Edit Video Clips in iMovie

1
Working With Video Clips in iMovie

All the video clips in your Photos, iPhoto and Aperture libraries are available to iMovie automatically. You can also import media from your iPad, iPhone or iPod touch, from file-based cameras and from tape-based cameras. You can even record video directly into iMovie.

Whichever method you use, after you import video into iMovie, take the time to clean up and organize the different clips. This keeps your project orderly and makes it easier to find what you are looking for.

Split Master Clips Into Separate Scenes

If you have long clips that contain several different scenes, split these large clips into several smaller ones, each containing just a single scene. To do this:

  • Drag the clip you want to split into the timeline and select it.
  • Use your mouse to move the playhead to the first frame of a new scene
  • Click Modify on the main menu bar and choose Split Clip or use the keyboard shortcut Command + B to split the original clip into two separate scenes.
  • If you won't be using one of the clips, delete it.

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 that it doesn’t clutter up your project and take up storage space. You can remove unusable footage from useable footage in two ways: split it or crop it. Both methods are non-destructible editing; the original media files are not affected.

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.

  • Select the clip in the timeline.
  • Hold down the R key while dragging across the frames you want to keep. The selection is identified by a yellow frame. 
  • Control-click the selected frames.
  • Choose Trim Selection from the shortcut menu.

NOTE: Any video that is deleted through either of the methods outlined in this step disappears from iMovie for good. It does not show up in the trash bin, and if you decide later that you want to use it, you must re-import it to the project.

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.

Create Your Movie

Now, your project should only consist of the clips that you are planning to use. Because your clips are cleaned up and organized, it’s much easier to put them in order and create your video project.
