Every video is narrated from a script Velo writes for you. You review it in the chat, before or after the video generates, and the same controls apply no matter which path you started from.

​
Where you edit the script

Edit script in the preview panel on the right is available on every path, whichever way you started. It lists the narration against the timestamps it lands on, and it is where the controls live.

If you only learn one place to change a script, learn this one — it works everywhere.

​
Scene cards

Three paths also show the script as scene cards in the conversation, because Velo is building the visuals as well as the narration: Screen recordings and uploaded videos do not get scene cards — Velo already has the visuals, so there are no scenes to plan.

Each card carries: Scene cards are a planning view — they show what Velo intends to build. The Edit script panel remains available on these paths too, and is still where you regenerate the voice.

​
Changing the script

Three controls sit under the script itself: AI Rewrite is also in the Quick actions menu below the conversation, alongside Disable Zooms, Add Music, Add Logo, Add Face, Change Voice, Publish video, and Open full editor.

You can also just say what you want in the chat — “make the intro shorter”, “say Hi Sam at the start” — and Velo rewrites from there.
Voice generations are metered per video. The panel shows how many you have left, and switches to Free limit reached — upgrade to continue once they are used. See Plans & billing.

​
Persona and audience

AI Rewrite asks two questions before rewriting: which persona the voice should carry (Founder, Marketer, Designer, Sales person, Marketing Strategist, Product Manager, Engineering, Customer Support, Data Analyst) and who the audience is. Both are shown as chips under the preview once set, and you can skip either.

​
Editing in the full editor

For finer control, select Open full editor from Quick actions and use the Scripts panel in the right-hand sidebar. It carries the same Generate Voice and AI Rewrite controls.

​
What happens next

Once the script reads the way you want, select Generate voice. Velo re-renders the narration and updates the preview. Until then the video keeps the audio it already had.
