Rebuilding the UX of a Browser Video Editor: Removing Friction

Description and use

By shifting focus from technical capability to user expectation, the editor's usability improved significantly. The project gained traction (500+ GitHub stars) by resolving small but critical friction points in interaction design, gesture handling, and layout logic.

Problem

The initial version of Timeline Studio, a local-first browser video editor, had functional features but a clunky, unintuitive user experience. Users faced friction in basic interactions like splitting clips, scrolling, and managing audio tracks, leading to feedback that the interface was hard to use despite having many features.

Outcome

Workflow

Analyze user feedback to identify friction points in existing features.
Refactor split logic to default to the clip under the playhead if no clip is explicitly selected.
Implement gesture locking for wheel events to prevent mode switching during continuous scrolling or zooming.
Scope audio separation actions to the specific timeline clip rather than the shared source asset ID.
Update auto-layout algorithms to preserve the position of existing clips when adding new audio/voice tracks.
Pin the main visual track below the timeline ruler to keep it in view during vertical scrolling.
Redesign mobile layout to prioritize preview and timeline, using a bottom drawer for properties and touch-sized controls.
Fix minor UI inconsistencies such as export popover toggling, tooltips, and locked track visual indicators.

Evidence

The project has since passed 500 GitHub stars. The number is nice, but the more meaningful milestone was going back and fixing the small frustrations that made the entire editor feel harder than it needed to be.

Source

The editor started becoming a product when the question changed to: 'What does the user reasonably expect to happen here?'
