Video with sound
Which models generate sound out of the box and how to add sound to a silent clip.
There is no separate sound switch in the form — sound is a property of the model. Some models produce a clip with sound right away, others without.

How to add sound to a finished clip
- “Sound for video” — the model picks noises and effects for your clip; you can describe the sound you want in words.
- “Audio merge” — lays a ready track from your generations (voice-over or music) over the clip, with an offset of up to 60 seconds.
Under a finished video there are next-step buttons that take you straight to adding sound.
