This is all true, but as far as I saw, the original footage was DV
quality at best. I heard no mention of BetaSP, D1, or D2 footage in its
source state. Since that is the case, there is nothing at all lost by
storing footage in DV format, and a lot of space gained. DV is in fact
compressed at 5:1, using discreet frame constant bit-rate compression.
It makes it an excellent choice for future editing for video or web use.
There is also a product on the market, I believe the name is CatDV
(shareware) which will catalog DV tapes, and allow indexing, keywording,
search and retrieval of footage. This makes it practical to use actual
DV tape as the storage medium, and then use automated machine control
for retrieval and digitization of content required for a specific
project. The purpose here is that DV tape is a fraction of the cost of
hard disk space as well as maintenance free. Because of the frame
accurate machine control, DV can be considered a digital archiving
