Assemble Video Clips in iMovie
You need to create a project and import video clips before you can start working on your iMovie project.
How to Split Video Clips in iMovie Into Separate Scenes
If you have long clips that contain several different scenes, split these large clips into several smaller ones, each containing only a single scene. To do this:
How to Split or Crop Unusable Footage
If some of your video footage is shaky, out of focus, or unusable for some other reason, it’s best to trash this footage so it doesn’t clutter up your project and take up storage space. You can remove unusable footage from usable footage in two ways: split it or crop it.
Splitting Unusable Footage
If the unusable footage is at the beginning or end of a clip, just split that section off and delete it. This is the best way to go when the part that you don’t want to use is located at the beginning or end of a clip.
Cropping Unusable Footage
If you want to use a piece of video that is in the middle of a longer clip, you can use an iMovie shortcut.
How to Trash Unwanted Clips
If you add clips to your project and decide later you don’t want to use them, just select the clips you want to get rid of and click the Delete key. This removes the clips from iMovie, but it doesn’t affect the original media files; they are retrievable later if you decide you need them.
