Andromeda HVX?

Hello,

Just figured I'd chime in.

The current Andromeda+DVX system produces significantly more dynamic range than the HVX currently produces via DVCPROHD. It also allows the user to control color in the native 12-bit RGB colorspace, into an uncompressed output free of compression artifacts. It also allows recording at more than 8-bits color in full bandwidth RGB.

It's understandable to assume that because one camera came after the other, that the new one is superior in every aspect, but the truth in this case is a bit more complex than that. Andromeda uses only the data from the sensors and ignores the rest of the electronics which are the bulk of the camera. The HVX and DVX are actually fairly similar in how they aquire the image, the main differences being the native 16:9 ratio and the 60P capability of the sensors.

As Jared pointed out, these are different tools. We have plenty of users who own both our system and an HVX, and use them for different shooting situations.

Cheers!

Juan and his crew at Andromeda have stated they have a suprise coming to NAB and my guess is that it's the modification for the HVX. 4;4;4 on the HVX would be a modification that I would very much consider buying into.
 
Why, when you've got an HVX? Wouldn't you rather have 1920x1080 @ 4:2:2 in variable frame rates? That's what the Andromeda HVX could do...
 
It was something like having a different kind of "film stock". Especially now since we're about to put the thing through extraneous usage in the next few months. FINALLY.

I think the Andromeda will offer a different kind of HVX look as well, as opposed to ones that we can all point out in a crowd o'footage.
 
Maybe. Andromeda footage takes a DVX to being as sharp as any of the low-cost HD cams, so starting from an HVX should mean being able to get even better, no?
 
Well maybe barry, but thikn of it liek this, the DVX takes that Raw high res image, then Down converts it to DV.

The HVX already essentially does what a Andromeda DVX is doing, using pixelshift from a "low res" (whatever that means) chip to attain the high definition image. I suspect, that the resolution may not be much higher than a standard HVX only because the pixelshift, but the Dynamic range may well be significantly higher, and thats something I am VERY interested in. the HVX gets what 8 stops? imagine if it hit 10?!?! thats like a viper/genesis/D20. That would be AMAZING and in 1080P in variable framerates. it may be worth it just for that.

from what i've seen and read over the past year, the andromeda dvx has higher measured resolution than the hvx, better low-light, lower noise, better color space, and perhaps most importantly more dynamic range.

the andromeda should also be compared to a canon xh-g1, whose uncompressed HD 4:2:2 output produces some pretty stunning images too.

it's really great that there are so many amazing choices!

Not really; the DVX has horizontal pixel shift but doesn't use it to gain resolution. The Andromeda does put that to use, and that's how they get so much higher horizontal out of a DVX. How they get more vertical I don't really understand. But the native sampling off the DVX is not a higher-res image, it's DV res; it's Juan taking advantage of the spatial offset that's giving it an HD-class image.

Well, yes. But, it's doing so from a higher-resolution chip (960 vs. 720, 540 vs. 480) so it's going to deliver higher-res images than the andromedized DVX. Second, the HVX does actually employ vertical spatial offset (the DVX doesn't) so the vertical results of andromedized HVX could be much better than the vertical results of an andromedized DVX. Then you have to factor in that the HVX's recording format prefilters from 1920 down to 1280; the Andromeda doesn't have to. So it can keep all the internal resolution; it could perhaps deliver a true 1920x1080 signal. And then, on top of that, the HVX's recording system doesn't allow variable frame rates in 1080, but that's a limitation of the recording system. The chipset internally is running at 1920x1080 at variable frame rates. Andromeda could capture that.

So -- I still think that yes, while the HVX is doing something similar to what Juan did to the DVX, there's still a whole lot of improvement he could pull out of an andromedized HVX. A LOT.
 
I am a little confused. I keep hearing that the andromeda dvx is 4:4:4 color space, but when people talk about an andromeda hvx it seems only 4:2:2 is mentioned. Why wouldnt an Andromeda hvx pull 4:4:4?
 
Y'all are being way too Panacentric. An andromedized HVX is silly, what are they going to do, use diagonal pixel shift? The ccds of the HVX are sd, they've been pixel shifted as far as they're going to go. The pixel count is about the same as the pal XL2, and half of most 2/3" sd cams. The HVX already allows uncompressed(relatively)recording, so it's no advantage there either. I would look out for an andromedized A1/G1/H1. That would be the hotness. All the resolution of those chips recorded to 444, YIKES. What kind of resolution can you get from a pixel shifted 1080X1440 chip? Plus with 3 cams having essentialy the same processes they could offer their services to more than just 1 type of user. I think the HVX is the best camera on the market at this price point but you would see much larger gains in modifying ANY of the HDV cams before the HVX. Oooh just a thought, what about an Andromeda mod for one of those sony XDCam joints. That would take SI out of the game and give Red something to think about.
 
well barry is right about one thing, the output would be a Full 1080 X 1920 raster, with better Dynamic range.

AS far as the Xl's go, they are interlace CCD's. I dunno if it works quite the same for them.???

It is 4:4:4 if you're recording standard-def. That was one of its big advantages, that it delivers a true 4:4:4. If you use it to get a high-def image, that's not at 4:4:4, it's more somewhere sorta around 4:2:2 but not exactly.
 
We tested a DVX andromeda this weekend for a green screen shot....and let me tell you....the 4:4:4 makes a HUGE difference for keying! We had a Sony F-950 Cine Alta, an HVX-200 and a Moded DVX100B (with Andromeda) and we did a little shootout. The Sony obviously came in first but the Moded DVX100 came in at a close second totally outdoing the HVX in the results. (i am not allwoed to post the footage yet as the client hasn't cleared it)

Also the dinamyc range the Andromeda offers is amazing as well. If they are to offer an Anromeda for the HVX, I would be first in line to get one!

There are some drawbacks obviously and that is 1) you're stuck to a laptop (so it's more suitable for a controlled sudio shoot or a set) 2) I wish they would have muliple versions of the software for different OS. (not just OSX)
