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

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
