More frame rates confirmed

Where exactly on defperception.com do you read the framerates? - I can't find them...

It's in the answers to one of the questions. Look at the comments to the articles and one of the answers spells out the framerates.
 
esperman, I was refering to the data output by Andromeda. DVCproHD is certainly a compressed format! I'd love to have the uncompressed footage the andromeda system provides.

Great question about the USB port.. Assuming that Panasonic doesn't go with native resolution chips like the recent Canon camera, I don't *think* the amount of data would be vastly different. It all depends on the pixel count of those CCDs. I wonder if Juan is using USB2 or USB? If USB2 that would be comparable (though in practice slower) than firewire.

careful now...it's NOT uncompressed HD. It's a DV type codec.

Not after Juan gets through with it. That's what Shaw was talking about. Juan's mod gives direct access to the uncompressed output of the DSP.

I thought it was prior to the DSP, but right after the A/D?

USB2!

Slower? I That depends on the USB2 host controller. In theory, USB2 at 480Mbps is faster then FW at 400Mbps. But in practice, some lowly controlers built by cheapy 2 cents manufacturers give USB2 transfer rates a bad reputation. This is one of the reasons Juan decided to go with a Mac, it's much easier to write his version 1 software based on known stable specs, then the chaos that the PC world can be with it's plethora of choices in components (good or bad).
 
I think we're saying the same thing. :)

I wonder why Juan didn't go with firewire? Perhaps it just wasn't quite enough bandwidth?
 
I don't know, I'm just guessing here, but I think it's more in line with Mac Minis and PowerBooks limitations. Both only have one Firewire connector. And because of limitations of external hard drives, as you specified, Firewire drives have a more stable sustain rate then USB2 drives. And quite possibly, the weakest link in the Andreomeda is storage. So I presume that if you need external storage, Firewire must be used, hence this leaves only USB2 as the only option. Just a wild guess!
 
Thanks Barry - I finally found it and look there:

Tosh about low framerates said:
the engineers are having difficulty with the noise floor on those.
Click to expand...

This sounds like from a real insider.... even a spokesman would a) not know this and b) not care about this technique detail..... Tosh seems to be pretty well involved in the developing of the HVX200.... spokesman AND engineer in one person... (*thinking strange things by myself*)
 
On DVInfo, Jan clarified the whole Tosh thing. It's the public face of basically the whole HVX team. So when you see an answer posted there, you can be sure that it's coming from the depths of Panasonic themselves. Now, you also have to factor in that it's a Panasonic site, staffed entirely by Panasonic employees, so there's obviously going to be a pro-Panasonic viewpoint to everything there. But when they state something factual, it's direct from the proverbial horse's mouth, so if they say it'll do something or that it won't do something, that's coming from the engineers themselves.
 
Oh... good to know! - I'll start research to get the whole picture with DVInfo etc. ....

So people of this forum are right if they say that commenting there will have a direct influence. Of course not on any changings as we all know that the first finished cameras are about to exit their oven in these hours/days....
 
Whats the need for so many odd frame rates??

TV's project 60 and 24 and some cases 30 only rite?

..or am I out of the circle of good info and im missing something??
 
Slow and fast motion effects. :) By shooting fewer frames you get fast motion when played back at 24fps and when you shoot more than 24 you get slow motion.
 
Panasonic itself explained with examples what for low framerates can be used and I will not use half of the framerates that the camera offers, but I'd have been lucky about a wider range for the PAL model. If only it reached 60fps and began at 4fps :cry: Of course I'm 200% happy with the camera. It's just: it might have been that the camera offers a framerate below 10fps (and over 50fps for PAL).
 
Well, cici, allow me to make your day -- you want slower frame rates? You'll get 'em.

(the following is based off the NTSC model, but the same principle should apply to the PAL model).

The HVX has certain supported frame rates in-camera, which include 720p at 60, 48, 36, 32, 30, 26, 24, 22, 20, 18, and 12, and 1080 in 24p, 30p, and 60i.

But that isn't all it'll do. It'll do more, I'm 99% certain. First of all, there's single-frame. But secondly, it should have at least the same shutter speed capabilities of the DVX, right? If so, you can perfectly emulate other frame rates by using the slow shutter speeds and speeding up the footage in post.

In fact, I'd go so far as to say you'll also have at least 6p, 9p, 10p, 11p, 13p, 15p, and 16p in the 720 mode, and at least 12p and 15p in 1080 mode, and you may actually have 2p, 3p, 4p, 6p, and 8p in 1080 mode as well.

It all depends on what slow shutter speeds are available. Presuming that it has the same slow-shutter capabilities as the DVX, all those frame rates will be available (with a little work in post).

So, the complete list *MAY* be:
720p:
1p, 6p, 9p, 10p, 11p, 12p, 13p, 15p, 16p, 18p, 20p, 22p, 24p, 26p, 30p, 32p, 36p, 48p, 60p

1080p:
2p, 3p, 4p, 6p, 8p, 12p, 15p, 24p, 30p, and 60i
