Video -- digital archiving

The ideal way, one that is working today, is to digitize at D2 quality.
Have a hybrid automated online tape library combined with an online HDD
raid jukebox.  Encode in hardware on the front end and decode/transcode
in software on the backend.  If this is a funded project, the
methodologies are readily availale.

Hello Sivakatirswami,

in my job I deal a lot with digital Video (hundrets of hours of
videofootage) I edit with final cut, (importing DV Streams directly from
tape). These streams are compressed by a hardware component (in my case
a digital cam) in a 5:1 ratio, when playing back to the cam it
decompresses the material and sends it to a tv-set. When I need the
material for use on computers I create mpeg1 files (and am just giving
Mpeg4 a try, wich implemented in QT6 seems promissing) I store the
videofootage (DV) on tape, save my Projekt settings, and all other
relevant data to a CD-R. Storing uncompressed video to the HD is only
possible, if you have a videocard and the software you need to grab it
directly. In Quicktime you would have to set the codec to none. If you
grab via Firewire, you need to use the DV codec. 
Storing an uncompressed file, created from your DV-footage,would
incredebly increase the amount of data you have to deal with, but the
quality would only improve slightly. And it would take hours of
rendering time. I guess storage on tape is the cheapest way, even though
storage of the footage on external HDs would be more enjoyable. (Using a
firewire bridge and buying a harddisc for each project for fast changes
on it, leaving the tapes as backups. Have a nice day.
