Well about 75% of the library was thrown out over the years, because
no space was available for storage, and nobody wanted or had the time
to preserve them before they were chucked, until I came along. There
were minimal archives done over the years, but the majority of them
were done on VHS tape, in EP quality at that. Very surprised at how
they held up, but still EP quality.
I dont believe that this would be interesting enough for a historical
society, but who knows. Most of the shows left are instructional shows
such as cooking, crafts, local sports coverage, current affairs, etc,
of local cable budget quality. Maybe worth it to people locally, but
probably worth more to the volunteers/staff, or use for archival
clips.
As stated before, do not know if these will every be re-broadcast, but
the ability is a must. Obviously there is probably not much that can
be done with the VHS tapes, but more concerned about the Umatics. I
have acquired the tapes and they are stored in my apartment, so i dont
have a lot of space to store them.
I have so far come to the conclusion that since DV is better than
Umatic, i will record the tapes into the imac and save them as dv.
Also, the input i have is a firewire canopus advc-300 converter.
Thanks everyone for all help thus far.
