Does the product video come with music or sound?

Sound is a choice you make before you generate, next to the length and the shape, and it is frozen onto that film. There are three options. Natural keeps what the model rendered with the shot: the room tone of the set and the small sounds of the product moving. Silent strips the track, so what you download is an MP4 with no audio at all. Voiceover lays a spoken line over the film's own sound, turned down underneath it, or over silence if you switch the bed off.

Composed for the sound-off feed either way

Most of the places these films run start them muted. Reels, TikTok and Meta feeds stay silent until a viewer taps, and many product galleries autoplay without sound. So whichever you pick, the film is shot to sell with the sound off; the sound is for the viewer who taps, and for placements people click to play, like a product page video or an ad.

Writing the voiceover, or letting Nitaris write it

Leave the script empty and Nitaris writes one line from the shot. Type your own and the Studio shows how many words fit: about 26 in ten seconds, and proportionally more in a longer film. Six voices are offered, from an even narrator to a soft, close read, and the voice starts a beat after the first frame so the picture lands first.

Music is still yours to add

Nitaris does not add a music track. Music you did not clear for commercial use is the most common way a product ad gets muted or taken down, so that decision stays with you, in the editor you publish from, where every platform keeps a licensed library one tap away. If you are going to lay music over the film, pick Silent first, so there is nothing of ours to remove.
