Sometimes we download some study courses online but never find the time to watch them. In such cases, we can convert these course videos into MP3 audio files and import them to our phones. Then we can listen to the courses while on the subway or anywhere we want.

We can use “Format Converter” of Focus Video to convert videos to MP3 audio file, you can follow the steps bellow:

1. Select the video files you want to convert, and click the dropdown menu of Target preset, select the preset of MP3.

1. Click the dropdown menu of audios and select the audio track you want to keep, the first audio track would be selected by default.

1. Once all the files have been imported, and options been settled, you can click the start button at bottom right to start all tasks.
