How to combine MP4 files into one video

Step 1

Upload your MP4 files

Create a new project in Descript where you can drag and drop MP4s and other video and audio files to start the merging process. Descript allows for multiple files to be uploaded at once, as well as recording new video and audio directly into your project.

Step 2

Arrange, trim, and join

Descript automatically generates a transcript you can use to cut and combine your MP4s together into a single video. Just highlight parts of the transcript and cut and paste to rearrange your video, or backspace to trim. Adding a '/' lets you create scenes that make it easier to reorder, edit, and apply transitions.

Step 3

Export the joined MP4

With your MP4 files now joined, the final step is to export your new video. Descript offers various export options depending on your needs. You can download the file directly to your computer, share it via a link, or even embed it on a website.
