An example of why converting AVCHD to HDV for editing is a BAD IDEA !

  2. Who ever said that converting from one heavily compressed format to
    another heavily compressed format, is such a good idea :)
    Using intermediate codecs (ProRes, DNxHD etc) works fine.

    By the way, I don't get your reference to "converting to HDV", but
    then I am clueless as to what Voltaic is.

    One of the suggestions offered here in a prior thread to "solve" the
    relatively stressful demand of AVCHD editing was to convert first to
    HDV, which was offered in the same post as a supposedly superior format
    to AVCHD.

    Programs like Voltaic for the Mac and Vasst Upshift for the PC do
    exactly that. They are merely AVCHD to HDV converters.

    My post last month was merely to show one dissatisfied user's outcome
    when using this method. As you say Martin, converting / recompressing
    one highly compressed format into another is a very bad idea.

    The same logic holds true in the opposite direction for taking HDV
    footage and then authoring AVCHD disks or AVC BluRay disks, both of
    which clearly show the visual penalties for making such conversions.

    BTW, The Voltaic software is described at:

    decent like Cineform's Neoscene, which keeps the material intact.

    Thanks for the link to the Voltaic site.
