AI Video Generator with Sound: Dialogue, Effects and Ambience in One Pass
A silent AI clip is half a shot. Adding the dialogue, the footsteps, the rain and the music afterwards is slow, and it rarely lines up. FloStudio generates each shot with its sound already in it, then gives you one continuous score, narration and subtitles for the finished film.

What sound comes with each shot
Voxmin Video, the model FloStudio renders with, generates picture and audio together, so the sound belongs to what is on screen.
Dialogue
Short lines spoken by the characters in the shot. Keep it to a line or two per shot, one speaker at a time, for the clearest result.
Sound effects
Footsteps, doors, engines, glass: the things you see on screen make the sounds you would expect.
Ambience
Rain, traffic, a busy café, wind. The space of the scene is audible.
Continuity across cuts
The end of one shot’s audio is passed to the next, which helps room tone and atmosphere carry across the cut instead of resetting.
Sound for the whole film
On top of each shot’s own audio, the timeline has tracks for the film as a whole.
One continuous AI score
Compose with AI writes a single track for the full length of the film, with its passages crossfaded, so the music does not restart at every cut. It costs 1 credit per second.
Your own music
Upload a music bed instead, if you have one you are allowed to use.
Narration and subtitles
Turn on narration and subtitles when you export, and choose whether each clip’s own sound is mixed in.
A mixer, not a guess
Separate tracks for clip sound, score and extra audio, with volume and fades on each.
What it cannot do
There is no lip-sync step and no voice cloning: characters speak in voices the model generates, and FloStudio does not copy a real person’s voice. Long speeches do not fit in one shot; split them across shots or use narration.
The model’s supported dialogue languages include English, Spanish, German, French, Italian, Portuguese, Russian, Arabic, Chinese, Japanese and Korean. Hindi is not on that list yet, so a Hindi film is best made with narration or music rather than spoken dialogue.
