How to Use Smart Cut

Tired of having to cut out dead, quiet clips from your video? We’ve made it easier with our Smart Cut tool in Kapwing.

What is Smart Cut?

Smart Cut is a tool in Kapwing that we’ve added to help creators edit videos 10x faster. It helps you automatically find the silent moments in your video and deletes them for you, making the rough cut process a whole lot smoother. Smart Cut works in the browser on any device, so you don’t need to worry about downloading software.

Where is Smart Cut in the Editor?

Once you add a video into the Studio, click on it and on the right side in the Edit sidebar you will see a “Smart Cut” button in the Video subsection. Once the video you’ve uploaded is fully processed, all you have to do is click Smart Cut and the tool window will pop open. No matter the video–vlog, presentation, tutorial, filmed podcast–editing will become a breeze.

How do you use Smart Cut?

Upload a video file that you would like to cut silences from. Make sure to wait until the file is fully uploaded to our site - you can determine this by checking the upload status in the Media Library. Once it has finished uploading, click the "+" button in the bottom right corner of the asset to add it to the Timeline.

Smart Cut The Smart Cut modal will appear and begin detecting the silences. You can control the threshold used for silence detection in the "Silence Sensitivity" slider in the bottom left corner. Moving the slider to the right will increase the amount of silence removed, while moving the slider towards the left will leave more of the silences in the video.

Once the silences have been detected, you can zoom in or out of the timeline in the modal, and choose whether you’d like to modify the detected silence or keep the selected silence.

To modify a detected silence, you can zoom in and use the handles on the left and right of the silence to increase or decrease the amount you want removed.

To choose to keep a detected silence, you can click on the silence. This will de-select it and it will turn gray. To re-include it in the cut, click on it again and it will turn red.
