    Hi

    Last week I decided to clean up some of my home movies and author them on to a DVD so they can be played on any DVD player as well as any computer. First step, of course, is to edit the clips as needed and turn them into a suitable format for burning and authoring.

    My equipment is ancient: AMD Athlon CPU, 4gigabytes of RAM, MS XP SP3. Itís slow as molasses, but thatís not a worry to me. I can let this box chug along overnight or for days if necessary and do stuff on my Linux unit.

    So here is my very first effort. I took this clip, filmed with a Canon IXUS 220 HS, and named it Bluetongue_chucks_a_uey_original.MOV

    Code:
    Format                      : MPEG-4
    Format profile              : QuickTime
    Codec ID                    : qt   2007.09 (qt  /CAEP)
    File size                   : 45.7 MiB
    Duration                    : 15 s 82 ms
    Overall bit rate            : 25.4 Mb/s

    and snipped just under 4 seconds off the end using VirtualDub and saved it as Bluetongue_chucks_a_uey_snipped.avi.

    I am happy with what the filter did. Not so happy that the file size has blown out from 36.3 to 951 MiB.

    So, the question is: What do I need to do to reduce the file size without compromising quality and will play on any DVD player?

    Two steps are a waste of time.

    Video-DVD is specified as max 720x576 with ancient MPEG2 codec. You will have to compromise quality to some extent if you insist on authoring DVDs that work on "any DVD player" (actually, with PAL/NTSC differences and whatnot that can't be guaranteed).


    Try AVStoDVD to author the DVD. Since it uses AviSynth it may be easiest to use one of the stabilizing filters for AviSynth and skip the whole VirtualDub process.

  3. Most VirtualDub filters work only in RGB. So incoming video is decompressed and converted to RGB. If you save that without selecting a compression codec you will end up with uncompressed RGB in a very large AVI file. if you want a smaller file select a compression codec. Or frame serve to an encoder that supports frame serving -- that will allow VirtualDub to send the video directly to another program without saving to an intermediate file.
