How to convert audio files to a video on Mac

There are over 4.5 billion internet users worldwide, and video content has a 92% audience reach among them. With this kind of statistics, it’s evident that videos are the most popular type of content shared online today.

Both long and short videos are getting millions, sometimes billions of views, and almost 15% of millennials watch up to 20 hours of online video per week. No wonder that creating and sharing videos on social media has also become a big part of almost every company’s marketing strategy.

Plus, most social media platforms don’t support direct audio files uploads, which is another reason for the need to get familiar with how to convert audio to video. Let’s master this art so you can easily convert MP3 to video and expand the scope of your online presence!

Audio to video: convert files with images and effects

While extracting audio from a video or adding a voiceover to a silent MP4 file sounds familiar to many, the idea of being able to convert audio to video with pictures may sound a bit too surreal. Yet, it's very realistic and not at all as complicated as it might sound at first.

However, it’s important to understand the difference between the two most popular media file formats before starting the conversion process. The mp4 file format is highly versatile and can handle many media types like text, images, audio and video, whereas the mp3 format can only handle audio. That’s why converting mp3 audio to mp4 video can’t be done by simply changing the file extension and requires changes on the level of content creation.
