Problems with the 7.5 drivers and Premiere

[Jeff Anderson]

Our new system we got in late December which has 7.5 driver and CS4 Premiere running on Vista 64 is having problems like you describe. If we try and edit with any BlackMagic uncompressed SD codecs like 8bit, 10bit or MJEPG the video will be jerky on disolves. Plus it will not playback uncompressed AVI with an alpha channel. It’s strange; you can see the video with the alpha channel when you step frame-by-frame through the timeline but it will not show up at all when you play on either premiere or Decklink monitors.

If we encode video as BlackMagic DV codec everything works fine. I’m not sure if it is Decklink hardware or Premiere causing issues. Using the BlackMagic speed test we have over 300MBs read speed and over 190MBs write speed. So I really don’t think the disk raid is causing issues. Has anyone else ran into this problem?????

Yes,i reproduce the problem in our installation with win 7 x64 prof,cs4 and decklink 7.5.
Working under xs8600 and Fibber channel san disk (400mb read /250 write),we can capture well but it not possible to play fine.
Also if you use a tga o graphic with alpha the same problem appear.The preview is good in stop mode,but if you play the time line the tga or graphic not appear.
We submit the problem to bmd support and is working to solve it.We found a “temporal” solution—->apply to the tga sequence or graphic with alpa a effect MATE without any valour or anything,and now you can play fine the timeline with preview.

7.5 are working like a charm on my setup …

Although … it’s still missing a lower resolution on Media Express …

Hi Matt

Did you end up sorting out your issue?

I’m looking at building a new suite here, and I was looking to use the same motherboard.

It seems there are compatability issues regarding the i7 and X58 chipsets…so I’m keen to see if you have it sorted.

Cheers

Hi Brett,

Well… after a full reinstall I finally got my system to function, but I do still occasionally suffer from these same problems. I’ve not tried the 7.5.2 drivers yet, mainly because I can’t afford the downtime if I’m unable to get the system stabilized, but I’m hoping they will provide more dependability. Currently I only experience the problem on a very limited basis, but when the problem does pop up I usually have to dump that particular project and start again from scratch. Honestly I need to go through and update all my drivers/bios to see if I can completely resolve the issue, but I never seem to have a window of time to take the risk.

I was unaware of any compatibility issues with the i7 and X58 chipsets, are they specific to the Gigabyte GA-EX58-UD5 motherboards or do is the problem related specifically to the chipset? I googled the problem and noticed a few people that had performance issues with older chipset drivers, but once they upgraded to the latest versions their problems seemed to have been resolved.
