THE EDIT / UPDATED OCTOBER 4, 2026
Add sound to a Hotel Lobby AI video
Treat image generation and music editing as separate steps. A soundtrack can support the rhythm of a performance without being exact lip sync.
- Inspect the downloaded clip. Listen for existing sound. Decide whether to keep it, mute it or lower its volume before adding another track.
- Choose permitted audio. Use your own recording or a track whose terms cover your intended publication.
- Trim a useful segment. In the audio desk, choose a start time and a five- or fifteen-second length. Preview and download the WAV.
- Align in a video editor. Place the WAV under your video. Shift the audio so a strong beat coincides with an obvious gesture or cut. Listen for abrupt starts and endings.
- Export and check again. Open the finished video outside the editor. Confirm that it plays with sound and that the end is not cut off. Review your platform’s music rules before publishing.
Try a complete trimming example
Our audio case includes an original demonstration beat, the selected 1.50–6.50-second interval and a downloadable 5-second WAV. It demonstrates the local tool, not a finished video edit.
If the mouth does not match
Moving the soundtrack may improve a moment, but it cannot turn arbitrary generated mouth motion into accurate words. Exact speech or singing alignment requires a workflow designed for that audio, followed by a result check. This tool does not perform that processing.
Before paying for another render
Check the generator’s actual inputs: photos, audio, motion reference and duration. A photo-only prompt workflow cannot be assumed to copy a particular recording’s choreography. Keep the first test short and review faces, hands, shared framing and sound before making longer clips.
