    we have several hours of home video on a hard drive. as .avi files,
    which is how they transfer, they take about 13.5G per hour.

    we want to put this unedited footage onto dvds (preferably viewable,
    rather than just data) primarily for storage. eventually, we'll want
    to put the material back onto the computer so that we can edit it.
    when we do that, we don't want to lose quality.

    we successfully took an .avi from one tape (13.5G) and used myDVD to
    burn a dvd (3.75G) that seems to look great, be good quality, etc. so
    that seems to be the easy answer.

    my concern is that when we later rip that dvd back to the hard drive
    for editing purposes, we're going to lose quality.


    1. would we lose quality by doing that? [13.5G avi -> 3.75G dvd ->
    ..avi (or other format)]

    2. what's the best way to store the data on discs but still be able to
    get it back on the machine for editing later with minimal quality

    sorry for the awkward phrasing ... i'm new at this and a lot of the
    technical side is a bit beyond me, but i'm learning.

    thanks for the help.

    DVD compliant MPEG-2 is not a great idea.

    You could store the raw files to DVD by using an archiving program,
    but you would not be able to view them without dumping them back
    to the computer. This option would give you no further loss though,
    but it may take too many DVDs, depending on how many hours
    you want to archive.

    You could also use a tape back-up (DLT?) but I had very poor experiances
    with tape archives in the past, and gave up on that approach. It could be that
    the equipment has gotten much more reliable than it once was.

    You could also drop them all on a timeline(s) and dump to DV, or D8,
    tape and maintain much more of your original quality than DVD a
    complient MPEG-2 could. The DV tapes would be viewable.

    You could also just store them on a hard drive. I do that a lot. Drives
    are so cheap these days, that it just doesn't pay for me to go through
    the hassel of backing the stuff up. I use removable drive sleds for the

    While we're on the subject.
    I've ask before with no response.

    Anyone know why I'm getting artifacts by
    sending unedited DV back to my camcorder?

    I want to archive back to tape.

    I'm guessing it has something to do with
    the camcorder creating 'frames' from the
    input. Make sense?

    Thanks for any ideas.
