  
Instagram has begun testing the ability for users to upload horizontal videos running up to 90 minutes in length, marking an experimental expansion into full-length landscape video content.
The test represents a notable change in duration and orientation for the platform, which has largely centered its video ecosystem on vertical viewing and short-to-medium formats such as Reels and Stories. Allowing creators to publish landscape videos up to an hour and a half long broadens the scope of media that can be natively shared and viewed within the application.
Key Developments
- Extended Runtime: Testing introduces support for video lengths reaching up to 90 minutes.
- Landscape Orientation: The feature incorporates horizontal aspect ratios alongside existing vertical and square feeds.
- Format Diversification: The update explores long-form media hosting beyond traditional short-form constraints.
The expanded runtime and horizontal format are currently undergoing testing with a limited set of users as performance metrics and viewer retention across extended video formats are evaluated.
