Q[michael vance] “he media was captured on one of two WideSCSI SEAGATE drives. The drives interface to the computer via an ATTO ExpressPCI UL4D. Theses drives are in theory fast enough to do nearly do realtime uncompressed NTSC 10bit without even being striped. “
IF you cannot stripe the drives there may be a directory issue. That could also account for FCP not wanting to handle the footage correctly.
A single scsi drive ( and these drives are SCSI-2/ 3 not the later SCSI 160 / 320 ie: board speed) according to the model numbers I looked at.try 2 things-
1) you need to run diagnostics on the drives. if you cannot stripe them something is wrong with the drives.
2) reformat them!!! scsi drives have the ability to bypass bad sectors on the drives. (ATA and IDE drives cannot do this) if it a bad sector the reformatted SCSI drive can work around any issues on the platters.gary adcock

[Graeme Nattress] “Ah, but you type to fast Gary….
DVCproHD 1080i is 1280×1080, not 1440×1080. HDCAM is 1440×1080, as is HDV.”How true Graeme, I was rushing to catch a plane to LA.
Thank you for the correct numbers.gary adcock

[Bill Gilman] “It seems like DVCPRO HD is a great opportunity for affordable (read: no need for Kona + SATA) finishing of HD or film material. I can’t be the first one to try doing this, can I?”
No you are not the first,
Don’t shoot yourself in the foot, HD monitoring over FW is not accurate and the 1200a deck occasionally will post black frames to the video display that do not always show on the tape.
and you would rather keep a $30K deck attached to your workstation to monitor rather than using a $2500 Kona2 Card?How are you going to store and access all of that content when you realize that every 100ft of film is equal to 1 gig of data @ 720p24

[Tom Wolsky] “t’s a kludge that Panasonic built into their cameras to reduce the bandwidth. It’s not anamorphic in the strict sense because the material is not being squeezed. Panasonic has some euphemism for it, but basically it doesn’t effect the output in anyway. When you record back to DVCPRO HD the material is processed down to this size for recording.”
Tom this is totally incorrect ( except for the re-recording comment)
sorry, this is not a Panasonic “kluge” —all of the HD formats do this “digital anamorphic squeeze”
so that it can have the ability to have the “raw” HD data stream @ 1.5 gbps , crushed onto a 9mm track on tape. Panny’s 720p native capture size as recorded to tape is 960×780, 1080 uses 1440×1080 and an HDV variant at 1280×1080. So calling it a Panasonic kluge is ignoring the facts that all of the HD formats do this so that you can get the most amount of data on the tape. Only the HDV 720 is the only HD format that does not do this.As for affecting output anything that changes the aspect ratio of your content can affect it’s outcome.
do a horizontal blur on text in any of the DV100 versions ( remember that is usable in 720 and 1080) of HD and see what happens.gary adcock

[Eli Mavros] “I thought that Aja only took care of the hardware and used BMD codecs. Or is this no longer the case?”
These 2 companies parted ways 2(3?) years ago. Apple writes the core Io drivers, AJA now writes all of the rest of their code and apps.
The current AJA products and software have been used at the Superbowl, NBA Finals, the World Series, Nascar, you see AJA products (Kona 2 mostly) every weekend when you watch live sports on tv.
There not much less forgiving than Live TV.gary adcock

[Joe Murray] “Does AJA make a PC codec? I’ve been rendering in the Blackmagic 10 bit for a long time and playing it back realtime via the IO. Are you saying these won’t play back through the Kona 2?”
yes aja makes pc versions of their HD board it is called Xena and is sold as an OEM product to companies such as Boxx and RAVE. The PC codecs are on the AJA web site.
Joe re-read the post and you see that Eli is using a kona SD board with BMD drivers- a solution not recommended by AJA, and we were talking about the Kona TV app NOT the Kona 2 board.
The Kona TV app only plays native QT and or AJA codec files- it was not built to playout other 3rd party files – it does not play Mpeg 2 files for example. (but does play H.264)hope this helps

[Eli Mavros] “I have a Kona card (not Kona 2) and the Quicktimes are 720×486 Blackmagic 10bit.”
Only works with Apple Native QT formats and the supplied AJA codecs, it does not work with the the BMD drivers. I have been able to use it on my older Kona HD board but I am running only AJA drivers.

[Eli Mavros] “Has anyone had any success using the Aja Kona TV utility? This free utility sounds like it would really be a nice little thing to have, but when I open a quicktime with it, it does not display on the Broadcast monitor like it is supposed to (I thought)…and if I drag it over into the broadcast, it is still only half rez “
Eli
this requires AJA hardware. The output of your Kona 2 OR IO should be set correctly for type of content ( 24p, 60i) and when you play the video should play out of your hardware correctly. It does not work with DV or other boards.gary adcock

[raju] “k, I see what you guys are saying. But the PowerBook comes with 2 firewire ports, a 400 and an 800. So why not connect the camera to one and the drive to the other? Are u saying that both ports on the PowerBook run off the same internal card and this will be too heavy a load?”
2 FW port yes
but only one FW bus
