Question details

The user wants to export a vertical PowerPoint presentation as an MP4 video at exactly 1080 x 1920 resolution on a Mac, but finds the output resolution is reduced.

How to Export a PowerPoint on Mac to MP4 at 1080x1920 Resolution

Product: Microsoft PowerPoint for Mac
Device & OS: macOS
Scenario: Exporting a vertical presentation (9:16 aspect ratio) to a high-quality MP4 video format for digital signage or social media.
Observed behavior: PowerPoint for Mac exports the video at a lower resolution than the original 1080x1920 slide size, as the Mac version provides limited export-quality controls and lacks custom resolution settings.

Before you start

Ensure your presentation slide size is correctly set to a 9:16 vertical orientation (1080 x 1920 pixels) before attempting to export.

Solution 1Recommended

Use Presentation Quality Export Settings in PowerPoint

Maximize the built-in PowerPoint for Mac export quality, which provides the highest possible default resolution.

Since PowerPoint for Mac does not offer custom resolution or bitrate settings, choosing the highest preset is the simplest way to improve video quality directly within the app.

Open the Export Menu

Click on 'File' in the top Apple menu bar, then select 'Export...' from the dropdown.

Select MP4 Format

In the export dialog box, change the 'File Format' dropdown menu to 'MP4'.

Choose Maximum Quality

Under the 'Quality' section, select 'Presentation Quality' to ensure the highest built-in resolution, then click 'Export'.

Resolution limitation: While this yields the best native Mac quality, it may still slightly downscale from a true 1080x1920 custom resolution.

Solution 2

Export Slides as Images and Compile in a Video Editor

Bypass PowerPoint's video compression by exporting high-resolution images and combining them into an exact 1080x1920 MP4 using a third-party tool.

Solution 3

Export Using PowerPoint for Windows

The Windows version of PowerPoint offers advanced video export controls, including higher resolution capabilities.

Frequently Asked Questions

Why doesn't PowerPoint for Mac allow custom video export resolutions?

Microsoft currently limits the Mac version of PowerPoint to three preset quality options (Presentation, Internet, and Low Quality) to simplify the interface, omitting the custom resolution and bitrate settings found in the Windows version.

How can I request Microsoft to add 1080x1920 MP4 export on Mac?

You can submit a feature request or vote for existing requests regarding custom video exports on the official Microsoft Feedback portal at feedbackportal.microsoft.com.

Will exporting to MOV instead of MP4 fix the resolution issue?

No, changing the format from MP4 to MOV in PowerPoint for Mac uses the same underlying quality presets, so the output resolution limitation will still apply.
