\nBut once you grasp how layers and compositions work? It all clicks. You\u2019ll be able to cut, trim, split, and isolate exactly what you need\u2014no broken timelines, no lost sync, just smooth edits.
\nBelow is a beginner-friendly, step-by-step guide to cutting clips in After Effects\u2014written like a friend walking you through it. We\u2019ll cover every technique, shortcut, and common pitfall along the way.
\nStep 1: First, learn how layers and the timeline actually work
\nBefore you make a single cut, let\u2019s clear up a key difference: After Effects doesn\u2019t use traditional video tracks. Instead, everything lives in layers inside a composition\u2014think more like Photoshop\u2019s layer system than Premiere Pro\u2019s track-based setup.
\nEvery video or image you drag into the timeline becomes its own layer. These layers can overlap in time (so one plays over another) or stack visually (so one sits on top of another).
\nThat means when you \u201ccut\u201d in After Effects, you\u2019re not slicing through multiple tracks at once. You\u2019re trimming or splitting individual layers\u2014a small shift, but one that changes how you edit.
\nStep 2: Use the split shortcut to cut a layer at the playhead
\nThis is the most direct way to \u201ccut\u201d a clip in After Effects\u2014it splits a single layer into two separate pieces. Here\u2019s how:
\n1.Click the layer you want to cut to select it (make sure it\u2019s highlighted in the timeline).
\n2.Move the time indicator (the small, movable playhead) to the exact spot where you want the cut to happen.
\n3.Press the shortcut: Mac: Shift + D
\na.Windows: Ctrl + Shift + D

\nYour clip will now split into two layers: one that ends at the playhead, and another that starts right after it. You can delete, move, or adjust each piece independently\u2014no effect on other layers.
\nNote: This is \u201csplitting\u201d a clip, not \u201ctrimming\u201d (we\u2019ll cover trimming next).
\nStep 3: Trim clips with in and out points
\nSometimes you don\u2019t need to split a clip\u2014you just want it to start later or end earlier. That\u2019s where trimming comes in: it lets you \u201chide\u201d parts of a layer without splitting it. Here\u2019s how to do it quickly:
\n1.Move the playhead to where you want the clip to start.
\n2.Set a new in point (the clip\u2019s starting point): Mac: Press [ (left bracket key)
\na.Windows: Press Alt + [
\n3.Move the playhead to where you want the clip to end.
\n4.Set a new out point (the clip\u2019s ending point): Mac: Press ] (right bracket key)
\na.Windows: Press Alt + ]

\nAfter Effects will now only play the portion of the layer between your in and out points\u2014even though the full file is still saved (so you can undo the trim later if you want).
\nYou can also trim by dragging the edges of a layer in the timeline, but shortcuts are way faster once you get used to them.
\nPro tip for Premiere users: If you miss using single keys (like C for the razor tool) to edit, you can customize After Effects\u2019 shortcuts! Go to Edit > Keyboard Shortcuts and remap trim\/split commands to match your Premiere workflow\u2014no more retraining your muscle memory.
\nStep 4: Pre-compose to cut inside a nested composition
\nWhat if you have a complex animation (say, text + shapes + effects) and want to trim part of it without messing up your main timeline? That\u2019s where pre-composing (or \u201cnesting\u201d) comes in. It groups layers into a single \u201cmini-composition\u201d you can edit separately. Here\u2019s how:
\n1.Select all the layers you want to group (click and drag, or hold Shift to select multiple).
\n2.Create a pre-comp: Right-click the selected layers and choose Pre-compose, or
\na.Use the shortcut: Windows (Ctrl + Shift + C) \/ Mac (Shift + C).
\n3.Open the new pre-comp (it will show up in your Project panel). Inside it, you can trim, split, or edit layers as much as you want\u2014no effect on your main composition.
\n4.Go back to your main timeline: the pre-comp now acts like a single layer. You can move it, trim it, or add effects to it without opening the nested comp.
