    Do you know why importing a mini DV tape (recorded on LP) would take up so many gigabytes? I'm trying to take a 60 minute recording of our play and make it into a dvd, but it is like 12 gigs when imported into iMovie (too much for 1 dvd).

    Any ideas?

    Should I compress the imported footage, and if so, how?

    Thanks,
    Kevin

    Don't worry, it will all be fine in the end, though you will use more disc space in the interim.

    The DV compression format takes about 250MB /minute (4 min/GB). DVD's, however, use MPEG2 compression, which produces a much smaller file size, though it is arguably also less editable. This is fine for DVDs as it is a delivery system, not an editing platform.

    When you finish editing your video and transfer it to iDVD to burn to a disc, it will be transcoded to MPEG2, and you will be able to fit your 1 hour video comfortably on a single DVD -R disc.
