Part 1. Can iMovie Export MP4?

The short answer is: Yes, but not always. While iMovie is capable of exporting MP4 files, the final output depends heavily on your chosen codec settings: using the H.264 codec typically results in an MP4 file, whereas selecting Apple ProRes or HEVC often produces a MOV container.

This nuance leads to common confusion, as even files with a ".mp4" extension may contain encoding that certain devices, particularly Windows PCs or older televisions—cannot recognize. Consequently, many users mistakenly believe iMovie doesn’t export MP4 correctly, when the issue actually stems from the specific codec selected during the export process.

Part 2. Save iMovie as MP4 Directly (Built-in Way)

If you want to learn how to save iMovie as MP4 using the built-in export function, this section provides the complete detailed procedure. Although iMovie sometimes produces MOV files or incompatible MP4 videos, following the correct export settings greatly increases the chance of generating a proper MP4 file.

Below is the exact step-by-step guide.

Schritt 1:. Launch iMovie on your macOS device and open the project you want to export. Make sure all media clips have finished rendering or analyzing, as incomplete media may cause export failure or unexpected file formats.

Schritt 2:. At the top-right corner of the iMovie interface, click the Share (Export) icon.

Schritt 3:. From the pop-up menu, choose File. This allows you to manually control the codec, resolution, and compression settings, which directly affects whether iMovie exports MP4 or MOV.

Schritt 4:. To ensure iMovie exports an MP4 file instead of a MOV file, pay close attention to the following options: Format, Resolution, Quality, and other export settings.

Schritt 5:. How to save iMovie as MP4? Click Next, name your file, and select the destination folder.

Schritt 6:. iMovie will begin exporting the video. The export bar in the top-right corner will indicate progress.

Common Issues When Exporting MP4 from iMovie

1: Why does iMovie export MOV instead of MP4?

This happens when your timeline includes formats that trigger MOV output.

2: The MP4 file is too large

Mac’s H.264 encoding may create huge files.

3: Why won't my video play on Windows?

Different MP4 files use different encoding parameters; some players reject them.

4: Export failure due to incompatible clips

Mixed HEVC/proxy media often break the export.
