Frequently asked questions

Cropping is a video editing technique that allows you to change the visible area of a video clip. By cropping a video, you’re changing the shape of the frame in which the footage is displayed. 

Aspect ratio is a mathematical representation of the horizontal and vertical size of a video.

For example, a video with an aspect ratio of 2:1 would be twice as wide as it is tall.

Some examples of commonly used aspect ratios include:

  • 16:9 – typical for landscape video
  • 9:16 – typical for portrait video
  • 1.85:1 – common in cinema and filmmaking
  • 1:1 – square video

With the video cropping tool available in Dropbox, you’re not restricted to aspect ratios, meaning you’re free to use these examples as a guide or do something else entirely.

To crop a video stored in your Dropbox account for Instagram, select the file and click Crop video in the file preview window that appears.

From here, simply resize the frame of the video to the shape you need. If publishing to Instagram reels, you may want to crop your footage into a vertical 9:16 format.

If publishing to your Instagram profile as a post, the platform displays videos in the following formats, depending on the shape of the uploaded clip:

  • 1080x1350px
  • 1080x1080px
  • 1080×608px
  • 1080×1350px
