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 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 Settings settings-24px panel using the button on the left side nav bar. 
  2. Select the desired Aspect Ratio  for the Project using either the quick icon buttons or the drop-down.
  3. Toggle AutoCrop crop-24px  on (the switch moves to the right and turns purple).
  4. Click the Draft Render (watermark, low quality) or the Full Render (no watermark, full quality) option on the bottom right of the screen.
  5. 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 Renders 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

You can do this easily on both the Simple Timeline and the Advanced Timeline, and also in the  Live Preview screen.

For the Simple Timeline and Advanced Timeline:

  1. Click on a Clip in the Timeline to open the Clip Modal.
  2. On the top right side of the Clip Modal, you will be able to enable AutoCrop for that Clip (see image below).
  3. Once AutoCrop is on, you can choose to generate the AutoCrop Preview directly in the Clip Modal by clicking on the autocrop-preview-refresh button next to it.

AutoCrop is accessible in the Clip Modal from the Simple Timeline

For the Live Preview screen:

  1. Locate the Clip you want to AutoCrop on the Advanced Timeline by scrolling to it.
  2. If you click directly on the Clip, it will open the Clip Modal, like it does in both the Simple and Advanced Timeline modes. However, you can also click on the time/frame markings just above the Clip which will switch to the Live Preview screen. You can also access the Live Preview screen by clicking on this button ondemand_video-24px on the left-hand navbar.
  3. In the LivePreview screen, the Clip Settings are on the right-hand side. Locate the Clip Crop tab crop-24px and then enable AutoCrop for the selected clip (outlined in blue on the Timeline). 
  4. Just like with the Clip Modal, you can either render the project to see the AutoCrop results or you can generate the AutoCrop preview with the AutoCrop Preview Refresh buttonautocrop-preview-refresh.
