Sony is about to issue a 1080p camera? I saw the 24p that is recorded to tape as 1080i. Is this another one?

Update on HDV timecode issues
I've been in some off-forum discussions with Mr. Mapes of S.M., and can confirm that the Firewire stream from a 1080i camera does show correct timecode in Vegas V7, whether captured directly from tape or via DVRack/HDV hard drive recording. In fact, a recording he has made from a Sony FX1 to DVRack 1.2 shows correct camera timecode in Vegas V7.
He's also confirmed that the current version of 2.x (is that 2.1?) correctly displays TC from a 1080i camera, although Karl has indicated this may be the next build released. He has made the point to me very strongly that anything pushed down firewire by the camcorder should be correctly recorded in DVRack, regardless of how DVR displays timecode. What this means to me is that if a tape capture from say, a JVC HD100 shows timecode in Vegas V7 so will a DVrack recording of the firewire stream. I hope this is helpful to others' understanding of the status of HDV timecode in DVRack and other prosumer products - camcorder manufacturers initially agreed to a standard for HDV that was neuteral on TC position in the firewire stream, which has led to a real mess as NLE manufacturers try to figure it out, with DVRack right in the middle of the workflow. I'm just glad that the problem is slowly being recognized and solutions are finally coming. |
The "cine-look" modes on the Z1u and FX-1 are not actual 24p recording modes, but rather a way to simulate 24p in an interlaced format. These aren't recommended for 24p production.
Sony has a new camera coming out - the V1U, which uses CMOS sensors instead of CCD's, and has a true 1440x1080 progressive recording format. It can record 30p and 24p. Again, this will be another variant to the HDV spec. I don't have a lot of details about this camera yet, since there are only a handful in North America Douglas Spotted Eagle has a review here - http://www.creativemac.com/articles/...e.jsp?id=67595 I do not have timecode information about this new format, but in keeping with the axiom of "record what the camera provides," if it's in there, DV Rack should record it. Now, we'll have to wait and see which NLE reads it. :) |

Obviously SM has not even done the most basic research, like look at the software provided with the GR HD-X cameras. Even the JVC HD Capture Utility 1.0 software supplied with the cameras in 2003 showed the timecode. Of course the computer timecode is the same as that displayed on the camera display (or it would be useless). What other simple facts has SM missed? |

Thanks Karl for the detailed information.
It's clear the HDV is a floating format where manufactures do their own thing and make modifications without distributing detailed documents of what is included in the formats or not. Jeff, are you sure you were not using DV mode instead of the HDV mode when you saw the time-code? |
Jeff, were your tests with recorded clips from tape, or from a live feed? JVC has confirmed for us that the timecode generator is downstream of the live feed provided by the FireWire port, which means direct-to-disk recorders like DV Rack will not record timecode from the HD-1 and HD-10.

I just re-tested while capturing video. 1. turn on laptop, 2. start camera & connect 1394 3. start recording 4. as soon as you hit record on the camera, the timecode starts on the laptop in sync with the camera. Please let me know if you need additional testing or anything. I would like to see timecode working for the GR-HDs if its possible. |
Jeff,
I have tried to replicate this multiple times with our JVC GR-HD1U (serial number 118607XX) and have never been able to get accurate time code data direct from the camera without recording to tape first. All we have ever seen are jumbled numbers. After reading your initial post, I tried it again with the newest version of DV Rack, and got the same results. In April 2005, at NAB, I had a discussion with a JVC rep about it, and was told that the timecode generator is downstream of the FireWire port, and won't output live via FireWire. At that time, he said this was one of the things they were addressing with their new line of HDV cameras (ProHD HD-100). I've also talked with other HD-1 owners who reported a similar experience with garbled jumping timecode when recording live, and I've shared what I learned from the JVC rep. I can't explain your results - maybe JVC revved the innards of the camera? Maybe there was a bad batch of cameras in the initial run? I don't have an answer for that. The good news is that if it's in the M2T stream, then DV Rack will record it. If you can, please download the trial version of DV Rack 2.0 HD, and see if the timecode data is captured. Test out the M2T clip in your NLE, and report your results here. |
i need something like this for Mac... No dvrack support for Mac?
|
There is something called DV MOTION for MAC. I'll find you a link for download.
Actually I tried this software on my Apple Laptop and it was almost like DV Rack. I accidently deleted it. |
HD and DV Monitor Pro for Mac
HD Monitor Pro allows users with a Panasonic HVX200 to view, focus, optimize, record and organize high definition and standard definition video directly to their Macintosh computer. Users see 1:1 pixel accuracy even if they are using a screen resolution less than the full 1080 HD screen resolution of 1920x1080. This allows pixel perfect focusing in real time even on a 12 inch laptop screen. HD Monitor Pro will allow users to zoom in up to 400% or to auto scale the video to fit any size window.
