Rendering with vegas 5.0 for DVD Architect 2.0

Discussion in 'Amateur Video Production' started by Kiriakos Georgiou, May 17, 2004.

  1. Hello, from a DV newbie. I am learning enough to be dangerous but I
    am a newbie nevertheless.

    I have my home theater hooked up to my PC via a Canopus ADVC-100 (plus
    a digital coaxial for sound output to the home theater) and I use
    Vegas 5.0 for video capture/editing along with Sound Forge 7.0 for
    non-trivial sound editing and DVD Architect 2.0 for burning onto DVDs
    (CD Architect 5.0 for CDs).

    To be honest I haven't burned a single DVD yet - only one SVCD (which
    looked darn good when I played it).

    Right now I capture from firewire to DV. I do elementary editing such
    as trimming, transitions, etc, then when I am done I render to NTSC
    DVD mpeg, with the idea that I can watch it on my computer, later burn
    it on DVD if I want, or even play it with Vegas via firewire and the
    ADVC-100 to my TV.

    Now I discovered that DVD Architect (DVD-A) will recompress/transcode
    the source before burning onto a DVD unless the source was rendered
    with the DVD-A Vegas mpeg video-only template. I am not sure I
    understand this - if I am going to separate video and audio in Vegas,
    how am I going to sync them back in DVD-A? Can it do this like I do
    with Vegas? and of course now I lost the convenience of playing video
    and audio on the PC with just a double click :)

    I am interested in learning to do this the 'right way' so I can store
    finished clips in some kind of compressed format that can be viewed on
    the pc and be reimported in Vegas or DVD-A for future projects.

    Is it common practice to store clips that might be used in the future
    in DV (avi)? Also, is it common to just use DV in DVD-A - for a
    newbie like me it's simple and I imagine since there is (almost) no
    compression there should be no quality problem as there is from
    rendering mpeg back to mpeg (yikes!)

    Is there a commonly accepted 'bible' book that explains the workflow
    and processes without assuming expert knowledge of the video/audio
    field.

    regards,
    Kiriakos

    If the seperate audio/video streams were rendered off of the Vegas v5.0
    timeline the same way, they should be in perfect sync when those two
    elementary streams are imported into your DVD authoring program.

    The right way is very subjective, but this is the right way for me:

    I create ISO image files of DVD-Videos with my authoring program and use
    DaemonTools along with Media Player Classic to mount/view them on my PC.

    This way doesn't easily allow you to reimport the content into Vegas/DVDA
    for future projects. If I want/think I may be using something in future
    projects then I will store them as you allude to in the below question
    (i.e., DV25) since I, like you, use a Canopus ADVC-100 or DV from a miniDV
    camcorder for nearly all of my source footage.

    Most people don't want to reimport finished clips that have been
    compressed beyond the original source material because of quality loss
    from multiple decode/renders.
    I'm not sure here. I thought DVDA v1.0 was garbage, so I never used it.
    DVDA v2.0 looks like quite an improvement, but I haven't gotten around to
    reading the manual and figuring it out.

    I've always used Vegas for my editing, for my rendering of the audio to
    Dolby Digital (AC-3) format, and sometimes for the rendering of the video
    to DVD-Video compliant MPEG-2. Now that Vegas v5.0 has added two-pass VBR
    MPEG-2 encoding, I'm hoping I'll have less need for Canopus' Procoder
    since the convenience of rendering from the timeline with Vegas is nice
    versus rendering to intermediate DV25 AVI files (Debugmode's Vegas
    frameserver never worked well/was slow for me).
    I've usually found the manuals for my DVD-authoring programs to explain
    the workflow and process in a fairly straightforward manner.

    Actually, DVD-A 2.0 is supposed to handle a few formats, such as
    elementary streams, which is kind of the standard for DVD building, in
    addition to the special video-only program stream is used in 1.0.
    How are you going to de-sync them? If they're synced in Vegas, there's
    no mechanism to lose that sync, unless you're editing one
    independently of the other.

    For historical reasons I suppose, it's standard practice to feed DVD
    programs separate audio and video assets. Some of the very consumery
    apps probably take an MPEG-2 program stream these days, but most
    serious apps don't. Neither does DVD-A (not quite a serious app,
    though I haven't bought 2.0 yet, though soon...).
    I wouldn't do that.
    Yes, I would keep any and all editable bits in their original, dry
    formats as much as possible. DV itself is compressed; any additional
    compression is inherently come kind of compromise. There's no good
    reason to compound that by re-rendering a re-rendered clip. MPEG-2
    certainly takes up less space, and sure, you can edit it just dandy in
    Vegas (though not without loss, while DV is far more intelligently
    handled, so you only re-render that which changes, not practical for
    frame-accurate MPEG-2 editing).
    Not sure what you mean there. DV will be rendered to MPEG-2 in DVD-A,
    just as any other non-MPEG video asset would be. There's no real
    problem with having DVD-A do the rendering, but I always do it in
    Vegas. While they both use the same MainConcept MPEG-2 engine, you
    have more control in Vegas, and also the luxery of things like
    exporting markers in Vegas to form chapter points in DVD-A. If you're
    editing full featured DVDs, that's a nice time saver.
    Honestly, given the price of Vegas + DVD, I don't think anyone's
    expecting novices to pick it up. That may be an incorrect assumption,
    but that seems pretty typical of this level of software.
