You'd have to ask StudioDaily, that's where I got this info.

Around $11,000 or so for the shoulder mount, $7,000 or so for the Z7u.

Am I reading this right??? 1080p or 1080i recording.
http://www.sonybiz.net/biz/view/Show...=1193315635243
From Sony: (Obviously 24p for U.S.) "The camcorders offer 1080/50i and 25p native progressive recording capabilities. The 3 ClearVid CMOS Sensor system and EIP technology create true 1080p images, which can then be recorded as progressive signals by the HVR-Z7E and HVR-S270E camcorders in the HDV format. The progressive HDV streams can be output from an i.LINK connector and used for progressive editing with compatible NLE software. The HVR-Z7E and HVR-S270E can switch between 1080p, 1080i in the HDV format, DVCAM, and DV recording, and both can down-convert material from HD to SD, and output the video signals through its i.LINK interface and other SD output connectors" So, this camera will record 1080p and 1080i to tape or CF?? That is very flexible. Although highly compressed. Since it is HDV2 it will be 1440x1080 not like 35mbit 1920x1080 from the EX. All in all this is a format most people could use right out of the box. |

Now if Convergent Designs would just make an HDMI version of their flash recorder, you could have a 1920x1080 flash master, and 2 HDV backups (one on CF, one on tape). Instantaneous triple redundancy!!!!! |
It's like the V1u, DVX100, HVX200, etc.: it can record in both interlace and progressive. Keep in mind, with the exception of the HVX200, in the sub-$15,000 category, all 24p cameras are packaging that 24p signal in a 60i stream via the 2:3 pulldown.
The HVX200 will record in 720p 24pn (native), no pulldown. I did a short film recently in that setting on the HPX500. Heath |
Real-time Pulldown for Progressive modes?
Is the HDV on the card being recorded as full progressive frames?
Lets say you're recording 1080P to both card and tape at the same time (at 24 or 25 fps).. currently, recording HDV to tape in this manner will mean it'll be done with 3:2 pulldown (in a 60i or 50i stream). No surprise - same deal over HD-SDI. However, if it's recording to flash cards as well at real time, well, would it/could it record as true progressive frames (a la HVX-200) so it wouldn't require that extra step of removing the pulldown once on the computer? |

Notice that note 2. Indicates that it actually captures at 60i and then performs pulldown. Also, the JVC HD series cameras capture "natively" in 720p. Just for the sake of accuracy... |
Heath, I've done 3:2 pulldown from 60i footage to get the 24P out of it. You're saying that the data off a P2 card, the pulldown has already been performed, and you're getting full-frame 24P off the cards?
This is what I'd hope the new HDV-to-solid state is like too.. |

Reading this statement they clearly state 1080p recorded as progressive signals. 60p??? or is it 24p/30p over 60i?? And the progressive streams can be output and used for progressive editing? Heath, you're probably right. The way they're wording it with "true 1080p" got me excited. Thanks. |

Tape = 60i with 24P 3:2 required (most likely) Card = ? |
Quote:
"The corresponding video format is HDV1080:60i/24p/30p DVCAM/DV:480/60i " But what I haven't been able to find, is how they are achieving the 24p. I am going to speculate that they are using pulldown from the 60i. My guess is based on the specs for the M35: "Video signal 1080/60i NTSC EIA 1080/60 i system, NTSC color, EIA standard method 1080/50iPAL、CCIR 1080/50 i system, PAL color, CCIR standard method " But that is a seriously uneducated guess. |
Thanks Joel. But what does this mean? (From Studio Daily)
"Like the EX, which is an XDCAM recorder that doesn’t record to XDCAM discs, the new S270U is an HDV recorder that doesn’t have to record to HDV tapes. Beyond capturing and recording images as 60i using 2:3 pulldown, the S270U’s native progressive recording mode lets it output 24p and 30p (25p on the European version) via iLink." Does the CF recorder hook up to the iLink (IEEE1394) port?? What do they mean by beyond capturing and recording 60i using 2:3 pulldown? Is this true 1080p/24 to iLink or is it performing pulldown extraction from 60i? Sorry guys, just trying to decipher the "marketeze". |

Just so we're all clear here: That's talking about 24p mode. Heath was referring to 24pn mode. The "n" stands for native. If you shoot the HVX200 in 24pn mode, you're only getting 24 progressive frames of data written to the card per second. That's about as true of a 24p as 24p(n) gets. As far as I understand it, the HDV specifications dictate that there HAS TO BE 60 interlaced frames of data written to tape every second. This is why JVC broke with the HDV consortium guidelines and invented their own flavor of HDV they call "ProHD". Their 720p24 format is proprietary (and pretty good). By no means am I an expert, I just read a lot. The previous paragraphs are what I've gathered from my readings in the past. Someone please correct me if I'm wrong here. I very well could be. |

