Simple Archiving to Blu-Ray?

[Sergei Franklin]

Once this company https://www.millenniata.com has a blu-ray version we might have a archival option for digital media.
I just bought a 12x Pioneer burner. Can’t find any info on how long standard BD-R discs last.

I’ve read somewhere that BD disks are touchy. Much more than DVD’s. So must be handled very carefully. But that said, they should last long enough for genuine needs, and if the media is all that valuable, you make extra copies of course. Problem I see with them is time it takes to burn them, and read from them, and cost per gig. I suppose the price is falling on them though. LTO technology is improving fast on the cost per gig thing, and the speeds are a lot faster than Blu-Ray. Have to get them suitable for media files is all.

Hi,
I have to archive 49 one-hour HDV tapes.
Over the last year, we videotaped the construction of the Walkway Over the Hudson and the client simply wants a backup of the tapes for use as long as possible (years) for several different historical uses.
I don’t have the original captured tapes done for the project, just the tapes themselves.
What is the cheapest and most efficient way to do it?

Thanks,

Michael G

Dub them via FireWire camera to camera or deck to camera or deck to tape.

Thanks Jerry,

However, I understand thru the Cow that DV tape is only physically good for 5 to 10 years and LTO tape will hold together for 50.
This is the first job we’ve done that requires a very long term archive of all the source material, since it documents the construction of the Walkway Over the Hudson which is now a state park and the people will treat this video as an historical resource.
I’m afraid I may have to capture the 49 hours of HDV tape to a hard drive after all, and then put the stuff on LTO tape. I was trying to avoid that.
Another caveat: I hear some bad things about LTO tape also.

Oh well,

I’ve not used LTO, but have used DLTs without a problem. I didn’t have to archive that long however.

That said, I just taught an FCP class to a group of DP’s this past weekend who would know much about this issue, and they’ve looked into this for the Academy of Motion Picture Arts. Apparently, banks have been using LTO for a while now to back up all of the account information. Well… the oxide seems to not be lasting that long, in fact the DP that I had this conversation with said that banks are reporting loss of data. Not all the data, just some of it only after about 3 years… pretty scary if you ask me. The manufacturers often “exaggerate” shall we say. The DP’s have come to the conclusion, that even if you’ve shot digital (aka RED or other digital camera) that the safest thing out there is to PRINT the film… it lasts a lot longer. But that doesn’t cover all the out takes etc, just the film itself.

There isn’t an easy answer to this other than if you were to dub to tape, you then have to redub it every so often. I’ve been using pro tape whenever I’m using tape and it’s metal. It lasts a TON longer than the cheap stuff. I have betacam tapes that are at least 15 years old that work OK.

I’d still dub it through firewire so it’s a perfect clone, and then in about 10 years do it again until there’s a really rock solid backup. Glass is in development for this actually.

Use the Pro tape… not the cheapie stuff. Sony makes it, and it costs about 18 bucks per tape as I recall. It’s the pro version of HDV tape.
