Issue with low frame rate and warping in Adobe Premiere PRO CC
Issue with low frame rate and warping in Adobe Premiere PRO CC
Hey everyone, I’m not new to this. I work as a PC technician and have experience with design software like Photoshop, Illustrator, and InDesign. Recently I began learning Premiere Pro, and since I’m familiar with other Adobe CC tools, it was quite straightforward to grasp the basics. However, I’m encountering performance issues when using the warp effect to reduce motion in a clip. The source files come from a Sony MC2000e and are 1080p at 25 frames per second. I have GPU acceleration enabled in the project settings, but playing back clips with the effect applied causes noticeable stuttering and high CPU usage—often at 100% utilization. My questions: Should the processing be moved to the GPU? Is my CPU slow enough to handle it? Are there any settings or plugins I should adjust to improve performance? If upgrading is necessary, should I replace just the CPU or the GPU? My current setup includes an Intel Core i7 920 (16GB, 1887MHz), Corsair Vengeance RAM, ASUS Sabertooth X58, and a Noctua NH-D14 cooler.
Hello, Your setup can definitely handle editing in CUDA-based NLEs. The Warp stabilizer doesn't fully utilize the GPU's power. I'm pretty sure the analysis work is being done entirely on the CPU. I verified this myself and saw no GPU activity during the "Analyze in Background" stage (I use OpenCL, but others agreed it should run on the CPU). Once processing finishes, the effects are moved to the GPU. The CPU's performance isn't actually slow. In comparison, the i7-920 CPU performs just as well as a k-part i5 (source: http://www.cpu-world.com/Compare/456/Int...7-920.html). But keep in mind—your rendering tasks are manageable. Another tip: if you're dealing with AVCHD files, try converting the .mts files to .mp4 using the Media encoder from Adobe. They’re roughly 25% smaller and work smoothly without issues. As for upgrading, it’s probably not necessary right now. Remember, the NLEs rely on serial CPU processing; GPU boost is only helpful for rendering. A stronger GPU like Quadro or FirePro adds little extra value unless you need it.
Thanks for your response! There are additional issues to consider. The 560Ti isn't officially supported by Adobe, though they mention it should work after issuing a warning about unsupported status. I even tried the GPU hack before premiere without receiving that warning. However, I can select the Mercury GPU rendering engine. The issue remains: my CPU is fully utilized when applying the effect, and the clip appears red in the timeline, indicating it won't play back in real time—even at half resolution. It might be that my scratch disk isn’t fast enough. The source files are stored on a 7200rpm Seagate Baracuda drive, and even with WMP or VLC, it still causes lag, frame drops, or audio issues. I’ll attempt to switch to my SSD as a scratch disk to test its impact. If that doesn’t help, I’ll explore hacking the rig and installing the latest mac CUDA drivers to see if it resolves the problem.

I'm still learning a lot. After a while the problem appeared in OSX too. I assumed it was related to Windows and CC. I made a simple mistake: I played back the clips straight from the timeline without using Sequence>Render effects or pressing Enter. It's clear the process in Premiere Pro is quite different from what I used in Indesign and Photoshop.
