Re: What HD format for back ups?

Cyrus,

You will just need to keep in mind for an Archive, you may want to go back to it, so don't hurt yourself by going down to anything too badly compressed. What format - That is where the debate will begin.....if you want to stay as close to uncompressed as possible and something easy to store, consider Sony SR, this will give you mild compression, allow you to make dubs with little degradation and get you away from the data storage if you can't afford to do it.

There are many places that can take a drive of files and spit out an SR tape for you at a reasonable price. SR will be alive for awhile, 10years, can't say but then again you can always redo the transfer process down the road. There will be a generation loss but it will be more than likely insignificant to your needs.

The workflow that a few of our Animation studios are doing is to render the original frames to DPX. Create proxies (which can be everything from DVCproHD to DV25), edit, conform back to the Rave and the original DPX frames, bring into color, color back to the Rave (which creates uncompressed DPXs) and master from there or send frames off to film-out. Of course there are many little steps in between BUT they are all keeping the process completely uncompressed from start to end.

I have even seen some of this going back to LTO for archive, just depends on how quickly you need it when it needs to be recovered.

Hope that helps you a bit.

Cheers,
Ramona
