Premiere Pro Renders
I just purchased a HP xw9300 with 2 dual core AMD Opteron 270s (effectively 4 cores running at 2.0ghz). I have installed 4gb of RAM, 2 SATA RAID 250gb drives (500 GB total), a 160GB system drive, Geforce FX 3450 video, and AJA LS capture card, I am running Win XP Pro 32bit.
My question is how can I get more processing power out of Premiere Pro when rendering? Compared to my old 3.4ghz Pentium 4 HT computer (ATI 800XL video), it is much slower. I was expecting a noticable increase in speed with all of the talk of Dual Core and Opteron Chips.
Looking at the task manager, I see that it is only using 25-35 percent of the processing power available when rendering. All four cores are sharing the work, so they are all active (I checked the BIOS). Is there anything like Gridiron Nucleo that will increase the workload for Premiere to something closer to 100%? Is there something else I could do to increase the power? I’ve tried setting the thread priority for Premiere to High and there was no improvement.
BTW, with After Effects and Nucleo, the render times are dramatically better.
Thanks,

What type of footage are you trying to render? What effects have been applied? Are you running any background processes? What are you trying to render to (aka output format)?

Not all functions are programed for more than one processor and/or Hyperthreading, I wish Adobe would have this listed on their website, like a list of what benifits from dual processors or hyperthreading where it can be found without pulling teeth, I used to have a list for Prem6.5 and AFX.

One Example: rendering DV captured footage. Straight cuts edit, no effects. Rendering to MPEG2-DVD using Adobe Media Encoder. No Background processes running. 1 hour long project.
P4 HT 3.4ghz = about 54 minutes
2 Dual Core AMD Opteron 270s = 1 hr, 12 minutes
Disappointing to say the least…

Same scene with Intel Dual Xeon HT set up, Premiere renders slow using about 25% of 4 processors.

With so many Dual core, Dual processors available for workstations, Adobe should be taking advantage of this additional power. I bought this system because Adobe listed it as its top-of-the-line OpenHD certified system. The fact that it is slower than my old 1 chip Pentium 4 computer is upsettting.
Maybe if Gridiron reads this, they could consider working on a plug-in for Premiere that is similar to Nucleo.
Why does Adobe recognise that “Multi-processor enabled” in the start-up if it’s not going to take advantage of that?

Problem is the native speed of the dual processors as they each would be a single, My understanding is that they only program certain SD functions as dual processor capable, HDV and HD is probably different as they are recommending HyperThreaded Processors or Duals, like I mentioned before Adobe should clarify this.

As of this moment, I don’t think that Premiere Pro gives preference to SD over HDV. It will (or should) treat all video files as elements and should assign equal priority. If this was indeed something they programmed into the application, I am sure it would in the manual or mentioned in some other place. However, I see no such mention.

You have what I was aluding to backwards, perference to HD/HDV over SD as far as processing like Hyperthreading or Multiprocessors, Running some quick tests I find that alot more effects in SD are rendered by multiple processors than used to be, running Auto Level using a AMD X2 4600 runs at approx 30% for both processors in RT, when rendered both processors show 93% and over, with a render time of 00:02:15 for a 5min clip, what effects and transitions are affected will have to wait till I get some free time, the whole exercise would be unnecessary if the proper info was listed somewhere or a statement like Ppro2 is fully dual processor capable in the SD mode.

Hmm…Interesting results. I will have to try it out on my new dual-core system.
