Why is premiere unable to utilize my processor?
Whenever i render stuff premiere cs5 only uses like 10% of my i7 at most. Im on win7 x64, core i7, 10gb’s ram, raid 0 media drive, 9600gt. This has made editing a really frustrating experience because premiere is very poor at handling more than two layers of HD video or effects, so i am forced to constantly render, which doesnt make much sense given that they rewrote it to be 64bit just to make it more processor efficient. Maybe they intentionally crippled it to get us to buy an overpriced nvidia card, seems like something adobe would do.

Unlike you I have not take the leap into the unknown CS5, am still using PP1.5.1 for HDV and conversion in PE4 and it still works like a charm, Adobe should be able to sort this one out, because I have a new i7 64 bit Quad Core with the approved video card, I look with interest to see if they can work your problem out ?????????????????

not sure if this post will help?

My friend bradley figured out how to enable his card, GT330M, to make full use of the GPU acceleration in Prem cs5.hope it works for you as well?

Do bear in mind that sometimes, when you work with HD footage, that the issue isn\’t the processor but the speed of your hard drives.

Do you have the latest updates to Ppro CS5 installed? What kind of harddrive setup do you have? what kind of video are you trying to process?

First, I can tell you that Adobe “crippled” nothing.
Your system has a good amount of RAM, and hopefully it’s speedy enough to be at spec…
What is your CPU configuration? 1 CPU? 2? You don’t mention that.
Also, how full your media harddrive is will affect fragmentatioon and therefore, read speed.
What effects are you specifically using?
Are you rendering because you see a red line, or because playback is simply inadequate?
All that said, you mention “HD” as if it’s one thing. Uncompressed HD requires a massive and fast harrdive subsystem, but iisn’t terribly stressful on the CPU…compressed HD runs the gamut. DVCProHD is fairly easy to handle partially at least because it’s I-frame, but once you venture into MPEG Long GOP, the decode and encode process becomes far more stressful as the compression is certainly aggressive, but the fact that tthe frames are encoded and decoded out of order make it a task where the process needs to stay well ahead of playback…of course, PPro’s MPEG previews are I-frame, so they do run pretty quickly.
MPEG2 formats like HDV and XDcamHD and EX were one thing, but MPEG4 formats like AVCHD and the video shot by DSLRs are even more complex…
As the compression you work with gets more complex, additional physical processors and cores are helpful to keep playback reponsive. Multiple processors are typically a bigger boost than one processor with multiple cores. Both are great of course, but you would traditionally have seen better performance from a system with two dual-core procs over say a single quad-core proc.
CUDA acceleration helps you when you’ve added effects (the ones marked with the “accelerated” symbol in the effects directory ) as it takes over computing the effect. The software “hack” that is out there only works on NVIDIA CUDA display cards and enables the ones that aren’t on Adobe’s approved list, usually used to enable NVIDIA gamer cards, which have no professional support.
As far as I know ATI cards aren’t supported because ATI has no equivalent technology. NVIDIA actually builds computers that use this as their core “CPU” and I know of nothing even close from ATI…it isn’t advanced GPU support…it’s quite different.
Mercury Playback Engine doesn’t need the CUDA option to run…you can also drop visual playback to half or quarter res for edit responsiveness.

To follow up with this, im working with 1080 and 720 png sequences. Ive also experienced the same issues with avchd files. My media setup is a two drive raid 0 which is fully capable of handling the bandwidth of the files. The problem remains, it cannot playback more than two layers of footage or one layer with effects without needing to be rendered. Its not defragmentation, and the raid is barely filled. If i were able to at least quickly render i could accept this, but rendering even the most benign edits take 4x realtime, and my processor, a core i7 which is quad core, is barely utilized.
Sufficed to say i am not in the least surprised at this given adobes history of delivering barely functioning products. How a company with so many hundreds of millions of dollars invested in product development can still produce and profit from such poor quality products i will never know, but perhaps when an enterprising company with its head on its shoulders releases a well engineered product and destroys the competition, adobe might open up its books and let us all in on what exactly it takes to have so much and produce so little.

I wouldn’t blame Adobe for part of your problem when you are running a halfarsed video card according to your specs listed in your first post, the 9600GT has only 64cores and usually 512MB memory which means you are going to get no Cuda support even using the Cuda card hack, only what boost you get from the software mercury engine, which isn’t enough for AVCHD with multilayers -
[David Ghast] “Sufficed to say i am not in the least surprised at this given adobes history of delivering barely functioning products.”
That’s kind of a bold statement considering how many of us are using this software and seem to be able to…muddle through.
I think that a multiple processor configuration has been recommended for AVCHD for CS5 from the time it was announced, (and PNG image sequences are not the same processor load as say, a QT clip compressed as PNG).
Multithreading across physical processors is different than multithreading across logical cores, and how the codec is configured is part of the deal…I would be curious how that figures in, as the PNG and AVCHD compression protocols aren’t Adobe code, of course.
Have you handled any other type of footage to track processor usage?
…of course if you have no other purpose here than to tell us of how Adobe makes nothing but “barely functioning” products, you may want to see how you can make that fly on the AE forum…or the Photoshop…maybe the Illustrator forum…lots of options for you.
You’re not exactly running a monster system there…you’re welcome to run any NLE you like on it and see how that works out…I’d suspect that Edius or Vegas MIGHT be able to do better on decode processor core utilization, but then they don’t have the Adobe integration or tool set, so as with all things, it’s give and take. It depends on what is the highest priority for you.

” a multiple processor configuration has been recommended for AVCHD for CS5 from the time it was announced”
By multi-processor I assume you mean a dual socket motherboard such as SR-2 running two Intel Xeon processors… ie. a server configuration… you do realise how much this kind of setup costs? Considering each 6-core Xeon is about 2k!! Could be about 4-5k for this configuration…

Do I realize how much it costs? Did you seriously just ask that question?
I need to update my system rather soon…and I have around 5K in my workstation…and that doesn’t include two Quadro display cards and AJA LHi video I/O and my fibre channel disk array.
For some reason the industry seems to think that Avid and FCP should run on big systems, but PPro should do more than either of them running on a home-use hardware configuration.
Premiere Pro is a professional video editing system…you need professional level hardware to make it perform. Just because it doesn’t prevent you from installin it or using it doesn’t mean the system you’re installing it in is adequate for all formats and workflows.
