I am using a Mac Pro 6.1 250GB SSD, 64GB RAM, 3GHz 8 core X5 OSX 10.10.5 running Premiere Pro and After Effects CC15.
Unfortunately I am having a lot of issues with playback through an AJA KONA LHi (in a Sonnet PCIe chassis) as well as an AJA IOXT (Same issues tried both cards NOT at the same time by the way)
I need a HDMI and SDI output as I do online editing for broadcast television.
After reinstalling the Mac from factory many times, after a few weeks I get the same sort of issues with Premiere Pro. Many crashes, stuttery playback, glitches when hitting spacebar, delay when hitting spacebar etc. Every time I reinstall, a new issue occurs. However if I work with hardware playback off none of these issues occur. This seems to happen a lot with just Premiere however I need to use After Affects at the same time and that makes matters worse. Even if I disable hardware before moving back and forth between both programs, it doesn't make much of a difference. I have tried every AJA driver for both cards, still no joy. I know I have the correct AJA control panel settings for my output (I am not a novice, been doing this line of work for years) i need my output set to 1080 25p or 1080 25i.
Is it that Adobe hates AJA hardware? When I used to use Avid Media Composer I never had any of these issues....
Is there a different video card I should use that is PCIe or thunderbolt based that can output both a HDMI and SDI signal?
Any help appreciated,
When an application uses a I/O card such as the AJA card the application has to take control of the card and locks it down from the other application. Both can't use the card at the same time. Are you only having this issue when both applications are launched?
