Issue with CPU performance when editing 4K videos.
Issue with CPU performance when editing 4K videos.
Hi everyone, I work with 4K video and often check Task Manager during editing. I noticed my CPU would hit full usage while rendering, but my graphics stayed under 30%. I’m not very familiar with bottlenecks, but I’m wondering if I’ve had a major processor issue without realizing it. I also saw my CPU’s GPU was used at one point, yet my 3060 wasn’t. It seems Adobe might be assigning tasks to certain parts of the system, possibly disabling GPU usage. Editing usually runs smoothly for me, though I sometimes wait for Premiere Pro to keep up. I don’t use a separate SSD for caching and edit from hard drives, so I assumed that setup was the problem. At the time, I thought my 3.60GHz CPU was adequate, but that’s a bit slow—could that be part of the issue? Upgrading my CPU might make a big difference, though it’s unclear if it would resolve this. I bought this CPU expecting good performance given my budget, but it feels like a potential bottleneck. I haven’t been paying close attention to frame rates in League of Legends lately; I just don’t check them often. The numbers I see are probably accurate, and I’ve attached some screenshots. Hardware details: Intel Core i7 12700K at 3.6GHz, 12 cores, 32GB RAM, Gigabyte B660M, GeForce RTX 3060 with 12GB VRAM, dual monitors via DisplayPort and HDMI. Editing software: Premiere Pro V24.3, using Canon RAW formats. Export settings: Media Encoder, h.264 at 1920x1080, ~16MB/s. For a video about five minutes, I don’t use proxies. Thanks for your help—I’d appreciate any extra info if you have it.
The process is going to be quite intensive, particularly when reviewing clips. It’s unclear if a bottleneck accurately describes the situation. If you’re performing an operation in an editor that acts as a CPU task—like during final export—you’ll notice near full CPU utilization, which is expected. There’s valuable information available in this discussion. https://old.reddit.com/r/premiere/commen...u_instead/ This post also references a helpful comment: https://old.reddit.com/r/premiere/commen...d/j83mlot/
No, I didn't click right-click. I reviewed the CPU graph to display all cores and threads.
It looks like you're leveraging both CPU and GPU for rendering, possibly adjusting export options so the GPU handles the workload. You might be able to customize settings to let the GPU manage rendering while you stay on the CPU side. As for me, I currently rely solely on CPU rendering at 32MB/s and it functions well.
