GPU acceleration
So, I’m a bit new to Premiere Pro and still learning.
I’m working with 5.5.
I’m trying to playback some 1080×1920 DSLR footage on a timeline.
with ‘Mercury Playback GPU Acceleration’ enabled, it’s very slow and glitchy. With ‘Mercury Playback Software Only’ it’s a little better, but I still have to playback at 1/4 resolution.
My system specs are as follows:
Windows 7 64bit
i7 3.2 hexacore
GeForce GTX 570
64 GB RAMThe system is running off a 120GB SSD, the dedicated cache drive is also a 120 SSD.
I’ve allocated 60 GB of RAM to the program and no other programs are open.
The only thing I can think of is that the source footage is on an internal 2.5 7200 RPM Western Digital Caviar drive. I know it’s faster if you’ve got a RAID 0 setup.
That doesn’t seem like it would slow down playback that much though.
I’ve been trying to find out if I need a different driver for the GTX 570 but can’t really find any definite info on that.
Any thoughts would be appreciated.

The dSLR file – it’s an mp4? Not QuickTime?
Have you tried playing one of the problematic clips on any other computer with GPU acceleration enabled? Just to be sure it’s a problem with the system, not some weird glitch with the files. If not, try uploading a small clip (under 50MB) to GDrive, DropBox, etc., and posting a link here, maybe someone would be willing to test it.
Is Pr full patched (updated)?

Hi Malcolm,
You system specs suggest that the clip should easily play back smoothly. As suggested, make sure Premiere is updated (5.5.2 I believe) and also get the latest GTX 570 driver from nvidia.com site.
The 7200rpm drive should not be an issue since DSLR video is typically 24Mbps, less than DV footage!
Make sure the Sequence Setting matches your footage. Drag a clip to the New Sequence button to set that up automatically.
Thanks

You might want to roll back one Nvidia driver as there have been reports by Adobe that there are issues with the 306 driver.

I may roll back the driver later. It actually seems to player better at full res than half or quarter res…weird.

Also, playback prefers 100% rather than ‘fit’ to screen. It also prefers 75% or 50% rather than fit to screen. That said, you shouldn’t be seeing the problem’s you’re seeing.
