How does processor performance affect Video Editing?
For peak video editing performance, your workstation matters a lot. The resolution of the video you are working on will determine how long your PC will take to prepare each clip. Additionally the type of source files and codecs you use will have some impact on the speed you can edit, playback, render and export your projects.
Decompressing files from your camera will put a heavy load on the GPU and CPU, you will need to find a processor that has the right balance of the two.
Processor clock speed is a very important factor in performance. This is typically seen to scale directly with increased clock speed. The number of Processor cores is also important to prevent performance from tailing off.
Processor performance for Video Editing Software
For the most part all of the different video editing software on the market has similar hardware requirements. All of these see increased performance as you scale up with multi-core processors. However be aware that there is a trade-off. A higher core count will lead to reduced clock speeds that can negatively impact your video editing performance.
Choosing the right processor
To ensure proper video performance the best approach is balance. Don't go high end on the processor if you are going to go with a single GPU on the flip side don't get a high end GPU and slack on the CPU. You are only as good as your slowest component.
