Input/Output w/ Firewire 800
I am unable to output broadcast video (uncompressed 10-bit) from my Firewire array (800) to my DV Cam deck (Firewire 400). The timeline drops frames within a few seconds and stalls. No problem outputting to Digi beta, etc. and no problem outputting DV timelines to the DV deck using an external Firewire 800 drive for media. Is it a setting problem or can the computer not handle bringing in uncompressed broadcast video on firewire while outputting to firewire? Would a firewire hub help? The problem exists on my Macbook Pro 17″ and on the G-4 and G-5. Anyone else with this problem? Solutions?
Thanks!!

Not a 100% sure, but I’m going to say the system can’t handle inputing and outputing that much information over the same bus.
I would suggest getting firewire 800 card for your system and have the drives on that and the camera on the internal firewire port.
Running it through a hub is not going to do anything, because the internal bus in the system can’t handle the information.

WHile your firewire 800 array might be capable of playing back one stream of uncompressed 10-bit (I was able to do so with my G-Raids) you cannot output 10-bit uncompressed to a DVCAM deck via firewire. DVCAM only accepts a DV signal via firewire. You’ll need to copy and paste the footage into a DV timeline, render…then output.
The only way you can output 10-bit uncompressed via firewire is with the use of a capture device like the AJA I/O. Then you could connect that to the DVCAM deck via Composite or S-Video (Component if it is a higher end deck)…but then you are losing any and all benefit of working 10-bit uncompressed.

Thanks for your help…that did solve the problem. Is there any quality difference between copying the timeline into a DV sequence and just changing the sequence settings in the existing project? Obviously, the entire sequence needs to be rendered in either case.
