What are AI sound effects for video?
A video-to-audio model watches the clip and generates effects, foley and ambience timed to what happens on screen, instead of you placing sounds from a library by hand.
Sound effects for your AI short drama, dialogue untouched
A finished episode with only voices and music sounds empty. DramaSo watches the cut, adds the footsteps, slaps, glass and room tone each shot needs, and lays them under the track you already have. No timeline, no sound library, no re-recording.
Synced to the picture Dialogue untouched Films up to 10 min Beta

Sound is the last 20% that makes it feel finished
Viewers forgive a still frame faster than a silent punch. DramaSo already writes the beats, voices every line and renders the vertical cut; film sound effects close the gap between a dubbed slideshow and an episode that sounds produced, without opening an editor.
Features
Effects that follow the picture
Sound is generated from the video itself, so a door slams when the door slams and the room sounds like the room on screen.
Synced to on-screen action
The engine, Mirelo SFX 2.0 (released 14 October 2026), reads the motion in each shot and times foley and impacts to it.
Consistent across cuts
The whole film is processed in one pass, so the rain in shot 3 is still the same rain in shot 7 instead of restarting at every cut.
Up to 10 minutes per film
Long enough for any vertical episode. A typical 1 to 3 minute short is one click.
Your dialogue stays exactly as recorded
Most video-to-audio tools regenerate the whole soundtrack. DramaSo only asks the model for effects and mixes them under your original track.
Voices are never regenerated
The effects track comes back with speech suppressed. Your dubbed lines and background music are copied from the film as they are, then the effects go on top.
Checked on a real episode
In our 15 October 2026 run, a 32-second, six-line episode came back with effects in under 15 seconds, and a transcript of the mixed film still had all six lines word for word.
Credits back if it fails
The price shows on the button before you run it. If generation fails or times out, the credits are refunded automatically.

Where film sound effects help most
Episodes whose drama lands on a physical moment.
Revenge and slap scenes
The slap, the shattered glass and the gasp of the room land on the frame they belong to.
Stills-only cuts
An episode made of storyboard frames gets room tone and movement, so it stops sounding like a slideshow.
Series with recurring sets
The office, the mansion and the rainy street keep sounding like themselves across every episode.

Quick answers
What does “keep dialogue” mean here?
The generated track contains effects only. DramaSo mixes it under the film's existing audio, so every dubbed line and the music are exactly what you exported.
