I have solved this problem several times by cleaning out the cache from the Preferences/Media window.

[Phil Hawes]

Thanks, that’s good to hear.

I don’t have a Tri-Level sync.
Do you know if the Deck Link can generate sync without an external reference?

This is how I output a signal from my AJA card to the Sony PVM monitor with the Ross SDI to Component converter card. Just with Genlock in FreeRun in the AJA control panel. I assume the control panel on the Deck Link has this function?

[Phil Hawes]

That’s good to hear.
I’m considering the basic Decklink SDI model.

I’m just doing HD-SDI output.

I have several Mac Pros where I had both graphics cards installed.
Some of them have the exact configuration you have, same OS, same CUDA driver, minus Resolve and the Black Magic Card.

I’m surprised you can put the Black Magic card in slot 3 since that is a slower x4 PCI slot.

The problems I had were not codec specific. But it started when I was working with a slightly larger than 2K image sequence file on a 1080 24p sequence. So I was asking Premiere to do rotation, image resizing, frame interpolation,and cropping. I had no playback.

With the ATI card removed, my playback problems were solved.

Perhaps it was not the card, perhaps there are other problems on that machine (RAM?) but as a precaution I have removed all ATI cards until I can test this out further.

If you run into any issues please post it on this forum.

Thanks for the response.

[Phil Hawes]

Agreed. That is frustrating if you want to use Resolve.
I intend to learn Speedgrade since that apparently will be supported by NVIDIA.

Regarding the combination of ATI graphics cards and NVIDIA graphics
cards on a Mac Pro, I also received the following reply from NVIDIA support:

“The combination of a NVIDIA Quadro card and ATI HD 5770 graphics card would not be compatible as there might be driver conflicts as the drivers for the Quadro card and the ATI card are not unified.”

This might explain the problems I had in Pemiere with both cards installed: no playback and crashing.

[Phil Hawes]

No, it can’t.

Only the Quadro 4000 has a CUDA driver.
The ATI card will be used for the displays.

Since I posted this message I’ve been doing some tests which seem to indicate that the Quadro 4000 works better by itself without the ATI card installed.

Does anyone else have this experience?

[Phil Hawes]

That’s my system. Except that I use an internal RAID 0.
I’m working in a University and a lot of students will be working
from Firewire 800 drives. But not if they are working with Red files!
They have the option to work from the internal RAID for effects heavy/layered sequences or with 2K and 4K files.

That was very positive! So far, my short experience has been much the same as yours. Except I’m not working with RED files.

Anyone else?

[Phil Hawes]

I have just started using Prelude.
It is useful but seems limited with AVCHD clips.
I can INGEST AVCHD files but I cannot log them (make markers).
Maybe this is a limitation of the AVCHD format.
I have no problem logging H.264 files.

The useful thing about using Prelude to INGEST AVCHD files is I can then
batch rename them using Bridge.

[Phil Hawes]

Thank you very much for the informative reply!

[Phil Hawes]

Access it to what end then, I wonder?
