That applies to the Blackmagic device, John.
I do believe CS6 now allows CUDA with FireWire output.
I haven't tried it with CS6, since I have no use for DV tapes anymore, but hardware CUDA is completely irrelevant for exporting to tape, since the tape is far too slow to profit from CUDA acceleration. Say you have two hours of DV AVI material to export to tape, that takes two hours. Exporting the same timeline to disk takes only 14 seconds on my system. And that is without CUDA acceleration.
Hi, what is the configuration of your system Harm? You can more details?
CS6 will let you play directly off the timeline to DV or print to tape using DV with the MPE on. In PAL land we do have a field problem however - all DV output through hardware (ie not making a DV file) has the fields the wrong way round.
When previewing off the timeline you do not notice so much unless you have "both fields" enabled. They you will see a peculiar wobble on shots. The best soloution we have found, if you really need to export to DV, is render the timeline to a file (we make a standard DV PAL file), put it on a new timeline and invert the fields for that file. Then export to tape works fine.
There is not reallt a great solution for playing live off the timeline apart from only watching a single field output.
I do not know if it is problem for NTSC but I am guessing it is not, which is why it was missed.
The complete story about my system can be found here: Planning & Building a NLE System. It is quite long and contains my considerations for all the parts used, how I went about building, the final results and whether it was worth it, the price tag and what components, with the links to them I ended up using.
One thing to consider in my example of a two hour DV timeline, is that there were no effects or transitions, only a single track and writing that to disk took 14 seconds, effectively meaning a sustained write speed of around 1760 MB/s. This is only possible on extremely fast raid arrays. But writing to a single SSD of the same material on a i7-2600K with 32 GB and a GTX 660 at stock speed takes six times as long, 84 seconds versus 14. Still a respectable write speed of around 294 MB/s.