Okay. I talked with my local dealer and this is what he said. They made the camera recording switchable to record 1080i or 1080p. Going to tape is a 60i stream like Robert said. The CF module has a label mark that says "Progressive" . The module can record 1080p/24 or 1080p/30 in m2t. But it's not the same GOP as traditional HDV2. (He didn't know what it was). The module can record m2t,dv, etc. in 60i (HDV2 Which he's sure includes 24p like the V1) and the 2 "New" progressive modes 1080p/24 and 1080p/30. So we don't know what edit systems will support the new GOP. He said FCP should have it in the next release but he thought Avid Liquid should work right now and he didn't know about the others. So it sounds like Sony is using the m2t file format with a different GOP for 24/30p. Sort of like JVC did with getting 720/60p to an HDV tape. They went from a 6 frame GOP on 720p/24/30 to a 12 frame GOP to get 60 true progressive frames on the 200 series cameras. Note: (Not everything is forced to be in a 60i stream by the HDV spec) Cheers. |
Quote:
For what it's worth, FCP can export HDV 1080p24: twenty four frames per second, in a GOP HDV format. So the HDV spec has some leg-room it appears. The last thing I want when moving to a solid state format, is having to re-render all my data to get 60i to 24P - that'd be stupid - the technology is better than that. |
Quote:
To be clear, when I'm talking about forcing into a 60i stream I'm ONLY talking about going to tape. Thanks in advance for explaining this to me. |
Quote:
We know how the tape works: to tape is 60i - with the 24P 'contained' within the stream. To card it could be true, 23.976 frames a second (also known as 24P). Not 60i. |
Ethan,
You're probably right in that you can't fit a full 1440x1080 24p 25mbit HDV2 in anything but a 60i stream to tape. But JVC did fit a 720/60p 19mbit HDV1 stream to tape. But this is excellent news for indie film makers that want interchangable lenses and don't have to use a program (like Cineform) to deinterlace and extract 24p from a 60i stream. I bet most edit programs will support the new GOP soon. |
Okay, I got confirmation from expert Graeme Nattress: 60i streams are needed to put 23.98 fps signals to tape. HDCAM can handle native 24p, but not minidv.

The CF card version will work just like the EX1. True 24p/25p/30p written to the card. Thus, it could be like 24pn. However, I haven't seen anything that shows longer recording times for 24p! Which could mean 24p is carried within 30fps. (4 frames converted to 5 frames using a 2-3 cadence.) The 6 unwanted frames every second can be flagged and dropped during capture. Or, captured and ignored during editing. PS: How is Canon's 25F recorded to tape? It doesn't use 2-3 pulldown. |

"1080/24PA (Advanced, or 2:3:3:2 Pulldown) The Panasonic HVX200 can record 1920 x 1080 at 24P (actually 23.976), with 2:3:3:2 (Advanced) pulldown, and this is the recommended recording mode for transfer to film. The movie is stored on the P2 card as a 1920 x 1080i MXF file, at 29.97 frames/sec for compatibility with standard HD editing systems such as FCP-HD and Avid Express Pro HD. To play back the .mxf files in DVFilm Maker, drag the file into Maker and it will appear in the playback window. To remove the pulldown for editing at 24P and convert the .mxf file into a 24P Quicktime or AVI, 1. Drag the .mxf file from the P2 card virtual drive into DVFilm Maker. 2. Special playback controls will appear. Note the player does not play back audio. 3. To convert to 24P, select 24P Edit options, remove 2:3:3:2 pulldown and 23.976 fps exact. In Advanced Options, choose User Selects Output Folder and browse for a folder on your disk drive. Also select "Always Make Quicktime" if you want Quicktime format (otherwise an AVI will be created). Other options may be required, see "Choosing a Codec" below. 4. Close the 24P Edit options box if required and hit Start. When finished, use File->SaveAs. 5. Clips can also be batch converted by dragging them into the batch window. 720/24P or 720/25P recording mode Maker will also process the 1280 x 720 frame size. In this case, no pulldown removal is required, Maker is just used to convert to Quicktime or AVI format, and if required, recompress to a different codec. To convert the .mxf file into a Quicktime or AVI, 1. Drag the .mxf file from the P2 card virtual drive into DVFilm Maker. 2. Special playback controls will appear. Note the player does not play back audio. 3. Select "Deinterlace" and then UNselect it, to turn off all processing of the video. 4. Select Advanced Options. 5. To convert to Avid or Apple Quicktime format choose "Always Make Quicktime." Other options may be required, see "Choosing a Codec" below. 6. Close the Advanced options box if required and hit Start. When finished, use File->SaveAs. 7. Clips can also be batch converted by dragging them into the batch window." Here it is stated again in the user manual: "DVCPRO HD Recording onto a P2 Card The AG-HVX200 is the compact camera-recorder to offer 1080/24p (over 60i) shooting. You can also select 1080/60i, 1080/30p, 720/60p, 720/30p, or 720/24p in HD. The multi-codec lets you choose either DVCPRO 50, DVCPRO, or DV format for SD (480i) recording" I'm not making a case for or against the HVX200. It was posted earlier that the HVX200 records 1080 24p with no pulldown to the P2 card. I haven't found any documentation that supports anything other than the HVX200 accomplish pulldown in camera to get it done. This from Panasonic documentation and other websites such as I referenced. There certainly could be modes that I am not aware of, but I haven't found this one. I'm not saying that's bad, but other than the fact that the HVX200 is putting the video on a P2 card, the process it uses to achieve 1080 24p is not unique among cameras under the 15k price tag that the writer made reference to. In fact, it seems very similar to the JVC HD series process. Being we are all trying to learn the facts, the little details can be important. And as I say that, if one of the HVX200 wizards has a better explanation, or can explain where I am misguided I would welcome that info. I really admire this camera and want to understand all of this stuff. If the HVX200 records 1080 24p at full resolution, to tape or P2, I will buy one. But so far, I haven't found that to be the case. |

