How to convert MP3 to MP4.

Learn how to use Adobe Premiere Rush as an online video converter to bring audio into your video editing and convert MP3s to MP4s for your video project.

Adding audio files to your MP4 video project.

Unlike video MP4 files, MP3 files are used for music and hold smaller file size audio tracks. Easily convert audio files to MP4 by using Premiere Rush — add files with narration or music to your video project before saving them as an MP4 output file. The MP4 format is desirable for its versatility. MP4s have little loss of quality at a higher compression and MP4 files work on nearly all media players — a good way to get your digital audio on more platforms.

Go from MP3 audio format to flexible MP4 with Premiere Rush.

Premiere Rush supports importing various file extensions, including video, still images, native camera
formats and audio like MP3, WAV, AAC and more into your editing timeline. Premiere Rush is an ideal
MP4 converter as it is meant for editing videos to share online, a venue in which MP4 shines.
