Split and Trim Video on Mac 

Filmora for Mac provides several ways to split footage into separate clips and trim away unwanted sections. Use the playhead Split button, timeline Scissors tool, or clip context menu for individual cuts. Quick Split Mode helps when you need several cuts, while Mark In and Mark Out points let you select a specific range before placing it on the timeline.

This guide covers each method so you can organize longer recordings, remove unnecessary footage, and prepare clips for further editing on your Mac.

Split a Clip at the Playhead

Select the clip and move the playhead to the frame where the cut should begin. Click the Split button attached to the playhead to divide the footage at that point.

Note: Depending on your timeline selection and editing preferences, splitting may affect multiple tracks. Select the clip you want to divide before using the tool. If the playhead Split button is hidden, go to Wondershare Filmora > Preferences > Editing and enable it.

Split a Clip with the Scissors Tool

For a toolbar-based cut, click the target clip and position the playhead where the two sections should separate. Choose the Scissors icon above the timeline to make the split.

Split a Clip from the Context Menu

You can also Control-click the selected clip, or right-click with a mouse, after placing the playhead at the cut point. Choose Split from the menu to create two sections.

Split a Clip with Quick Split Mode

Quick Split Mode is useful when you need to divide a longer recording at several points. Instead of repositioning the playhead for every cut, you can click directly on the clip while the cutting cursor is active.

Step 1. Open the Timeline Tool Menu

Find the cursor or Select tool control in the toolbar above the timeline. Open its dropdown to view the available editing modes.

Trim a Video Clip

Trimming shortens a clip by excluding footage from its beginning or end. In Filmora for Mac, you can set the range in the preview player or adjust clip boundaries directly on the timeline.

Trim a Clip with Mark In and Mark Out

Use the player to choose the portion of a source clip you want to keep before adding it to your edit.

  • Double-click the clip in Project Media to open it in the preview player.
  • Move to the intended starting frame and choose Mark In (or press I).
  • Find the ending frame and select Mark Out (or press O).
  • Drag the selected range into the timeline to work with that portion of the source video.

Note: You can revise the selected range before adding it to the timeline by adjusting the In and Out positions in the preview player.


Trim a Clip by Dragging Its Timeline Edges

On the timeline, point to the left or right edge of the clip until the trim cursor appears. Drag the edge inward to shorten the beginning or end. Move it outward again if you need to restore some of the source footage.
