How to Convert MP4 to MIDI

By Jamie Lisse

If you have an MP4 video file that you want to convert into a multiple-track MIDI audio file, you cannot perform a direct conversion. Instead, you have to convert the MP4 video into an MP3 audio file with Media Convert, a free file-conversion Web site. Once you have an MP3 audio file, you can convert it to MIDI using intelliScore Ensemble, the only multi-instrument MP3-to-MIDI file converter in the world, according to its Web site.

Select MP3 as the output format from the drop-down menu. Click the "OK" button to convert the MP4 to an MP3. The screens will refresh while the file converts. A download link for the new MP3 file will appear when the conversion is complete. Download the MP3 file to your computer.
