How to Add, Trim, Split, and Delete Clips in Alight Motion (Complete Beginner Guide)
If you’ve just downloaded Alight Motion and stared at the timeline wondering where to even begin you’re not alone. I’ve been there. The first time I opened the app, I accidentally deleted an entire layer and had no idea how to get it back. After months of editing videos, short reels, and motion graphics on Alight Motion, I finally understand every corner of its clip editing system. This guide covers everything: how to add clips, trim them cleanly, split at the right moment, and delete what you don’t need. No beginner mistakes included.
Understanding Clip Editing in Alight Motion
What Are Video Clips in Alight Motion?
In Alight Motion, a video clip is any media file a video, image, or audio that you place on the timeline. Each one sits on its own track, and you can stack multiple tracks on top of each other to build complex edits. Think of the timeline as your editing table, and each clip as a piece of footage you’re arranging in sequence.
Unlike some basic mobile editors, Alight Motion treats each layer independently. That means you can trim one clip without touching another, which gives you much more control over your final output.
Trim vs Split vs Delete vs Crop Key Differences
Before touching anything, it helps to know what each action actually does:
| Action | What It Does |
| Trim | Shortens a clip from the start or end |
| Split | Cuts a clip into two separate pieces at a chosen point |
| Delete | Removes the clip entirely from the timeline |
| Crop | Changes the visible frame area (spatial, not time-based) |
People often confuse trimming and splitting. Trimming works like cutting the edges of a photo you remove from either end. Splitting is like cutting a ribbon in the middle you get two pieces you can work with separately.
Why Clip Editing Matters for Smooth Video Projects?
Rough cuts ruin good footage. Even if your raw video is great, leaving in extra seconds before the action starts or after it ends will make your edit feel sloppy. Clean trimming, smart splitting, and removing unused layers keeps your project organized and your export file tight. Every professional editor even on mobile obsesses over clean timelines.
Before You Start Editing Clips
Alight Motion App and Device Requirements
Alight Motion works on both Android and iOS. For smooth editing:
- Android: Version 5.0 or higher, at least 3GB RAM recommended
- iOS: iPhone 6s or later, iOS 12+
- Storage: Keep at least 1–2GB free for project files and exports
- App version: Always use the latest official version from the Play Store or App Store for best performance
If you’re running an older device, close background apps before editing to prevent lag during playback.
Setting Up Your Project and Timeline
When you open Alight Motion, tap the “+” icon to create a new project. You’ll be asked to choose:
- Frame rate (24fps for cinematic, 30fps for standard, 60fps for smooth motion)
- Resolution (1080×1920 for vertical/reels, 1920×1080 for landscape)
- Duration (you can always adjust this later)
Pick settings that match your final output platform. For Instagram Reels or TikTok, go with 1080×1920 at 30fps. For YouTube, use 1920×1080.
Importing Video Clips into the Timeline
Once your project is open, you’ll see the timeline at the bottom. To bring in your footage, tap the “+” button inside the timeline area, then select “Video” from the media picker. Navigate to your gallery, choose your clip, and it drops straight onto the timeline as a new layer.
Import them one by one. Each clip gets its own dedicated track exactly what you want for organized editing.
How to Add Clips in Alight Motion?
Step 1: Create a New Project
Open Alight Motion and tap the large “+” on the home screen. Name your project something recognizable especially if you’ll have multiple projects open. Set your canvas size and frame rate based on where the video will be published.
Step 2: Import Media Files
Inside your project, look at the bottom panel. Tap “+” in the layers/timeline section. A menu pops up with options like Video, Image, Audio, Text, and Shape. Tap “Video” to browse your device gallery and select the footage you want to work with.
Pro tip: If you need multiple clips, import them one at a time. Each one gets its own dedicated layer, making it much easier to manage later.
Step 3: Add Clips to the Timeline
After selecting a video from your gallery, it automatically appears on the timeline. You’ll see it as a colored bar in the layers panel. The length of the bar represents the clip’s duration. Tap on it once to select it a blue outline or highlight appears around it when it’s active.
Step 4: Arrange Layers and Clip Order
In Alight Motion, elements stack visually the top one in the panel appears on top in the preview. To reorder clips, press and hold it, then drag up or down. For a simple sequence where clip 1 plays before clip 2, place them on separate tracks. Offset their start points so they don’t overlap.
How to Trim Clips in Alight Motion (Step-by-Step)
Trimming is something I use in literally every single project. It’s the first thing I do after importing clean up the start and end before anything else.
