I was not sure if this is the right sub-forum here, but somehow synonymous archiving belongs to PostPro.
Have now been quite a while on the Internet looking for sources, but not really found something. Does anyone of you is perhaps information about how long the shelf life of the Manufacturer warranted different video formats? In particular, the differences between the newer digital formats would be interesting. In the net I can only find information on various computer backup format.
Background: A customer may want to digitize its archive and wonders how long he can wait it yet, or whether to make it at all. We are talking about a wild variety of media. Starting 1 inch of C, on Betacam and BetaSP DigiBeta and up to newer formats such as HDCAM, etc.
I know that the shelf life is much of the storage conditions (humidity, temperature, etc.) and that depends Manufacturer expect in more detail from the ideal situation.
Antwort von Mylenium:
Eventually, the Manufacturer rambled times for Beta SP 4 years, Digibeta for seven years shelf life. If the tapes were stored but already wrong in temperate areas or who have suffered already in production use violent, that's true no more. We have some just 4 years old, digital tapes, which are full of problems and get on analog formats you somehow always fish and spitting, even if they are relatively "young". Manufacturer warranties of getting 'eh. These are only theoretical laboratory values ... So better it is definitely not, if you now want to wait another 20 years ...
Antwort von domain:
A proper backup is based on physical findings, and indeed in the worst possible case and resulted in the end always in digital storage. But, and now comes the important thing: this store has multiple redundant and although s.verschiedenen places exist and must be constantly monitored and subject synonymous optionally including error correction to a permanent process of renewal. This requires an exact timetable exist that must be maintained without exception.

I can play the other day about 35 years old ORWO-tape. No blame and no copy effect! Since then, the GDR in the dune tapes were not able to produce. But I've had at 5 years old BASF Professional Tonbad strong cross talk. 10 years old D-2 video tapes were due to use, because of dust. 10 year old Mini-DV on the other hand perfectly.
