Hi all, sorry this is a bit of a beginners question. The background to this question is as follows; We have a lot of footage recorded as DNxHD120 QT files from a AJA Ki Pro. We need to ingest them all on multiple stations in order to get the footage in on time. One workstation consolidates fine using AMA. Multiple workstations crash out with stream errors. It's going on to an ISIS 5000.
My question is not, what is the problem, as I don't have enough info about the hardware etc to give you a good idea but instead the question is;
Does importing a 120Mbit file use the same bandwidth as digitising from tape at DNx120? For example if i was digitising 4 streams of DNXHD 185 then I would expect to need about 740Mbits right? Because it's a constant data rate across 4 streams? But how does it work with files? I thought it would be more down to the connection (firewire 800). If firewire 800 is a theoretical 800Mbit/sec connection and you plugged 6 or them in to 6 MCs and tried to AMA them all at once, would that be more the equivalent of 4800Mb/s? Would that max out the ISIS and cause errors? Sorry it's a bit vague but I'm a freelancer and I'm just poking around to see if I can understand a bit better the way bandwidth is allocated.
Any thoughts appreciated,
Cheers,
Andi
