It would be the footprint that the pre-filter makes it. MAny people think that this means more resolution. What you get out of the HD-SDI in either the 60 HZ or the 50 HZ version is 1920 X 1080. The footprint of the recording only reflects the pre-filter and what the codec can handle in the time frame it has to manage the data.
Best,
Jan
Go, Jan! I'm one of those that wouldn't mind paying the extra 500 (like Canon does) for the switch upgrade. And having people factory enablee this function will probably help stop the big volumes grey market sales...
Hope we get some other extra surprises! I would really hope this comes out in September over here (Hong-Kong)... Is it going to be a September worldwide release?
Thanks, Jan. Keep it up!

Personally, I doubt it. At B&H, the 200A is already reduced to $5200 from an MSRP of $6000. And while the 170 may have all the shooting assist features, as well as HD-SDI, the 200A has its tape drive, so I'm thinking they'll end up at an equal price.

However, I do hope you are right, Xtopher. Either that, or the HPX170 starts lower than the 200A when it comes out.

Is there a way to hook up the hpx170 and use pro batteries like the IDX ??

DRS compromises.
DRS compromises.
Correct me if I'm wrong but there is a compromise to enabling DRS.
Basically, there are only so many bits, or so many tones, to go around. Like the Varicam, you sacrifice the closeness of the tonal gradations when you enable the DRS. Think of the extreme where a camera has a 2 bit DSP. That's 4 shades (tones of gray) that it can accommodate - If you set the white and black levels further apart (technically a greater dynamic range) you are essentially stretching those 4 tones further apart from each other thus resulting in a more posterized look - your jumping too far from one tone to the next and if you go too far it looks very unnatural. There are only so many bits to go around. This is why there is a switch.

Jan, thanks for your clarification!
So how much memory might that be? I mean, how much memory is necessary to perform the pulldown in 720p if that's what you guys do, and to alter the timing for the frame rates that don't line up? It can't be much, just enough to hold at most a few altered duplicates of the frames which are at their highest just 1.2MP ~12bit... but all of this shouldn't matter, you could have a new PCB designed that made better use of space or that had a hard connection to a minuscule PBC to hold a bigger module of the same memory, and all you'd have to test for is shock resistance and the current memory controller to find out. There is a lot of space in the body of the HVX so there surely is some space left inside the HPX, certainly for something as small as the new PCB and hard connection necessary. The only other design necessary could be a tweak on the inside of the body piece which would also require shock testing and perhaps temperature testing for the whole camera.
I assume from your message that you feel confident in the processing power not being a limitation. I hope that is the case then I hope there might be an early release of the 200a... maybe we see a 200b later with the rest of the stuffs you got in store for us? What a perfect world that would be.

Yes and no. Yes you can transfer footage to a firewire hard disk, but the hard disk has to supply its own power. The 6-pin port on the 170 does not output bus power.

Wait, are you saying I can take my lacie d2, plug it into a wall, put the other side into the hvx and offload, no computer? Was that possible with the hvx?

That is news to me! Do you know how many hvx jobs I've been on where we just had a loader running back and forth? Granted I don't own the camera but I've used enough that I'm surprised I didn't know that.
I like that feature, a lot.
