One-click Generate on the timeline lanes
Every timeline lane carries a ✨ — Titles, Captions, Music and VO, plus motion graphics and sound effects — with style, mood and tempo pickers for music.
The timeline's extra lanes — Titles, Captions, Music and VO, plus MG (motion graphics) and SFX (sound effects) — don't make you compose a prompt from scratch. Every lane has a ✨ on its left rail. When a lane is empty and you have edit access, it can also show a ghost button in the lane: Generate titles and Generate captions (in Chat mode), Generate music, Generate voice-over. For motion graphics and sound effects, see Generate with Eddie.
Titles and captions
Click the button and a small composer opens with a ready-made ask ("Add titles to this edit." / "Add animated captions to this edit.") already selected — tweak it or send it as is. Eddie does the rest, same as if you'd typed it into Prompt Eddie.
Music: style, mood, tempo
The Music composer adds three dropdowns — Style (cinematic, ambient, acoustic, electronic, lo-fi, hip-hop, rock, pop, jazz, classical), Mood (uplifting, calm, hopeful, dramatic, energetic, melancholic, playful, tense) and Tempo (slow, mid-tempo, fast) — plus a free-text line for instrumentation and how the track should build. Every choice lands verbatim in the prompt; leave them all on "Any" and Eddie matches the track to the edit's content. The result is a freshly generated track. To place a track you've uploaded, click Add cue on the empty lane (or + on its rail) and choose From the shelf or Upload a file — see the music shelf.
Voice-over (and dubbing)
The VO lane's composer goes further: describe what you want and let Eddie draft the script (free) before you generate, preview the voices, set where the clip lands — or switch on Dub this edit to translate the dialogue into another language.
How it's billed
The titles, captions and music buttons dispatch a normal Prompt Eddie run — Eddie picks the right tool and the run is charged like any other prompt (generation costs, like AI music, are the same as when you ask in chat). The voice-over composer generates directly: drafting a script is free, and you pay only the voice-over rate when you click Generate. The button guards against double-clicks, so an impatient second press can't fire a second paid run.
Viewers and commenters see a plain hint instead of the button — generating needs edit access.
