Professional assembly timeline built with Swift and AppKit.
Connected clips, B-roll overlays, text lanes, music tracks, and per-clip volume control for desktop editing.
What is Passcut’s assembly timeline?
Passcut features a native assembly timeline built in Swift and AppKit where connected clips stay linked as you trim, split, and reorder — keeping secondary B-roll, text, and music tracks synchronized.
Designed for desktop editors working with complex raw footage, the assembly timeline prevents accidental sync drift when executing prompt-driven rough cuts or manual transcript refinements.
What audio and video lanes are supported?
Passcut includes a primary video assembly track, a B-roll overlay lane for secondary visual cutaways, a text lane for titles, and a music lane, along with per-clip volume controls and full undo and redo history.
Timeline state, cut decisions, transcripts, and media path references are preserved inside .passcut project bundles with automatic background autosave.
