Does cpu speed accelerator work1/1/2023 ![]() ![]() GPU is harder to judge, but, if you were seeing (for example) about 15-20% CPU utilization and maybe 20-35% GPU utilization you'd be seeing efficient and quick rendering. Does cpu speed accelerator work plus#Plus whatever other background/OS/IO operations are happening. With one video thread on an 8-core processor, this is about 12.5% CPU utilization. Hitfilm is multithreaded, but uses one thread per video stream. This does mean it would be impossible to ever see both at 100%. Notice in the above paragraph the repeated use of "idle." The CPU and GPU, in general, are taking turns while the other is idle. ![]() Finally the GPU passes the frame back to the CPU to encode the frame into the output file. The GPU renders all effects and composting and generates the final frame. The CPU is used to calculate particle physics (if any) and one or two other things, then passes the frame to the GPU. First the CPU decodes any video frames being used - and this is where GPU acceleration is used, but it's using the iGPU built into the CPU. Hitfilm specifically has a handoff between CPU/GPU. Unless a specific effect requires it, NLEs, in general, aren't looking at any frame, other than the "current." Effects pulling data from other frames always slow things down. This is generally untrue.įor NLEs, video editors are generally "brute force" programs that work on each video frame, one at a time, then starting over on the next frame from scratch. Well, I can say something else - you are working under a common misconception that Task Manager should show your CPU and GPU pegged at 100% all the time. Does cpu speed accelerator work mp4#Those mp4 videos need to be h.264, 8-bit color, 4:2:0 Chroma Subsampling - which covers the vast majority of mp4 video.Įvery other render task is already on the GPU anyway.Īs without knowing anything about your project or your computer we can't say anything about your specific case. "GPU Acceleration in the Options menu specifically refers to GPU acceleration of "Mp4" videos on a Timeline. ![]()
