Timeline

#Tracks

• Captions shows the word-level narration captions.
• Graphics shows full-canvas graphic beats and overlay graphics playing on top of footage.
• Media shows every visual clip: video in blue, images in green.
• VO represents the narration track.
• Music represents the background score track.

#Trimming and snapping

Drag either edge of a clip to trim it. Clips never overlap, so to give one more room, shorten its neighbour first. Snapping magnetizes edges to the nearest boundary; the SNAP toggle next to CC turns it off for free trimming. Overlay graphics on the Graphics track trim independently of the clip they play over.

#Zoom and history

Undo and redo sit beside the timeline zoom control, along with a reset button that restores the timeline to its original build (with confirmation, and itself undoable). Zoom with the slider, a trackpad pinch, or a vertical scroll over the timeline, and the zoom stays anchored under your cursor.
