Put a voiceover or a song in a video

How you put a voiceover or a song in a video depends on what you want the sound to do: play under your clips as it is, be the narration of a story, or be the voice a clip speaks in.

Under your clips, as it is

A finish card on a Creative Board cuts clips together and plays a voiceover or a song under them.

1. Get the sound onto the board. Make it there on a Voiceover or Music card, or open a voiceover or song in your Library and press Add to a board.
2. Add a Finish card from the board's Add a card menu.
3. Wire in the clips to its Clips port, up to 8. They play in the order you wire them, up to 60 seconds in all.
4. Wire the voiceover or song into its Audio port. A finish takes one.
5. Wire in the words, if you want captions, into its Script port. Captions are timed to the voiceover's words.
6. Run it. The price is on Run before you press.

How the sound is mixed:

• A voiceover leads. It plays at full level, and the clips' own sound sits well under it, quieter still while the voice speaks. If the voiceover runs longer than the clips, the last frame holds until it ends. A finish takes a voiceover of up to 60 seconds.
• A song sits under the clips. Their own sound leads, such as a presenter's voice, and the song dips whenever someone talks, repeats if it's shorter than the cut, and fades out at the end.
• A clip's sound can go on the Audio port too, and plays as a voiceover would.

As the narration of a story

On Story, a script becomes a narrated motion-graphics video. To narrate it with your own voiceover instead of an AI narrator, open the Voice chip, choose My own recording, and add a voiceover you made or a file. Every word of the script is timed to it, and you pay for the render alone.

As a voice the clip speaks in

On Video, a model that takes Audio refs works from a recording you give it, and your prompt says what it is for: on Seedance, a voice to speak in, a song under the clip or a sound effect. Add your voiceover or song to the Audio refs slot, name it in the prompt as @Audio1 and say how to use it. The model makes the clip's sound, using yours as its reference, so to be sure the voiceover or song plays exactly as you made it, use a finish card instead. To keep the model from adding music of its own, turn off the Music switch beside Sound.

On a board, the same goes for a voiceover card, a music card or a clip's sound dropped on a clip card's Audio refs port.

Lip-synced to your voiceover

On a board, pick a talking model on a video card (only a talking model shows a Voiceover port), then wire the voiceover into its Voiceover port and a picture of the face into its Start frame: the face says your voiceover, lip-synced, and the clip is as long as it is. To match a clip you already have to new words, set a video card to Lip-sync it. See Sound in your video: voices and lip-sync.

In your own editor

Download the voiceover from Voice, the song from Music, or either from your Library, and the clips from Video, and put them together in any editor. To find stock cutaways for the moments in a voiceover or song, use Match to audio on B-Roll: see Find B-roll for your edit.
