How to Edit an MP4 Video - 7 Ways to Make It Better

MP4 (MPEG-4) is a popular video format compatible with almost any device. You can use it to store video files, images, subtitles, and simple animation. What makes MP4 so popular is that it preserves high quality while being pretty small in size. That makes this format perfect for both saving on your computer and sharing online. But before you get to that, you might want to edit your MP4 videos a little. This leads to a question: what’s the best way to do so?

In this guide, we will explore how to edit an MP4 file step-by-step: enhance, trim, and stabilize it; change its speed and resolution; improve the video’s audio; embellish it. You will see all of that done in a free automatic video editor called Clipify. We will also show you alternative ways to edit your files on Mac, your smartphone, and online.
