Backup HVX onto HVR-M10u HDV?

Hi,
I'm wondering if for a cheap backup solution I could acquire on the HVX at 1080i (with it's progressive "look"/gamma/true 16x9) and then transfer (or ideally live stream) to the Sony HVR-M10u VTR? Yes, I know it's HDV but it could solve a lot of potential problems or help backup material in an affordable way.
The M10u has Firewire in, a 3.5" 16x9 LCD, is battery operable in the field (Sony L series). My thinking in this is that is you shoot in 1080P it goes to tape at 1080i regardless, which the M10u deck records in (either 50/60i). You would get all the advantage of the "look" of the Panasonic, but for jobs that don't require keying/4:2:2 but more importantly longer record times this may be a great solution.
Just a thought as I was using an M10 on set the other day and it's a real handy device.
Just a thought I'd pass on. For those that have used HDV extensively (as I have) it's actually surprisingly good...if you treat it right with your camerawork. Despite there being so many negative comments on these boards...those of us who have actually used HDV and seen what it's capable of (in the right hands) it would be a viable tape backup solution if it will accept the firewire at 1080!?
Hope people find this suggestion useful...and any comments are appreciated.

If that works, it would be a very handy idea, but wouldn't you have to take an analogue output from the camera. I presume the firewire would only output the HVX's codecs, ie not HDV.
 
HDV is not the devil. If ya know how to work around the limitations, the same way we do with MiniDV, it's very good. Truth is MPEG2 is substantially more efficient than JPEG's. All the hullaballoo about HDV motion artifacts is certainly blown out of proportion at times. In the same way we're mindful of panning speeds in 24P, nearly anyone here could make HDV work out very well. My only nitpick for the format stems from lack of 24P in an all-in-one form factor camera body (dvx, pd170, z1, etc.).

For as much as an HDV deck costs compared to a laptop computer, I would prefer the laptop as at least it *could* be battery operated if necessary. I don't see any particular advantage of going to tape myself. I believe the firewire interfaces would not be compatible which leaves "only" the analog component connectors... I already have a laptop with FCP which directly influences my opinion of VTR v. Laptop, of course.

Hope this helps.
 
Won't work. The Sony deck has no HD input other than HDV. The firewire input will only work if you're already sending it an HDV signal. And it doesn't have HD analog component input. So there's no way to get a high-def signal to the deck.

Unless you got some sort of analog-component-to-HDV converter box and stuck that inbetween...

Laptop computer would be a much better solution. You could record the native DVCPRO-HD signal, you could monitor it, you could get much more storage in a continuous recording, plus -- heck, you'd have a laptop! And you could get a killer, killer, killer laptop for half the price of the HDV deck.
 
Point taken Barry,
I now realize what you are saying by firewire IN stream has to be HDV.
I think people misunderstood me...a laptop still has the problem of how to affordably backup HD to a consumer/viewable medium on location...or for long form projects.
An HDV tape at $3 (std mini-dv tape) to $15.00 (for Digital Master) is a simple way to give your clients "HD" for backup or viewing purposes. It seems practical, as it's realtime. I'm a big fan of backing up on location. It would help appease all those old school clients who want tapes.
A number of local production companies and shows (such as Battlestar Galactica) are using HDV decks as part of the production chain. I assume with the single chip HDV cameras (coming) there will me more and more HDV capable playback units out there.
It was just a thought...too bad the firewire streams are incompatible.
FWIW

You are assuming all your clients are going to already own the Sony HVR-M10u deck to playback these backup tapes........
