Dear user,

The CPU load depends on many parameters, such your PC properties, input and output file settings (codec, bitrate, frame rate, frame size), resize type, and many others.

You can also increase the conversion priority in Task Manager: click Ctrl + Alt + Delete - choose Processs tab, then right click on AVS Video Converter and AVS Video Converter Host processes and choose higher priority on both processes. We do not recommend to choose higher than Above Normal to avoid problems.

Please let me know if I can be of any further assistance to you.

Kind regards

Some outdated or missing drivers may also trigger this issue. By updating your drivers to the latest version, you may fix it.
