Has anyone had any luck in fixing this problem? I may reinstall AE. I find also that it only happens in HD footage.

I realize this thread has been dead for awhile, but I’m experiencing this same problem. My footage was shot on HDV, but I transcoded to ProRes 422 before importing into AE. Comp is 1280 x 720, square pix. It almost feels like a cache issue- it will freeze on some frame and not update no matter where I am in the timeline. Ram previews will display a few random frames (not in sequence). It renders like this as well. I’ve tried adjusting the secret prefs to clear the cache, no luck. sometimes if i “purge all” it will update and display the correct frame, but that only lasts for a second before it freezes again. I’ve only seen this problem with HD footage.
has anyone had any luck fixing this?
my specs are macpro 2 x 3ghz quad, AE CS3, and QT 7.5 -
yeah, i’m about ready to give up and go with the sonnet. the thing is, this is the second card i’ve had (i suspected a faulty card and got a replacement). there is a four-pin power connector on the card, described as an “optional 12V internal connector for power from PC power supply” but i just called tech support again and they say it shouldn’t be needed. i’ll let you know what i find out, but i think i’m just gonna move on. thanks so much for your help.

Each drive has it’s own power supply, and the chain works perfectly when connected to the built-in bus. I will try each one individually on the card just to see if they work that way.

There are quite a few drives on the chain, Lacie FW800, i think 7 drives. AJA is going directly into the computer, which works fine. The problem is that only 2 drives show up, they are slow to react, and eventually disappear. I should note that system profiler sees the card as IEEE 1394 Open HCI, and Expansion Slot Utility sees it as “unknown IEEE 1394 Open HCI Card” running maximum speed at 1x. thanks!

Hi Jeremy,
No special drivers according to Pyro. I’m pretty sure this is a pre-2008 Mac Pro, 3 Ghz processors, 1.33 ghz bus speed. I have tried the card in multiple slots, no luck. even with the ioHD not connected, the card will only see the first couple of drives in the chain, then even those will mysteriously disappear. There are no other PCIe cards in the machine, except the display. Have you had good luck with another brand?
