AVI to VCD\DVD & compression

Discussion in 'Amateur Video Production' started by Susan Clayton, Dec 2, 2003.

  1. Hi,

    I have got a load of animation clips here in various formats (avi, mpeg,
    divx etc.) that I want to make into one VCD and then onto a DVD.

    Taking one step at a time, VCD comes first due to the fact that as yet I
    haven't got a DVD burner.

    What I am doing is converting all clips to uncompressed avi at 352 X 288 for
    PAL VCD. I am using a mix of CucuSoft AVI to VCD converter, TMPGenc,
    VirtualDub and Premiere. As I convert more, my hard drive space is rapidly
    diminishing so I am wondering what sort of compression I could use and that
    would be entirely compatible with VCD\DVD conversion.

    I hope the above makes it clear and I thank you for any help or pointers as
    I feel somehow that I may be approaching this the long way around.

    Thanks

    S

    VCD is a very specific format. You can use TMPGEnc's project wizard
    to convert your uncompressed AVI files to PAL VCD format. If you
    later want to move these VCD files to DVD, the VCD video format will
    be compatible, but the audio will need to be resampled at 48KHz.

  3. Roxio Toast 6 (macintosh UNIX) does MPEG1-DVDs now. It is possible to not
    have to demux and resample to make a workable DVD disc.
    It seems to be a matter of someone writing the software.
    I want a MPEG1-DVD capable program for WIN98SE.
    Demand creats supply.

    I think it still has to be done, but the software can do it
    automatically.
    Ulead DVD Movie Factory 2 will convert the audio from a VCD MPEG file
    automatically.

    That's not hard.

    Take your source A/V file and render them to elementary video/audio streams
    as follows. The following assumes NTSC:

    Render the video to 1.856Mb/s CBR MPEG-1 at 352x240 resolution with 29.97i.
    Sony's Vegas+DVD does this as does TMPGEnc.

    Render the audio to 192Kb/s Dolby Digital (AC-3). Once again, Sony's
    Vegas+DVD does this nicely.

    Import them into your DVD authoring program (e.g., Sonic's ReelDVD) and
    create/burn your MPEG-1 DVD-Video.

  6. What about already-made "white book" MPEG-1? Demux (split the assembled
    finished stream) and redo the sound, realign the sound to video, . .
    ..?????
    Do people have so much frivolous time to waste. You can't make the
    original sound or video better than it started, so it's wasted time to
    convert it any way at all.
    It's the task of the set-top player to read the disc and give us back our
    stored memory. Software that can make a VCD can make a DVD filled w/ the
    same type file.
    Roxio advertises (in MacWorld Ded 03) that the preexisting stream is used
    in the MPEG1-DVD. This is UNIX compatible.
    Surely some enterprising DVD software maker will create this needed
    product.
    Just like some set-top DVD maker will give us a mouse-pad and
    cursor/slider or jog-dial for disc playback random entry point - just to
    save time on the menu creation.

    That's easy, just as spelled out here:

    You assume we are starting with VCD source material or crap quality source.
    Some people want to take great quality source material, say DV25, and burn
    it onto MPEG-1 DVD-Video. Reasons being is you can fit a lot more minutes
    on a single DVD-R in MPEG-1 video/AC-3 audio at decent quality than in
    MPEG-2 video/AC-3 audio. And the quality is better than VCD because you
    can encode to 1.856Mb/s MPEG-1 video rather than the 1.150Mb/s limit of VCD
    proper.

    Taking VCDs and putting them onto DVD-Rs as listed in the above DOOM9 guide
    is not interesting.
