Auto reframe videos to fit any aspect ratio

Last updated on Sep 23, 2026

Learn how to automatically adjust your video frames based on the aspect ratios for different social platforms in Adobe Firefly video editor.

   Firefly video editor is a beta feature in Adobe Firefly, now available for testing and feedback.

Auto reframe lets you automatically crop and reframe videos for different aspect ratios, reducing the need for manual cropping and making it easier to export videos for the web and social media platforms such as Instagram and YouTube.

On the Firefly homepage, select Video, and then select Edit video.

In the Firefly video editor, select an existing project or create a new project, and then add the video to the timeline. You can also generate a video and add it to the timeline.

In the Timeline, select the video clip that you want to auto-reframe.

Select the required aspect ratio for the video clip using the Aspect ratio   icon on the upper-right side of the timeline. 

Note

The Auto reframe option does not appear if the aspect ratio of the original video and the one set in the timeline is the same. 

Select the Properties   panel, and then turn on the Auto reframe option. You can also right-click the video clip in the timeline and then select Auto reframe. 

Firefly video editor's interface shows a purple flower in snow with Auto Reframe turned on. Labels identify the Auto Reframe toggle (A), the Motion Tracking menu with Slower motion, Default, and Faster motion options (B), the Auto Reframe indicator on the clip (C), Aspect ration (D), and the motion-tracking keyframes on the timeline (E)
Turn on the Auto reframe option to automatically adjust the video's frames based on the aspect ratio.

Tip

When applying Auto reframe, use it with Detect cuts to avoid unnecessary camera panning.

Once the auto-reframing is complete, select any of the following options from the Motion tracking dropdown menu:

  • Slower motion: Use it when there is very little or no camera motion in the video. The generated video is almost static and requires very few keyframes.
  • Default: Use it for most videos unless the motion is fast.
  • Faster motion: Use it when the video has a lot of motion, so the reframing follows it. It ensures the moving object stays in the frame and adds many keyframes to your video.

Keyframes are currently uneditable; you can view them in the video timeline.

To reapply auto reframe with a different aspect ratio, select the aspect ratio. As long as the Auto reframe option is turned on, the clip automatically adjusts to the selected aspect ratio.

To further edit your video's properties, turn off the Auto reframe option and modify the transform controls and motion presets. 

After completing your video edits, export the video and use it in your projects or share it across your preferred platforms.
