Turning DV avi clips to emailable movie clips

    Im looking for the best combination of turning say a 15 minute avi DV clip
    into a highly compressed, emailable file. Im hoping that making the size
    smaller, reducing the colour depth, and compression will allow this?
    If a 20 minute DV avi is about 4.5Gb, and the DVD mpg2 encoded version is
    about 1Gb (estimate with my VBR encoding), can a wmv for example be taken
    down to 15 to 20Mb and be ok?

    Yes. But using formats such as Divx can make a much better quality
    compressed movie. The only problem is that whoever you are sending it to
    must have a codec installed to read the file.

    It is better if you know the person because there are muc

    15-20MB is still not emailable without being chopped up into much
    smaller chunks.

    I don't do windoze so cannot comment on the WMV compression

    You can however use one of the many MPEG4 codecs to compress further
    than mpeg2

    I get around 60 minutes of DVD quality video down to about 1GB using
    ffmpegs MPEG4 codec

    if you don't need the quality, try reducing the bit rate, resolution and
    as a last resort frame rate

    You should understand that wmv, avi, and mpg are video file formats,
    not compression types. Within any of those file types you can use
    different compression types (although mpg files almost always use
    mpeg-1 or mpeg-2 compression). I would avoid wmv format because it's a
    proprietary Microsoft format which is not well supported by other
    software.

    As for the best compression type to use, DIVX is a open variant of
    mpeg-4 which produces pretty good compression and quality, but you
    have to install a DIVX codec to play it (free download). Mpeg-2 is
    more universal, in that almost everyone already has the mpeg-2 codec
    on their system.

    It is going to be hard to email anything over 4.9mb through most email systems.
    So....most ISP's give you 10 to 20mb of free webspace. Thus, I would render the
    large movie down to 320 x 240 and 15 fps using Microsoft movie maker or what
    ever your using. Just shoot for around 1mb per minute when using WMV's and you
    should have a decent compressed, viewable file to get your point accross. If
    its really important the material look like DV quality, then burn to CD and
    forget email/web quality.
