HPX170 - A Second Look

Barry, do you know if the SDI Out is switchable between SD and HD like with the EX-1? You could dump to a DigBetadeck in SD for networks that still use SD.
 
HD-SDI & P2 simultaneously

HD-SDI & P2 simultaneously

I searched the forum but couldn't find an answer. I'm assuming the answer is yes, but just want to confirm that you can record to P2 and capture from HD-SDI simultaneously? I have an AJA ioHD and would like to capture ProRes 10bit when possible but also always record to P2 for backup. will the timecode spit out over HD-SDI match the P2 timecode? Also, does anyone know if ProRes HQ & regular are both 10bit with different compression levels or is HQ 10bit and regular 8bit? I've found conflicting info on the internet. the apple white paper only mentions 10bit and should be the most reliable source methinks.

Yes, of course.

It has embedded timecode in the HD-SDI data stream; I can only assume that it will match the P2 timecode frame by frame. I haven't tested it, but I also can't fathom why they'd have separate timecode...

It can't be horribly off... I simply couldn't see Panasonic dropping that sort of thing on the 170.

I'm almost positive both are 10bit.
 
Just had a chance to have a play with a preproduction HPX171 - the pal model,

First impressions - nice. It sits in your hand perfectly and is so well balanced.

Yes - the LCD is a huge improvement over the 200, with EVF detail turned off the LCD looked the same as the EVF detail turned on on an HVX - with it turned on - Wow.

The new focus assists are great.

The waveform and vector scope are very nice.

NTSC Pal Switchable - still no positive answer. We might have a hope.
 
No, i didnt have any p2 cards with me and shooting off stuff on a still early preprod model isnt always a great idea.

The quality i saw on the lcd was awesome, a lot less noise than im use to seeing on my Hvx. Then again.. i was only judging off the lcd screen.

The camera still has a bit of a way to go design wise... theres a lot of very strange button designs on the one i saw.. the power button for instance.
 
Does anybody know if we can sync timecode between 2 cams without having to switch modes on 1 cam, lose a few frames, therefore have to film the lcd, etc etc.
Thought this was such a great selling point in the hvx200 that they didnt quite manage to pull off. Be nice to have a little less math to do in editing.
 
I need Pal/ Ntsc switchability because I work with both formats everyday .This is the Only reason I would purchase Hpx 170 over a Canon XHA1.
I need this functionality so that I can use the pretty progressive images the camera produces. If not canon xha1with upgrade here I come.
So can someone please tell me will the hpx170 have this feature or not .
How difficult is it to answer this ?
And please Panasonic dont offer it as an upgrade just put it in there .
Swicthability = Globalization = $$$$$
 
That's why I want to know about the swicthability. BecauseI'm drooling about the Hxp170 and I dont understand why there is no definitive answer.
I just wouldn't trust the camera if this feature became a last minute decision . And if they decide this next month or so would the camera work properly. I believe that this feature should be tested thoroughly.
And if its something you can just pop in the camera... Panasonic leave in there.
Please think ATSC. All formats baby.


OK back to work.:undecided

So from the lack of response, my estimation of the work-load of R&D required, and money, and the little time left for the release, then I suppose that the DRS in 23.976fps is never going to happen on the 170 right Barry?

Just read Jan's Posts on page 14 of this thread.

ATSC is perfectly capable of outputting PAL signal . Your edit, movie or whatever you produce just needs to be digitized or properly encoded.

http://en.wikipedia.org/wiki/ATSC_Standards

So your HDTV with atsc tuner is capable of playing back 25 or 50HZ frames per second .

I don't believe this is accurate. The ATSC standard adopted by the FCC for DTV doesn't say anything about 25Hz or 50Hz. You can read document A53 and you'll see there's no mention of 25Hz or 50Hz. The ATSC didn't standardize 25Hz/50Hz until document A63. The FCC adopted 18 DTV formats, none of which are 25/50Hz, and no ATSC tuner sold in the US (at least) needs to support 25 or 50Hz, as far as I know. And I know for a fact that my HDTV, a Sony XBR, won't play any 25Hz or 50Hz signals (which was most depressing to discover, I can assure you.)

The ATSC Table 3 denotes all 18 formats offered and supported by ATSC tuners, and those are:
4:3 640x480 @ 24p, 30p, 60p and 60i
16:9 704x480 @ 24p, 30p, 60p and 60i
4:3 704x480 @ 24p, 30p, 60p and 60i
16:9 720P 24p, 30p, and 60p
16:9 1080 @ 24p, 30p, and 60i

PAL/25Hz/50Hz isn't included in the ATSC DTV tuner standard as approved by the FCC.
 
Yea, but I was asking about it more in depth in page 15 or 16

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.

Sorry to be a pain, but that's the way it is!