Step 1: Select the Clip in Timeline
Tap it in the timeline. You’ll see handles at both ends of the footage bar small vertical lines or arrows on the left and right edges.
Step 2: Adjust Start and End Points
Drag the left handle inward to trim the beginning of the clip. Drag the right handle inward to trim the end. As you drag, the preview window at the top updates in real time so you can see exactly where you’re cutting.
The key here: go slowly. If you overshoot and trim too much, just drag the handle back out nothing is permanently lost until you export. The original footage is always recoverable during editing.
Step 3: Preview the Trimmed Clip
After adjusting, tap play to preview that section. Watch through once fully before moving on. A lot of beginners trim, assume it’s right, and only notice the problem after exporting. One preview save you a lot of time.
Step 4: Save the Changes
Alight Motion automatically saves your trim as you drag. There’s no separate “confirm trim” button your changes apply immediately to the project. Just make sure you tap outside the clip to deselect, and your edit is locked in.
Advanced Trimming Techniques in Alight Motion
Precision Trimming for Frame Accuracy
For frame-level precision, use the timeline zoom feature. Pinch outward on the timeline with two fingers to zoom in this stretches the timeline view so each frame takes up more space. Now when you drag the trim handles, you’re moving frame by frame instead of second by second.
This is essential for sync edits like cutting on a beat drop or matching a visual cue to dialogue.
Trimming Multiple Layers in Sync
If you have several tracks video, audio, text overlay and need them all at the same endpoint, trim each one individually. Use the same position marker as your reference point. Zoom in on the timeline, set your playhead at the exact cut point, and then bring each track’s edge to meet the playhead. This gives you a clean, synchronized cut across all layers.
Trimming Audio and Video Separately
Sometimes your video clip has built-in audio you don’t want or you want to keep the video but swap the audio. In Alight Motion, you can mute the audio on any video track by tapping it and going to its properties, and toggling the audio off. Then add a separate audio layer and trim it independently to match your video timing.
How to Split Clips in Alight Motion?
This tool is my go-to for removing the middle section of a clip. Instead of trimming from the ends, you split at two points and delete what’s between them.
Step 1: Move the Play head to the Split Point
The playhead is the vertical line that moves across your timeline during playback. Drag it manually to the exact moment where you want to split the clip. Use the zoom technique above for precision.
Step 2: Select the Clip Layer
Tap on the clip you want to split in the panel. Make sure it’s highlighted if the wrong track is selected, you’ll split the wrong piece of footage.
Step 3: Use the Split Tool
With your clip selected and the playhead at the right position, look for the scissor/split icon in the editing toolbar. Tap it. The clip instantly breaks into two separate pieces at the playhead position. Both pieces remain on the timeline as separate clips you can now edit independently.
Step 4: Edit Each Segment Separately
Now you have two separate pieces. Move, rearrange, or remove either one. Add a transition between them, apply different effects to each part, or fill the gap with a different clip. This is where creative editing really opens up.
Creative Uses of Splitting Clips
Removing Unwanted Sections
This is the most practical use. Say you recorded a 60-second clip but seconds 20–35 are unusable (you coughed, or the camera shook). Split at second 20, split again at second 35, delete the middle segment, then bring the two remaining pieces together. Clean cut, no one knows.
Creating Highlight Clips
For a sports or event highlight reel, import your long raw footage, then split it at every exciting moment. Delete the boring parts between. What’s left is pure highlight material. This technique alone can turn a 10-minute raw file into a punchy 60-second reel.
Preparing Clips for Effects and Transitions
Splitting lets you apply different effects to different parts of the same original clip. Split at the moment you want a glitch effect to start. Now apply it to just that segment the rest of the footage stays untouched.
Making Short Reels or Social Media Edits
For TikTok or Instagram Reels, you often need to match cuts to music. Import your clip, set your beat markers by ear using the playhead, split at each beat, and rearrange the segments to match the rhythm. This technique is the backbone of that entire workflow.
How to Delete Clips in Alight Motion?
Deleting a Single Clip from the Timeline
Select the clip you want to remove. Then look for the delete or trash icon in the editing menu. It usually appears in the top bar or after long-pressing the clip. Tap it once, and the clip is gone from the timeline.
Important: Deleting from the timeline does not delete the file from your phone. It only removes it from your current project.
Removing Multiple Clips from a Project
Alight Motion doesn’t have a multi-select delete yet you remove them one at a time. Work quickly: select it, delete it, move to the next. Takes under a minute even for 10+ layers.
