Its extensive range of features and tools and astounding editing capabilities make it an irreplaceable asset in the arsenal of every professional designer and video editor looking to create visually striking, top-grade, shareable online content. After Effects trims and splits clips, allowing you to extract and edit specific segments of the original video separately. Let's delve deeper into the best ways to cut a video in After Effects.

Different Methods for Cutting Clips in After Effects

After Effects offers different methods for cutting videos that can come in handy when you wish to remove unwanted segments of your footage or clip the length of the original video. Since Adobe Effects doesn't have a traditional Cut feature, you can cut videos by splitting layers, duplicating layers, trimming video segments, and more.

Thanks to that, you can edit each layer, adjust pacing and timing, apply different effects to specific footage segments, and more. Below, we've listed the top 5 options to cut a clip in After Effects.

Method 1: Using the Split Layer

Split Layer is a feature in After Effects that allows you to transform your video into two separate clips, each conveniently placed in an editable layer.

Step 1: Launch After Effects and select New Composition from the menu to open a new project. Navigate to the Composition Settings window, name your project, adjust width/height, select aspect ratio, pick your frame rate, and click OK to create a new project.

Step 2: Navigate to File - Import - File and upload your video. Drag it to the timeline and zoom in on the timeline to make your clip easier to edit.

Step 4: Now, you have two clips in separate editable tracks on the timeline. You can edit both tracks separately and add transitions, effects, etc.

Method 2: Using the Duplicate Layer

Step 1: Position the timeline indicator to where you want to cut your imported clip.

Step 2: Navigate to Edit - Duplicate

After that, hover over the start or end of the clip to access the Trim icon. Drag your clip to the frame you want to cut down to.

Additionally, you can position your timeline indicator to the exact scene where you want to cut your video and hold Shift while trimming the layer to move to the position of the timeline indicator automatically. Delete unwanted parts and export your footage.

Method 3: Using Shortcuts

After Effects allows you to cut videos faster using keyboard shortcuts. Below, we'll list the shortcuts you can use to trim, split, and cut your videos in After Effects on Windows and Mac:

  • Duplicate the clip: Command+D (Mac) / Ctrl+D (Windows).
  • Create a Split Layer: Command+Shift+D (Mac) / Ctrl+Shift+D (Windows).
  • Trim the clip: Option+[ (Mac) / Alt+[ (Windows) to trim the start; use Option+] (Mac) / Alt+] (Windows) to trim the end.

Step 1: Position the playhead to the exact position where you wish to cut the video and click the clip to select it.

Step 2: Press Option + [ on Mac or Alt + [ on Windows to automatically trim the selected clip from the beginning. Change the open brackets to closed brackets to do the same from the end of the clip. After Effects will instantly cut your original video to a shorter clip.

Method 4: Using In and Out Points

In and Out points is a function in After Effects that allows you to swiftly trim your video duration and shorten a long clip according to your specific needs. These points instruct After Effects to only play the clip between the specified points in the timeline, also called In and Out points. You can access them using B (In Point) and N (Out Point) keys on your keyboard.

Step 1: Position the timeline indicator where you want to set your In Point and hit the B key to establish the starting point.

Step 2: Move the indicator to the endpoint and hit the N key to set the Out Point. Afterward, you can place your clip into the render queue to export and save it on your computer.

Method 5: Using Trim Comp to Work Area

The Trim Comp to Work Area function in After Effects allows you to trim multiple clips simultaneously. Instead of editing each layer separately, you can trim all video tracks in a batch.

Step 1: Launch After Effects and import your video clip. Drag the clip to the Project panel to create a new composition.

Step 2: Drag the indicators to the positions of the Start and End of Work Area where you want to make changes.

Step 3: Navigate to Composition - Trim Comp to Work Area to cut the composition to the starting and ending points of the specified Work Area. Preview your changes and export your clip.
