lauri,
Why do you change the m2t files to avi?
Bruce Yarock

the Cineform "intermediate codec" is used in Premiere Pro editions to improve editing capablities and color correction, as well as to reduce strain on the System due to extensive processing required to edit and render in native HDV. In the HDV .m2t files, each frame rendered requires interpolation from the prior frame. In an .avi file, each frame stands on its own. Major issue is it takes about 4 to five times the drive space for a .m2t to become .avi.

Not really an issue in today's world, though. You can find some really great deals on 1TB raids and 500GB HDs. Space is less of an issue than CPU, IMO.

ciao,

That's the Cineform codec: It includes a program called HDLink. I open the files on the CitiDISK HDV with HDLink, convert the m2t files to avi-files, and store them on harddisk. Then when I open these files with Premiere Pro, the procedure is the same as if one had dv-avi files.

I just called at Shining technology asking what is the speed of
the laptop HD's that they use for their HDV models and they said
it's 4200 RPM!!.....not even 5400 RPM like the nNovia QC.....

I can't imagine my workstation working with either speed in my HD's....
7200 RPM it's ok for plain DV...I dont know HDV...but I am guessing
those 10,000 RPM Raptors were invented for something....
And those Maxtor (SCSI HD's running at)15,000 RPM......oh well....

I know that at the present time you only CAN buy 7200 RPM laptop HD's
Probably I will wait for the Catapult and see if I can configure something
with a 80GB 7200 RPM Hitachi antishock Laptop HD....

Caesar: I'm sure someone will tell me if I am wrong, but I think HDV captures at the same bitrate as DV SD, so if you should be able to capture HDV on any hard drive fast enough for DV. Problem comes with processing the image at the same time on a capture monitor on the computer. Premiere Pro actually instructs you to monitor on camera's LCD.

Chris:
Thanks for your responce.

You are right...I have a friend that has the Sony FX1
and he told me that when he captures it takes for the MPGE-2
file the same HD space as the AVI file of Standar Definition.
About 13.5GB for each hour of footage.

But also there are other codecs for HD that require more
space like DVCPro HD and 50 for the Panasonic HVX200....

I think that for some of the current DTD's Recorders in the market
they use 4200 and 5400-RPM HD's because that's what it was
available a couple of years ago.

Now with the introduction of the 7200-RPM 2.5" Laptop Hard Drives
They may star building the recorders with this kind of HD's....
But first they have to get rid of his OLD inventory first....

Cesar.

So can we confirm that the CitiDisk HDV does indeed work with the Sony FX-1?

Any issues? (Thanks)

Citidisk with JVC HD100?
 

Anyone had success with the Citidisk and the JVC HD100U?

Has that firmware upgrade come out yet that lets it play back or store timecode?

Bruce, Just realized that I'd read you question "HOW do you change .." instead of "WHY do you change ...". The answer is, the mpeg2 format does not lend itself to editing. Moreover, the TV-stations do not want to have master material in mpeg2 format. Thus, it is better to change the format immediately to something else.

Cineform codecs (Aspect HD and Prospect HD) are in my experience just wonderful. After I've edited using Cineform codecs the doors are open to any direction.

In short, the question is of maximizing quality between shooting and creating a master tape/file.

Scheduled to get CitiDisk HD to test for a week.
 

a local vendor has offered to provide me with a citidisk to use for a week with my HVX200. Seems there has been difficulty in dealing with recording in the mxf format, and files are written with some proprietary "workaround". But, have been told that manufacturer (Shining?) wanted to find a few HVX owners to test out the drive and report back. That should be within a couple of weeks. Looking forward to it. I welcome suggestions for tests.

ROFL..
These little drives are often barely able to handle the HDV 1080 stream of 25 Mbps. That HDSDI port on our XLH1s export footage that is roughly 1.485 Gbps!
If the drive were even close to fast enough, it'd be great! -except at 100GB it wouldnt hold any decent amount of footage! You'd need some sort of compression module to make the drive able to hold any reasonable amount of footage.

The smallest HD-SDI Direct-to-Disk recorders I've seen are rackmount setups about the size of most home PC towers out there (but layed flat) and have multiple high speed hard drives that collectively hold 1-2 TERRAbytes. And even in Cineform compressed mode (180-250 Mbps) still only hold ~19hours of footage (depending on compression rate and hard drive configuration).

But I share your assessment- an UNCOMPRESSED 10-bit 1920x1080 capable HD-SDI recorder of decent capacity that you could mount to a camera would be darn cool wouldnt it?
