Who this helps: Creators and small-business owners
Bring: Original clips, approved words, intended output and fidelity requirements.
Follow the workflow
- If you already have talking footage, begin by editing synchronized original segments. A transcript-oriented editor can help locate words, but review the actual video.
- For changed words, rerecord or cover approved narration with relevant original footage. Consider dedicated lip-sync only after reviewing authorization and testing the result.
- Use generated motion for a clearly illustrative scene only when its potential visual changes and cost are acceptable. It must not stand in as proof of a real experience.
- Watch the full export frame by frame around difficult cuts, then at normal speed. Check captions, audio continuity and altered visual details. Keep the original project and source footage.
Worked example · illustrative, not a reported result
Fictional edit: remove a repeated introduction from both tracks. Add a newly recorded correction over a real detail shot. Do not generate a different product opening its lid and present it as your demonstration.
Prompt to adapt
Replace placeholders with approved facts. Copy or download locally, then paste into your chosen tool yourself. No automatic import occurs.
Before you move on
- Speech and lips match?
- No documentary claim from generated imagery?
- Actual export checked?
Common problem and recovery
A model can produce plausible motion while changing the object. For exact items, use a conventional pan/zoom or record the action.
