Is there a incompability Issue
I currently working on a project, with material from a sony ex3 cam. Right now there there is a problem with machine playing back the editted material.
Here is the weird the thing when I use the built-in sequence of premire pro for xdcam ex 1080p 24p(HQ). And playback using the external device setting monitor:2 60 1280x1024p. The playback is smooth and shows no problems.
But when I tried to use the black magic settings for the 1080i (HD 1080, 8-bit YUV, psf 23.976p) and playback using a black magic multibridge pro. My playbacks, plays a few seconds then stops. The workstation is all beefed up, I just don’t get it why it can’t playback properly in a blackmagic environment. I search all forums, reinstalled, the drivers and adobe, We even format the station last night.
Please any help, workflow, pipelines. any advice to help my situation.
Thank you in advance.
Here’s the specs on the workstation.
Windows Vista Ultimate
Service pack 2
Intel(r) Core(TM)i7 CPU 920 @ 2.67GHz 2.79
Memory(RAM) 6.00GB
System Type: 64-bit Operating system
Video card: NVIDIA Geforce GTS 250
Multi-bridge pro Black magic.

The EX3 file is highly compressed (small). The Black Magic file is uncompressed (large). Your video drive (which you forgot to mention, but I presume is a single SATA drive) can’t sustain the data rate necessary for uncompressed HD video. You need an array that can sustain at least 200 MB/s read rate to play back uncompressed HD.

I believe is a sata, I have to ask the company technical. I was just wondering. by changing this the sata to an array, would this solve the problem?.
Is there a work around on this one? I need to playback the offline material in a 16:9 viewing monitor, and the black magic is only one able to play it back.
Additional question, if data rate is the cause of the playback problem. Howcome when I play Black magic DV sequences it plays smooth? and I am still outputting it through multi-bridge.

Yes, you need an array. If you can afford it, I would go for something like an 8-bay SATA/SAS Raid5 array like the ProAvio RS8-SS (with an LSI SAS HBA). This is capable of playing dual streams of uncompresseed 10-bit HD.
I don’t understand why you can’t use the BMD card to monitor a native XDCAM HD project. I have a Matrox card (Axio LE) which plays native XDCAM HD clips. I would assume the BMD card would function similarly. Maybe someone with this card can answer your question.
DV is compressed standard definition video with a small fraction of the data rate of uncompressed HD; easily handled on a single SATA drive.

I asked my supervisor, and she told it is sata. They would probably have to request for change.
At this point, i have to work, using DV sequences for our playblacks and export the project in it’s actual res. Oh dear god, I have to export this on 16:9 DVD. Hehehe I guess I have to plan ahead.
Thank you so much Eric Jurgenson, for the help.
Good Day
