[Dave LaRonde] “Actually, an Nvidia card that speeds up Premiere is useless in After Effects. It doesn’t help at all. I’m not at all surprised, either.”
Not quite. It may not be of the scale of GPU acceleration in Pr, but it’s significant nevertheless.

[Chris Kenny] “This is an entirely new engine. There’s no reason they wouldn’t be using it essentially everywhere it’s possible to use it.”
The precision and clarity of this logic brings tears of joy to my eyes.

[Chris Kenny] “Their Mercury engine already has capabilities similar to what Apple seems to be introducing…”
Maybe this: “we can only speculate that Apple will be introducing GPU acceleration that is similar to Adobe’s implementation” – will be less of a stretch?
Adobe’s GPU acceleration works in AE, AME and Pr – on fairly specific tasks that have been proven to be a significant productivity boost. Apple can’t say anything of the sort yet – so how about we don’t resort to rampant speculation?

[Jerry Hofmann] “The technology foundation in FCP X is second to nobody’s. It’s stunning what they are doing under the hood IMHO. “
Jerry, I could say the same thing about Adobe apps, MC, Vegas Pro, Speed Razor, Incite, Liquid and many other apps – and it may be less speculative. After all, background rendering was introduced in Incite and Liquid more than 5 years ago if not earlier.

[Chris Kenny] “Yes. It uses OpenCL.”
Anything specific? For example, Vegas Pro 10 does use GPU acceleration in some encoding tasks, but it’s insignificant compared to Adobe’s use of it.
To put it in perspective, I could maybe probably drive an F1 car but my use of it will be insignificant to that of, say, Lewis Hamilton.
If there is nothing specific – then it’s pure speculation – and then we’ll just have to wait for it.

GPU-accelerated Premiere Pro CS5 is certainly the best choice in terms of working with multiple file formats and requiring the least transcoding and rendering. It used to be Sony Vegas Pro, but with CS5, things have changed.
I believe Flip video does not require transcoding on Pr Pro CS5.x. If you can send me a sample, I can try it on my system.

GPU acceleration (one of the features of MPE) should help with smoother playback – but may not be the culprit, as decoding is still done in the CPU (scaling can be done in GPU if available).
It’s unlikely it’s a disk throughput issue.
You mentioned your CPU load is at 50% – is it 100% on one of the cores, with close to 0% on the other? Then the CPU is maxed out during playback and it’s possible that getting a supported GPU won’t make it smoother.
One sure way to find out is to borrow someone’s supported GPU and try it.

I was hoping they demoed an R3D or multi-layered H264 timeline that would hint at GPU acceleration – but alas, no. Oh well.
Thank you Dave.

[Eric Jurgenson] “Premiere. It’s the new Final Cut Pro.”
Nice sound bite. Adobe will love you for it. 🙂
