CPU Core Number and CPU Priority You Should Allocate for Converting Videos

Author by Vita

Updated on May 27, 2021

When you're running multiple programs and also converting a video with HD Video Converter Factory Pro, you can reasonably allocate the CPU core number usage to each program based on your priority needs. Read on and learn how to take advantage of CPU to convert videos. You can also download HD Video Converter Factory Pro here:

WonderFox HD Video Converter Factory Pro offers the CPU Core Number and CPU Priority settings for users to designate CPU Usage to its process. You can change the two settings based on your own demands. So how to increase CPU usage for this software? Just Keep reading!

Set CPU Cores Number and Priority Set CPU Cores Number and Priority

CPU Core Number: How many cores does my CPU have? You can directly open HD Video Converter Factory Pro, go to the Option window, scroll down and open the CPU Core Number drop-down box. If your computer has 8 CPU cores, you can choose up to 8 cores here, and so on. When should you use this setting? Typically, if you've opened multiple programs simultaneously and are converting a large and high-quality video, it will certainly take up much CPU and your computer would even get stuck. To deal with such issues, you can allocate one or two, instead of the full amount of CPU cores to HD Video Converter Factory Pro.

CPU Priority: HD Video Converter Factory Pro also offers the CPU usage Priority setting, similarly, which enables you to set priority for the process with a Highest, Higher, Normal, Lower, Lowest, or Idle priority level to run on this program. While if there is sufficient CPU, setting the priority for HD Video Converter Factory Pro will not affect the process significantly.  

How to Prioritize CPU Usage for the Faster Conversion Speed

To get a deeper understanding of how different priority levels affect the conversion performance, here we make a contrast. From the contrast, you will know that how much time it needs to convert the same video file when setting the lowest priority and highest priority. 

As you can see from the picture, the real time CPU-usage is 85%.

We choose to convert an (1920X1080) MP4 video to AVI and the experimental data is in the following form. As you can see, it only takes about half an hour to convert the video when setting the highest CPU priority level. But if you set the lowest priority level, it is nowhere near as fast as the former.


Priority level Format Resolution Duration Size Conversion Time
Highest Level AVI 1920X1080 1:10:30 5.96GB 35 minutes
Lowest Level AVI 1920X1080 1:10:30 6GB 105 minutes

How to Take Advantage of Hardware Acceleration to Speed Up Conversion

CPU can provide great acceleration for video conversion as the test shows. But it's not the only factor to affect the program's performance. WonderFox HD Video Converter Factory Pro fully supports hardware acceleration to speed up video conversion and work more efficiently. If your computer supports Intel Quick Sync Video or has the advanced Nvidia graphics card with the latest driver installed, you can enable the hardware acceleration to achieve up to 50X faster conversion speed, which refers to as the lightning mode

The following posts show you how to make use of the Nvidia CUDA and Nvidia NVENC video encoders to convert videos

To check if your video card supports hardware acceleration, you can simply click the "NVIDIA" or the "Intel" icon on the lower right of the "Converter" interface. And you can learn more details on supproted encode and decode for hardware acceleration in

Besides being a fast video converter, WonderFox HD Video Converter Factory Pro can also fast download videos from 300+ websites. It's worth a try.
