Video - GTX 480 performance in Adobe Premiere Pro CS5

[Jeremy_Sawatzky]

playback is simply processor based, your GPU and MPE handles all the effects. So performance of R3D playback is all your discs, and your CPU. You put CC, picture in picture, blurs, whatever, gpu will handle all of that for you in real time. Calculations for simple playback and effects differ, that's why you can't simply have a gpu run your system without a processor. If you want more seemless playback your gonna need some octo core, or 12 core power, and fast ass raids.

This is a very good way to explain it. Never thought of it that way. Regardless, before scarlet i need to hop on board with a good raid setup and i just maxed out my ram yesterday (unless i go to 4gb sticks) so im good to go i tink

Ya after getting 12 gb of ram the playback is still not great. so the next step is to get a raid setup going or get a better cpu but il live for now.

My new copy of Master Collection landed today... Sorry to here that 12GB was insufficient Jerry- Maybe someone from Red or Adobe can comment further...

well the ram isnt the problem i think. im only hittin 4 gb usage during playback. Its my harddrives and cpu. I just friggin build this computer lol and i already want a more powerful one. But hey i can playback color corrected red one 4.5k footage at half res realtime. What the heck am i complaining about. ppl pay 5 grand to playback 4.5 k footage realtime. Im only into this comp for 2.5 grand. and it can do ALOT more than half a red rocket card. haha

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

My SSD is 200+ MB/sec read. That's faster than my 5 disk Sata Raid 5.

I just built a PC with X58A-UD3R 6gig ram and a GTX 470.

I'm getting 2 layers of R3D at 1/2 res playing fine if they pull from 2 different drives. 1/4 res is probably where I'd live for editing. Still a helluvalot better than FCP. At least you can drop r3d's on the timeline, toss in some CC and go edit.

Seems to me one layer should play off any sata hard drive. They should all be at least 70MB/sec sustained read. REDCODE is typically 36MB/sec. So I don't see the drive being the bottleneck on one layer. Two layers... well now you're going to need some drive speed. 3 layers sounds like trouble.

I'll know more in a day or two but it does seem like a pretty good solution for viewing dailies and doing quick edits.

You gotta remember film guys edited movies at SD resolution forever. You don't need a big window to edit. Avoiding transcoding and proxies is a pretty big deal. Color Finesse seems like a pretty good color corrector. I know some other cool CC tools are on the way.

try to overclock it.. Themalright Venomous X + 2x 120mm fans and you're good to go.. maybe hitting 3.8GHz.. that's about 30% more CPU performance for the price of the cooler.. believe me it helps..

I may try that. Tom Wong looks to be right on. CPU seems to be a big deal.

I've done some more tests and the playback resolution really impacts CPU usage. On one layer I'm getting around 50%-65% CPU on 8 cores at 1/4 resolution. I get 100% at 1/2 rez. Adding CC or FX doesn't seem to add any CPU so the GPU is really doing it's job there. Guess I'll be editing at 1/8 probably. Still.. that's not really a problem.

Ram even at half rez is still on a couple gigs used. So I'm not sure what having 16 gigs really helps. Many layers? Many effects?

I did overclock it, my chip is actually watercooled :) but unfortunatley my chip is a bit of a lemon, anything over 3.5 (which i oced to) will bring temps to 80 celcius + but regardless, YES the ocing definitly helps no doubt. but its still an i7 930 at the end of the day.

more RAM helps with bigger projects and multi-app working enviroment AE-Pr-En.. it also helps you complicate your timeline.. how much do you have?

I didn't check the benchmarks for your water cooling system (the one I saw in the video) but usually those sealed water coolers aren't that efficient.. Venomous X is just a heat sink which you can add fans.. but it really out-perform most water coolers..

anyway, you should be fine with 3.5Ghz.. and believe me, don't upgrade to any 4-core CPU.. it won't give you more performance than what you have now with 3.5GHz.. wait for 6 core i7 970 or the i7 990X.. 990X is 6-core and will sport 3.46 GHz natively without turbo boost..
