To create slow motion videos on CapCut, you will first need to upload your video clips to the app. To do this, click the '+' icon in the upper right of the screen and add the video you want to edit.
Next, click the clip you want to use and select the 'speed' option from the editing window. This will open up a slider that you can use to adjust the speed of your clip. To make slow motion, move the slider to the left and select “Slow.” This will create a slow-motion effect for your video.
Once you're happy with your slow motion video, click the “export” button at the bottom of the window to save and share the clip.