Cleaning Up Unused Layers
One habit that separates organized editors from messy ones: scroll through your timeline before exporting. Remove any empty tracks, placeholder clips, or audio stubs you no longer need. Unused tracks don’t affect your video output, but they slow down performance and make the timeline confusing. Keep it clean.
Pro Tips for Better Clip Editing in Alight Motion
Keep Video Quality High After Trimming
Both actions are non-destructive in Alight Motion during editing your original file stays untouched. The quality hit happens at export. To keep quality high:
- Export at the same resolution you imported
- Set bitrate to High or Maximum in export settings
- Use MP4 (H.264) for best compatibility without major quality loss
Use the Timeline Zoom for Precise Editing
I mentioned this above, but it’s worth repeating: pinch-zoom on the timeline is the single most underused feature by beginners. Once you zoom in, your precision goes from “roughly right” to frame-perfect. For any sync edit, music video, or beat-matched reel always zoom in first.
Organize Layers for Faster Workflow
Name your tracks if the app version allows it. Group related clips together. Keep your video tracks at the bottom, audio in the middle, and text/effects on top. A 5-minute habit of organizing before you start saves 20 minutes of confusion halfway through a complex project.
Common Mistakes to Avoid When Editing Clips
Accidentally Trimming Important Footage
This happens when you’re in a rush. You drag the trim handle quickly and overshoot. Always preview immediately after trimming. If you caught it in time, drag the handle back out. If you already exported that footage is gone from the output but still intact in the project file, so you can re-export.
Misplacing the Play head While Splitting
If your playhead is even one frame off, your split will be off too. In music-synced edits, one frame feels very wrong. Always zoom in before splitting. Always.
Deleting Clips Without Backup
Before doing any major restructuring of your timeline, export a draft version of your current edit. This takes 2 minutes and gives you a safety net. I learned this the hard way after accidentally clearing a layer I’d spent an hour color-grading.
Troubleshooting Clip Editing Issues in Alight Motion
Clip Not Splitting or Trimming
Most common cause: The layer is locked. Look for a lock icon next to the item in the panel. Tap it to unlock before trying to edit. If there’s no lock icon, make sure you’ve actually selected the layer (it should be highlighted).
Layer Lock Problems
Go to the panel, find the padlock icon on that element, and tap it to toggle the lock off. Locked items are read-only no trimming, splitting, or moving until unlocked.
Tool Selection Errors
If tapping the split or trim area isn’t working as expected, check your active tool. You may have accidentally switched to the transform or move mode. Look at which tool is currently active in the toolbar and switch back to the selection tool first.
App Lag or Performance Issues
Long projects with many layers can get sluggish. Try these fixes:
- Close all background apps on your phone
- Lower the preview resolution in Alight Motion’s settings (this doesn’t affect export quality)
- Break very long projects into shorter segments and combine them at the end
- If lag persists, restart the app it clears cached preview data

Why Editors Prefer Alight Motion?
Most basic mobile editors give you one video track. Alight Motion gives you unlimited layers video, audio, shapes, text, effects all stack able and independently editable. For anyone serious about mobile editing, especially motion graphics and sync edits, nothing on mobile comes close to this level of control. The learning curve is steeper, but what you can produce is in a completely different league.
Quick Workflow: Edit Clips in Alight Motion in Minutes
If you want the fastest possible workflow without going through every detail above, here’s your cheat sheet:
Add Clips
Tap “+” in the timeline → Select “Video” → Choose from gallery → Done.
Trim
Tap clip → Drag left/right handles inward → Preview → Done.
Split Clips
Move playhead to split point → Tap clip → Tap scissor icon → Done.
Delete Unwanted Clips
Tap clip → Tap trash/delete icon → Done.
That’s the entire core workflow. Everything else precision zooming, multi-layer sync, audio separation builds on these four actions.
Conclusion
Clip editing in Alight Motion isn’t complicated once you understand what each tool does and why. Adding clips builds your foundation. Trimming cleans up the rough edges. Splitting gives you creative control over every moment in your footage. Deleting removes what doesn’t belong.
The difference between an average edit and a polished one usually comes down to these basics done carefully, with good habits. Use the timeline zoom, preview before you commit, and keep your layers organized. Once these four actions become second nature, everything else in Alight Motion gets easier.
Start with one clip today. Shorten it. Cut it in half. See how it feels. That’s how every editor beginner or pro actually learns.
