Video - GTX 480 performance in Adobe Premiere Pro CS5

Yep full res 4k playback will want a lot of ram and a relatively hefty raid. Even REDCODE.

So a lack of RAM and slow hardrives are my weakpoint. But I was playing the clips off an ssd. And the RAM usage never spiked during playback. The CPU was always maxed out tho. This is what I don't get. Playing back 9 layers of color corected avchd only brought the CPU usage to 25%. Is one stream of redcode playing back at 1/2 res really that taxing?

[Jay Gannon]

SSD normally isnt fast enough. And yup RED footage is a different world to AVCHD for post.

[Tom.Wong]

it's a combination of 10:1 compression on top of being 4k, and RAW information too. that sir, is a LOT in one little clip. you're gonna need a much more hefty system to handle that kind of real time editing, might just have to turn your playback settings down. You should think about external raid arrays, via esata, or SAS. easier for maintenance and configurations, and running too much off the MOBO can be hazardous at times. you should also max out the ram if you can, adobe recommends min 16 gb of ram for ample play/power.

Crap. With my current mobo i can only fit 12 gb. That external raid array sounds like an Awsome idea. I've got esata off my mobo. Esata can handle the r3ds? I just might have to go and drop some cash on a wicked raid array.

[Tom.Wong]

It will certainly give you more options in speed, internal raid 0 is taxing on the mobo, and limits the amount of discs you can have. external raid can give you parity raid 5/6 or if you have ample backups, you can go all out raid 0 and get almost 300 mb/sec off the esata. A enclosure with a built in hardware raid controller does a better job than your mobo too, considering your mobo is already doing so many things for you. Faster discs really should improve r3d playback and edit performance. A lot of it relies on how fast it can read it too.

As for 12 gb of ram, it would be wise just to max that out and leave it be, 12 is a lot too, 16 is just recommended by adobe for top performance. If your not doing ultra heavy visual effects work/compositing and 3d work, you should be solid. The speed of your ram alone makes up for a lot.

Thanks tom. il look into the raid for sure now, knowing it can increase performance so much. il also pick up 6gb more ram shortly. But for now, im only working on projects with AVCHD footage. and this card is rockin it out. Thanks for all the input :)

X58A-UD3R rev 1 and rev 2 supports 24 GB of ram.. you just need to afford it.. 4 GB per slot x 6 slots.. unless you have the old X58-UD3R which have only 4 slots..

I played back RED MX footage on my 920@3.36Ghz with 9600 GT and 12GB of RAM.. played one track fine at 1/2 res with 3 CCs on.. didn't check the CPU usage.. will do next time..

Nope i have the new revision. Ya lol i forgot about the 4gb sticks. Those are mighty expensive and i cant afford those right now. I just ordered 6 gb more to make 12 tho for my system. should help. i can play back one stream just fine at half rez with 3 cc as well BUT it starts jittering a few seconds in. maybe its the 6 gb ram, but the usage isnt spiking during playback. I believe its a problem with my harddrive. the clip is just running off a 7200rpm drive, no raid or anything. what kind of hard drive setup are u using at the moment.
