Question details
The user is unable to find or use the Trim Video command to edit videos directly within PowerPoint 2016.
- Product
- Microsoft PowerPoint 2016
- Device & OS
- macOS
- Scenario
- Editing and trimming an inserted video file directly within a presentation slide.
- Observed behavior
- The Trim Video command is completely missing from the PowerPoint interface for users on macOS.
Verify whether you are using a perpetual license of Office 2016 or an active Microsoft 365 subscription, as certain advanced multimedia features are restricted to subscription users on Mac.
Verify Microsoft 365 Subscription and Update Office
Use this solution to check your license type, as the video trimming feature on Mac requires a Microsoft 365 subscription rather than a standalone perpetual license.
Microsoft restricts the in-app video trimming feature on macOS to Microsoft 365 subscribers. If you purchased a one-time perpetual license for Office 2016, this feature will not be available in your interface.
If you do have a subscription, the issue might be caused by an outdated version of the application.
Open PowerPoint on your Mac. Click on the 'PowerPoint' menu in the top-left corner of the screen and select 'About PowerPoint'. Look for the license information to see if it says 'Microsoft 365 Subscription'.
If you are a subscriber, navigate to the top menu bar, click on 'Help', and then select 'Check for Updates'.
In the Microsoft AutoUpdate tool, click the 'Update' button to install the latest version of PowerPoint. Restart the application to see if the Trim Video feature appears.
Trim the Video Using QuickTime Player Before Inserting
If you do not have a Microsoft 365 subscription, use macOS's built-in QuickTime Player to trim your video file before adding it to your slide.

Frequently Asked Questions
Can I trim videos in PowerPoint 2019 for Mac?
The same rule applies to PowerPoint 2019 for Mac. The in-app video trimming feature is exclusively available to users who hold an active Microsoft 365 subscription. Perpetual license holders will need to trim videos externally.
What video formats work best on PowerPoint for Mac?
For optimal compatibility and playback on macOS, it is highly recommended to use MP4 video files encoded with H.264 video and AAC audio.
Why is the Video Format tab greyed out in PowerPoint?
The Video Format or Playback tabs only become active when a video is currently selected on the slide. Click directly on the video frame first to reveal these contextual menu options.
Does trimming a video in PowerPoint reduce the file size?
By default, trimming a video in PowerPoint only hides the trimmed portions during playback; it does not delete them. To reduce file size, you must compress the media via 'File' > 'Compress Media' after trimming.
