Trim/Split/Crop/Rotate/Join a clip

After your media files (videos, images, etc.) have been imported, it’s time to start editing. This tutorial will go over arranging clips in your timeline, cleaning up your footage, editing out unwanted parts, and more.

1. Adding Media to the Timeline

There are two ways to add media from the Media Library to the timeline:

METHOD 1: Locate the file you want to add to the timeline, select it, and then drag and drop it where you want it on the timeline.

METHOD 2: Right-click on the clip you'd like to place on the timeline and then select one of the following options:

  Filmora Mac Add Media to Timeline

Insert: add your media to the selected track at the playhead. Any media that is already in the track on the right side of the inserted media will move to the right by the length of the inserted clip.

Overwrite: add your media to the selected track at the playhead, and replace any media already occupying the space your added media takes up.

Append: add your media as the last piece of media in the selected track.

Add to a new track: add your media to a newly created track which has no other media.

Note: You cannot add media to tracks with Track Lock enabled.

2. Deleting Media Files from the Timeline

Filmora9 for Mac offers a variety of ways to remove files from the timeline.

Right-clicking on the clip in the timeline and selecting Delete from the menu is also an option.

If you'd like to delete multiple files from the timeline you can simply hold the Command key while selecting the files and then use any of the methods described above to remove them.

Ripple Delete

If you'd like to remove video clips from the timeline without creating large gaps in your video, use the Ripple Delete feature. Ripple Delete will close the gaps created by the clips you removed using clips that are already on the timeline.

Right-click on the clip you want to delete and select Ripple Delete. The software will close the gap left by the clip you removed by placing the two nearest clips next to each other.
