Adding music to Alight Motion transforms a simple edit into a polished video with mood, rhythm, and impact. This guide walks you through reliable ways to import, trim, and sync audio so your projects sound professional.
Whether you are scoring a slideshow, a kinetic title sequence, or a fast-cut montage, Alight Motion gives you precise control over timing, volume, and effects. The steps below are designed for beginners and experienced editors alike.
| Task | Where in Alight Motion | Quick Tip | Common Issue |
|---|---|---|---|
| Import audio file | Media Library > Add Media | Use MP3 or WAV under 10 MB for best performance | File not showing up if unsupported format |
| Trim audio to clip | Audio track timeline > Handles at edges | Zoom in for frame-accurate cuts | Cutting removes part of the waveform accidentally |
| Adjust volume over time | Audio track > Keyframe diamonds | Add keyframes before loud transitions | Sudden volume jumps sound unnatural |
| Fade in or fade out | Opacity keyframes at clip starts or ends | Use 20–50 ms fades for smooth edits | Forgot to extend audio under video |
| Sync to beats | Playback + zoomed waveform + markers | Tap screen on beat peaks | Marker count drifts over long timelines |
Keyword-Specific Topic: Import and Basic Setup
Getting music into Alight Motion starts before you open the editor. Prepare your files, understand project settings, and choose the right audio track layout.
First, save your music in a common format such as MP3 or WAV and keep the file size manageable. Place the file where you can easily find it, such as your phone’s Downloads or a dedicated Media folder.
Within Alight Motion, create a new project with a resolution that matches your final export, like 1080x1920 for vertical social videos. Then use the Media Library import button to add the track and drag it onto the Audio track above your video layer.
Keyword-Specific Topic: Trimming and Timing
Trimming music in Alight Motion lets you align the beat with key visual moments and remove unnecessary silence.
Tap the audio clip on the timeline and drag the edges to shorten the duration. Use the magnifying glass to zoom into the waveform so you can cut precisely at the exact frame where the music hits.
When you need the music to end exactly with the final action, line up the clip handle with the last frame of video and add an out point. This prevents awkward cuts or abrupt stops.
Keyword-Specific Topic: Volume Keyframing and Effects
Keyframing volume helps music sit well under voiceovers, sound effects, and transitions without overwhelming your message.
On the audio track, add keyframe diamonds at points where the music meets dialogue or SFX. Lower the volume at those moments and raise it again when the voiceover pauses.
Alight Motion also supports basic fade handles and opacity keyframes. Use short fades instead of hard cuts to keep the audio smooth and professional.
Keyword-Specific Topic: Syncing to Visuals and Beats
Syncing music to visuals turns random cuts into a rhythmic sequence that feels intentional and energetic.
Enable the beat marker tool or tap the screen manually when the song hits a strong downbeat. These markers act as checkpoints so your edits match the musical phrasing.
For complex edits, split long music tracks into shorter segments and align each piece to a different visual beat. This keeps energy high and avoids holding on one single section too long.
Final Keyword-Specific Topic: Best Practices and Next Steps
Applying consistent workflows and simple organization habits makes adding music to Alight Motion faster and more reliable over time.
- Import high-quality MP3 or WAV files to preserve clarity on different devices.
- Use markers to tag beats and sync points before you start cutting.
- Create keyframes for volume, fades, and ducking around dialogue.
- Name your audio layers to keep complex projects easy to navigate.
- Test the final export on both headphones and speakers to catch balance issues.
FAQ
Reader questions
Why does my imported music sound distorted or quiet?
Check the audio levels on the track; lower the clip gain if the peaks are clipping, and avoid stacking multiple loud music layers on top of each other.
Can I use a music track longer than my video project?
Yes, shorten the audio on the timeline so it matches the video duration, or trim sections you do not need and delete the unused remainder.
How do I make the music fade out smoothly at the end of the video?
Add an opacity keyframe near the final frames, gradually lower the volume to zero, and keep the transition under 50 milliseconds for a clean fade.
What should I do if the audio and video get out of sync after editing?
Ripple delete gaps on the timeline, avoid pulling clips in a way that shifts the audio layer separately, and double-check zoomed waveforms for alignment.