\nPre-comps are a game-changer because they\u2019re non-destructive (you can always edit the layers inside later) and keep your main timeline clean. Here\u2019s why they\u2019re useful:
\n\u25cfIsolate cuts or effects so you don\u2019t break other parts of your project.
\n\u25cfReuse the same pre-comp in other compositions (great for consistent elements like logos).
\n\u25cfKeep complex setups organized (no more scrolling through 20 layers to find what you need).
\nStep 5: Cutting and trimming audio layers
\nGood news: Cutting audio works exactly like cutting video\u2014same shortcuts, same process.
\n\u25cfTo split an audio layer: Use Shift + D (Mac) \/ Ctrl + Shift + D (Windows) at the playhead.
\n\u25cfTo trim audio (set in\/out points): Use [\/Alt + [ (start) and ]\/Alt + ] (end).
\nOne common gotcha: You won\u2019t hear audio if you just scrub the timeline (drag the playhead back and forth). To preview audio, press 0 on your numpad\u2014that triggers a RAM preview with sound.
\nStep 6: When to use Premiere Pro instead (yes, really)
\nAfter Effects is powerful, but it\u2019s not the best tool for every job. If you\u2019re editing a full video with tons of clips\u2014like a vlog with scene changes, interview cuts, or audio syncing\u2014do your base edit in Premiere Pro first.
\nSave After Effects for what it\u2019s best at: motion graphics (like animated text), compositing (layering visuals), or sprucing up specific shots (like adding effects). Then, bring your AE work back into Premiere using:
\n\u25cfDynamic Link: Edits you make in AE update automatically in Premiere (no re-exporting!).
\n\u25cfRendered clips: Export your AE composition as a video file and drag it into Premiere.
\nFrequently Asked Questions (FAQs)
\nQ: How do I cut a part of a clip in Adobe After Effects?
\nMove the playhead to where you want the cut, select the layer, then press Shift + D (Mac) or Ctrl + Shift + D (Windows). This splits the layer into two separate pieces you can edit independently.
\nQ: What\u2019s the shortcut to split a clip in After Effects?
\n\u25cfMac: Shift + D
\n\u25cfWindows: Ctrl + Shift + D
\n Just make sure a layer is selected\u2014if no layer is highlighted, the shortcut won\u2019t work.
\nQ: Why can\u2019t I cut clips in After Effects?
\nThe most common issues are:
\n1.No layer is selected (click the layer in the timeline first).
\n2.You\u2019re in the wrong panel (e.g., the Project panel instead of the Timeline panel).
\n3.Your shortcut is overridden (check Edit > Keyboard Shortcuts to fix it).
\nQ: How do I \u201ccut out\u201d part of a clip in After Effects?
\nIt depends on what you mean:
\n\u25cfCut time: Split the layer at the playhead with Shift + D (Mac) \/ Ctrl + Shift + D (Windows).
\n\u25cfTrim the visible part: Use [\/Alt + [ (start) and ]\/Alt + ] (end) to hide parts of the layer without splitting it.
\n\u25cfCut out a visual part (e.g., remove a person from a frame): Use a mask (with the Rectangle Tool or Pen Tool) to isolate the area you want to keep.
\nQ: Can I use the razor tool like in Premiere Pro?
\nAfter Effects doesn\u2019t have a dedicated razor tool\u2014but you can replicate it! Use the split shortcut (Shift + D\/Ctrl + Shift + D) to cut layers. If you want it to feel like Premiere, go to Edit > Keyboard Shortcuts and remap the split command to C (the old Premiere razor tool key).
\nQ: How do I trim multiple clips at once?
\nSelect all the layers you want to trim (hold Shift and click each one), then use the trim shortcuts: [\/Alt + [ (set in points) or ]\/Alt + ] (set out points). All selected layers will trim to the playhead.
\nQ: What if I want to undo a cut or trim?
\nJust press Cmd + Z (Mac) or Ctrl + Z (Windows). After Effects treats every split or trim as an undoable action\u2014same as any other edit.<\/p>\n","protected":false},"excerpt":{"rendered":"
