted to do as you suggest and just author an NTSC DVD however I'm converting the file for a friend who has specifically asked for PAL conversion.

    Is there a way to do it?

  6. Frameserve from VirtualDUb to your MPEG encoder.

  7. hmmm that sounds complicated

    Are there any guides on it?

    ...which would mean you have to resize and reencode too - lowering a low quality vid even further. If you up the bitrate to say 4000 kbps and encode to 352x288 mpeg2 it may be not that dramatic.
    Guides for frameserving with VirtualDub left.
    Even better - use AviSynth.

    You know that you can use MPEG1 video on a DVD. I've made a bunch of DVDs using mpeg1 files. Demux, convert the audio to MP2 at 48k (Besweet), author. Even if you have other titles on the same DVD that are PAL, this works (on my player, which isn't anything special).

    This is very fast and you don't lose any quality, as you inevitably will in any format conversion.

    Some authoring apps may baulk at the video files, I use GuiforDVDAuthor which isn't fussy.
    SVCD2DVDMPG is a free app that does the demux and audio conversion and sets some flags in the video to keep authoring apps happy.

    Yeah. I tend to think that making a disk that plays is the ultimate aim, and he just assumed it needed to be PAL. If the mpeg1 works, he's got better quality with less work. If it doesn't, he's out the cost of blank. Either way he learns something.

    I agree, better keep it NTSC, but that doesn't seem to be an option in this case.

  13. OK, I've created the DVD as an NTSC dvd with PCM sound, no probs there, however:

    It works fine on my new Pioneer DVD player (2005), doesn't work at all on my older pioneer player (2000) comes up with 'Disc Not Supported' and it doesn't work in my new panasonic DVD recorder either (2004) comes up as 'Disc not supported'. Works fine in a PC.

    All 3 players and TV's are definately NTSC compliant, so why does it onoy work on one of them? Is it the resolution?

    I created an ISO from TMPGEnc DVD Author Pro and burnt with Neo which said 'burning CD-ROM MODE 2' funnily enough, is this the reason, is it reading it as a VCD ?

    This is primarily why I wanted to create a PAL disc in the first place you see as I know they definately work on my players and other players.

    Any thoughts?

  14. Mode 2 is proper for VCD.

    VCD is not a part of the DVD spec. Many DVD players won't play VCD, especially SVCD.

  15. Ok, so back to my original question.

    How do I convert this NTSC VCD format video file to a dvd player friendly version preferably Pal??

    That does sound like it's the problem.
    Some apps just go ahead and decide they know better than you.

    For what it's worth I use GuiforDVDAuthor to author disks, it doesn't reencode my files or decide it's really a VCD, it just does what I tell it to.

    I recall there is a method to patch the video to trick stubborn authoring apps.
    If you want to try this get SVCD2DVDMPG, the free version. It takes an MPEG1, patches the video and converts the sound to 48k sample, giving you DVD compliant files.

    Thanks for your help.

    The audio in the said DVD is definately 48Khz, TMPGEnc wont let me author to VOB files without a 48Khz audio stream, plus the DVD player it does work on sayd 48/16 PCM for audio stream.

    Similarly the video stream seems fine, standard NTSC VCD

    I guess TMPGEnc is reading that and deciding you really want to author a VCD.

    See http://www.svcd2dvd.com/Help/GettingStarted.aspx
    Has some notes about changing headers, perhaps that is the trick.

    Or you could try another authoring app.
    Try ReJig, it's free, very small and fast, but no DVD menus.

    Didn't even know TDA authored VCD (I'm so bold I'd say it doesn't!) - And surely PCM audio isn't VCD standard (or even allowed).
    Try to burn directly with TDA - There's something fishy going on here. Also, let TDA encode your audio to mp2 - I think it can.
