Frage von videofreak:
Hi Folks,
My oldest dv recordings are now 5 years old.
Now I wonder umzukopieren the earliest recordings, because of the slow demagnetization. My question is:
Does it make any difference whether the objects of a DV camcorder directly transferred to another, or whether you first to the PC via firewire and then captured on a camcorder with dv-in?
Thus, if the material is decompressed at the two options / compressed? So what is preferable?
Some I have already on DVD (as stored dv-avi). Is it reasonable to dub this material back on to dv-tapes (as an additional safeguard, okay, I'm a fuse)-fanatics?
Greeting

Antwort von StefanS:
All "overdubs" via firewire are "theoretically" 1:1 copies. Therefore, it is synonymous in theory no preference whether you of copying or of Camera Camera Camera to PC to Camera.
With the theory I so stresse conscious, because I put a question that I have received no reply so far, namely the error after.
The cameras work with all the fixes that are to a certain amount of error in the position to iron out these errors. But I do not know where the cameras interfere with this error. If it does this only when the analog playout of the tape, it can be errors that are on each tape, with accumulation of the number of copy generations korrekturfähige's talk about the border.
However, if applied synonymous with the digital copy of the error, so each generation should really be a 1:1 copy of what was shown on the first tape to.
But as I said, then no one has responded.
Greeting
Stefan

I wonder if a DVD lasts longer than a DV tape?
Initially there was always the question of a very long lifetime of a DVD. But many think that the DVDs must be stored very well, so they last a long time. And some even say that a disc after 10 years may have already stopped working.
At home, I still have some VHS-C tapes that are already over 12 years and still-with few exceptions, will be playable without quality loss.
Gruss

I wonder if a DVD lasts longer than a DV tape? I type on the DV tape, for that is technologically mature. In the DVD are continuously developing new media for more rapid burner, instead of improving the compatibility and stability of the discs.
But many think that the DVDs must be stored very well, so they last a long time. And some even say that a disc after 10 years may have already stopped working. The DVD is much more sensitive than admit to the Manufacturer. Even the smallest scratch (or fingerprints or dust, or ...?) can make the data unreadable. At a certain error rate is synonymous then the error correction of the DVD player no longer with. The film will be useless.
The apparent this: contrary to the videotape, the tape of the actual enclosed is a housing which can be the DVD page, on which the data is read, directly touching and easy to accidentally damage. With write-once DVD-/ + R provides no protection as in the Cardrigeversion the DVD-RAM ...
