Ok, I am still trying to get our commercial production editor working as intended so our creative services person can make the full switch to the new machine. Right now he is half editing on his 7 year old Pinnacle Liquid system that is dying. My fear is a Hard drive will fail again in that old thing and he won't be ready to fully edit on this New system...
Up till now in my other posts I have had issues with Playback and capture problems with a Blackmagic SDI card. Not sure if it is incompatibility with my motherboard or lack of support from Blackmagic but playback was dropping frames if we used GPU acceleration. We also had the problems of pixel shift when doing dissolves on the timeline that are documented on Creative Cow as an ongoing problem that Blackmagic seems unwilling to fix. Also had problems with long format captures....
My system is currently as follows:
Asus P6T7 Supercomputer
12 GB memory tripple channel
500 GB 7200 RPM boot drive
3 1 TB drives in a Raid 5 (2 TB usable space) for scratch (originally had 4 1 TB in Raid 0, one died and is out for warranty)
Out of frustration with the blackmagic card, and the fact that we are only editing to/from DVCAM SD, I decided to pull the card and go to a simple FireWire setup as that is what our newsrooms use to DSR-11 and DSR-25 decks.
Because This editor uses a DSR-1800 full size deck and was always tied to the Pinnacle via SDI/AES, I wanted to stay in that format. This was why I chose the Decklink SDI in the first place.
I picked up a used Firewire card for the DSR-1800. ($299 off of e-bay, originally a $1500 card)
I figured if this worked I could sell the Decklink SDI and be about even.
Now with the Decklink uninstalled and the firewire card connected, we are having new problems...
The capture from DV works as normal, but when you hit stop on a capture there is a very long delay.. 20 seconds to 3-5 minutes before premiere will pop up the "name this clip"... this does not happen on the DSR-11/25 decks in news.(they are much slower AMD Phenome II systems with 4 GB memory)
When I playback to the DSR-1800, it takes the deck 10-20 seconds to switch back to the iLink input. He switches the deck back and forth to other inputs for dub over from DVD and when he edits on the Liquid system. once it switches it plays fine....
Has anyone have experience editing from a DSR-1800 over firewire? I knew the option was there but have no experience using this setup.
I don't have any idea what would cause the major delay from the time we hit stop on a capture. No frames are dropped in the capture window and everything else seems to be working fine. We are not using deck control just clicking record and play on the deck and then stopping the capture when we are done.
The other problem, I wanted him to be able to use the $1600 Quadro 4800 video card so all renders would be quick and he would not have to wait like he did on the liquid system (everything rendered...)
The blackmagic Decklink SDI would drop frames playing out SD-SDI. I know SD-SDI is uncompressed format and I guess the issue could be just not enough disk speed to feed that output or there is a bottleneck in the PCIe buss. But now I found that DV does not allow GPU either, so he can't play the timeline with the GPU acceleration on at all. What a waste of $1600 on that video card if he can never use it!!!!!!
So as you can see I feel stuck. Can't seem to get any answers from Adobe or Blackmagic. now the budget has been slashed for this year and there is probably no chance I can try new hardware on anything...
At this point I may switch back to the Decklink card and add another hard drive to put the windows page file on. Harm has said load balancing across the system will speed things up.
My OS disk is much slower as a single 500 GB than the raid 0 was when I used the disk speed test. Sorry for such a long post but more information should help people know all I am dealing with..
