How do I AutoCrop (Reframe, Resize) a video in Kamua?

☕️ TL;DR – If your video contains action sequences, people or objects that are not in the center of the video and you need to crop the video for a mobile format, you can use AutoCrop to crop the entire video or just the Clips that have movement.

Heads Up: AutoCrop is best used on videos with movement, saving you time on tracking and reframing. For the fastest results on low-movement videos, consider Static Crop.


AutoCrop is powered by AI and it’s designed to help you repurpose your landscape videos for mobile screens, without having to reshoot or stack footage.

In this article you will learn:

Pro Tip: Before you use AutoCrop, make sure you’ve read our article about Cropping videos in general.

How to AutoCrop the entire video

To apply AutoCrop to an entire video in your Project (all of the Clips on your Timeline), follow these steps:

  1. Open the Crop Settings  on the left side navbar. You can also do this in your Project Settings .
  2. Select the desired Aspect Ratio  for the Project using either the quick icon buttons or the drop-down.
  3. Toggle AutoCrop   on (the switch moves to the right and turns purple).
  4. To see AutoCop in action click the Generate AutoCrop Preview button 
  5. Click the Draft Render (watermark) or the Full Render (no watermark) option on the bottom right of the screen.
  6. Wait for the render to be completed (rendering is done in the cloud, not on your local machine) and then view the resulting output.

Pro Tip: If you want to tweak the resulting output video, you can do that from the Outputs screen. You will need to learn how to use CustomTrack (to track custom objects, people and regions), KeyFraming (move the crop box back and forth and zoom) and Fit Video to fine tune your productions.

How to AutoCrop just one or a few Clips, not the whole video

The above method is for applying AutoCrop to every Clip in your video. But you may wish to consider applying it only to certain Clips.

It is generally much faster to apply AutoCrop only to the Clips that have movement, and to Static Crop the Clips that have no movement

  1. Locate the Clip you want to AutoCrop on the Main Timeline by scrolling to it.
  2. Locate the Clip Crop tab in the Clip Settings to your right and then enable AutoCrop for the selected clip (outlined in blue on the Timeline). 
  3. To generate the AutoCrop preview click the Refresh button on the yellow banner beneath the preview window or click Render to see the final result in your Output.