Only in 720p (and maybe 480p), you can use 24pn (native), no pulldown. You can fit around 40 minutes of 720p 24pn on two 4 gb cards. Maybe two 8 gb, I forget. Whichever was the max when the HVX shipped.
For my film Hellevator, we used the HPX500 with four 16 gb P2 cards. We got around 170 minutes in 720p 24pn. I know Graeme well; he has helped me out a lot. Most recently, he aided me in an article for Videomaker about the State of Imaging (CCDs, CMOS, etc.). He and I speak almost daily. Here's a picture of Rob Lohman, Graeme and I (I'm first, Rob's second, Graeme's third, left to right) at NAB 07. I've lost about 20+ lbs. since then, btw. :-) heath ps-Hope I'm cool! |

Applications like DVFilm Maker, RayMaker, and plugins like Raylight for Vegas can remove the pulldown without any recompression or loss of quality, they simply skip over the redundant frames. |

The only thing I was pointing out, is that the HVX200 performs pulldown to achieve 1080 24p... not that the image quality suffers because of it. It is simply the process that it uses to produce 1080 24p. This new camera from Sony, appears to operate in a very similar way to the HVX200. That's all. |
Marcus is the man; he owns www.dvfilm.com and I highly, highly recommend his software. I've used DVFilm Maker a lot. I reviewed his "Shooting Digital" book here.

But that's not an accurate statement. Rather it acquires 1080 at "true" 24p and in order to make it compatible with older editing systems, it then adds pulldown to convert it to 60i. But removing the pulldown restores the original 24P. |

Thanks. |

Love the options on the Z7! I'm curious, with the CF unit on the back of the Z7, where does the battery fit?
|
Adam,
I wondered the same thing myself. |
Quote:
Another untrue statement. Unfortunately Panasonic is guilty on this one too so I understand everyone's confusion. When the camera is shooting 24P it really is sampling the sensor at 24P. A simple experiment proves this is true. At 24P with the shutter speed set high (around 1/250 for example) you pan over an object rapidly, and then look at the results frame by frame. If it was converting 60P to 24P you would see either blended frames or slightly uneven steps. You don't. It's perfectly even and clean, because it's sampling at 24P just as it should. |
Marcus, Joel, Heath, anyone else:
It seems that we're gotten off the topic of discussing the new Sony cams and have gotten into the nuts and bolts of understanding how different camera systems handle the recording of 24p to their various media. Should we create a new thread to discuss this further and leave this thread to it's intended purpose? If you guys agree, then I'll start the thread. I would like to continue this discussion, but I'm not sure the Z7/S270 thread is the right place to do so. |

Start it here. Leave a link and we'll all join up. But I feel this relates to the cameras.

Ok guys, I've started the geeky technical debate/discussion about 24p here
See you there. I have some questions. |
Quote:
New questions. The price of the Z7 is comparable to the XDCAM EX, any guesses on how it compares picturewise, particularly low light? Any guesses on street price? |
I think it goes where the handle on the right side is. BIZARRE! Hope they take the F970s!
