FEATURE · TIMELINE
A video timeline built for audio layers
Keep music, voiceover, SFX, subtitles, and original video audio on separate lanes, then mix them together before export.
Audio needs more than one track
Short videos often have several audio layers: original camera audio, background music, narration, sound effects, and sometimes captions or timing markers. When all of that is treated like one background track, the mix gets messy.
Fuse uses a multi-lane timeline so each source has its own place. You can adjust music without touching voiceover, mute original audio without removing SFX, or preview only the speech before exporting.
What you can control
- Separate lanes for music, voiceover, SFX, original audio, and subtitles.
- Per-lane volume controls.
- Mute and solo for checking the mix.
- Clip trimming and positioning.
- Fade-in and fade-out.
- Auto-duck routing for music under speech.
- Timeline preview before export.
Why it matters
A clean short-form video is not just about the picture. Music should support the cut, voice should stay clear, SFX should hit on time, and subtitles should match the spoken rhythm.
The timeline gives each part of that audio pass its own layer, so the final export sounds intentional instead of stacked together at the last second.

FAQ
What does "multi-lane timeline" mean?
It means different audio sources live on different lanes. Music, voiceover, SFX, and original video audio can be edited and mixed separately before they become one final export.
How is this different from a basic video editor timeline?
A basic editor may let you place audio under a video, but the controls are often clip-by-clip. Fuse is built around the audio pass: separate lanes, mute/solo, fades, volume controls, and auto-duck for speech-heavy videos.
How many lanes can I have?
Most short-form projects use a few lanes: video audio, music, voiceover, SFX, and subtitles. Practical limits depend on browser performance and project size.
Does the timeline work on mobile?
Fuse is currently optimized for desktop browser resolutions, where the timeline, audio lanes, and export workflow are easiest to control. Mobile browser support is planned for upcoming updates, so creators will be able to make quick edits from a phone later. For now, use Fuse on a desktop or laptop for the full editing experience.
Mix the audio before you export.
Upload a clip, place each audio source on its own lane, and finish the video with a cleaner mix.
