Clips and the editor
The editor: B-roll, music and SFX
Three tiles in the editor add layers on top of the talking head: B-roll for footage and images, Music for a bed under the voice, and SFX for hits, whooshes and stings. Each is placed on the timeline and baked into the final MP4.

Add B-roll
Click the B-roll tile. Auto b-roll sources stock video for the clip at a density of Light (2 clips), Medium (3 clips) or Heavy (4 clips) — press Add. Or pick by hand from the tabs: AI (suggestions), Search (images), Pexels (video), GIFs, Uploads and Generate, which makes an image from a description.

Choose a music bed
Click the Music tile. Library lists curated stock tracks; Search looks up Pixabay; Uploads takes your own audio file; AI proposes a track for this clip; and the mood picker under Library generates a fresh track to match the mood when the video is generated. A track and a mood are exclusive — picking one clears the other.

Add sound effects
Click the SFX tile and press Auto-generate sounds. It reads the clip you already have — the hook, the cutaways, the pauses in what you say and the numbers you quote — and places sounds on those moments, matched to the caption style you picked: impacts for a Bold Yellow or Big & Loud clip, softer air for Documentary or Minimal. It is instant and costs nothing. Every sound it places is marked auto, and Regenerate sounds replaces only those, never one you added or moved yourself. To place one by hand instead, the library below is grouped as Whoosh, Impact, UI, Comedy and Transition: Preview to hear it, then add it, and drag its marker on the timeline to move it.

Check the timeline and generate
Every layer appears as a pill on its own row of the timeline, where you drag it to a new time or remove it. When the header reads Saved, press Generate video.

Good to know
- The Music panel is not pictured: opening it asks the AI for a mood suggestion, which we do not run for a screenshot.
- Uploaded B-roll and audio stay in your library for other clips.
- Auto-generate sounds after you have added your b-roll, not before — it places a whoosh on every cutaway, so it has more to work with once the footage is there.
