For generated campaign clips#
Cinema Director offers optional generated sound. Motion Studio and Scene Replace deliver silent outputs. Audio choices depend on the selected workflow, so check the exact quote before confirming.
- Silent: a video without a soundtrack.
- Generated sound: audio made with the video, when supported. Review what the generator actually produces.
- AI voiceover: narration from your approved wording, when available. Choose the offered voice, currently Marin or Cedar.
- On-screen captions: the short reviewed caption for each scene. These are not automatically timed, word-by-word subtitles.
For uploaded footage in Video Studio#
This Video Studio workflow does not offer new music generation or voice cloning. Do not assume that requesting a song in the prompt gives permission to use it or creates a licensed soundtrack.
| Sound choice | Result |
|---|---|
| Original sound | Use the source audio with the edited footage. Silent sources remain silent. |
| Silent | Deliver without source sound. |
| AI narration + ambience | Read your approved narration and keep original ambience low. |
Review with sound on#
- Read narration before generating: names, pronunciation, claims and timing all matter.
- Keep captions concise and positioned so they do not obscure the subject.
- Listen to the entire finished output, checking speech, pauses, distortion and background levels.
- If the sound needs a new generation or render, review its separate quote.
