Hear what it does

Turn on sound and switch between the clip's own soundtrack and the rebuilt one. The picture never changes. The music goes, the call to the customers stays, and the wok, the flame and the stall come in on the beat.

Music out, wok in

The original has a funk track under his line. The rebuilt sound keeps the line and adds the sizzle, the clang and the flame.

Key features

    Download or keep editing

    Download the result, or open it in the editor and lay your own music on its own track.

Music remover: keep the dialogue

Video models often put music under a scene that nobody asked for. Generating the clip again costs credits and can lose a take you liked, and muting it loses the dialogue too. Rebuild the sound with speech kept, and the lines stay while the music is replaced by sound that fits the picture.

His line stays, now with the breeze and the city below.

What the Mirelo SFX 2.0 SFX generator makes

Foley for action shots

Sneakers squeak, the ball bounces and the rim rattles on the dunk, each on its frame. The sound comes from what the picture shows, with no sound library and no hand syncing.

Ambience that fits the place

Surf, wind and hooves on wet sand for a beach, a long echo for a stone hall. The space on screen sets how the sound behaves, so a scene outdoors never sounds like a room.

One soundtrack for a stitched edit

Three shots generated separately and joined into one sequence. Run the edit at once and the wind and snow carry across every cut instead of jumping between clips.

Impacts on the beat

Each hammer blow, the roar of the fire and the hiss of steam when the metal hits the water. Add one short line when you want a sound to lead, and leave the rest to the picture.

FAQs

What is the Mirelo SFX 2.0 SFX generator?
It turns a video into new sound for that video. Mirelo SFX 2.0 reads the action, timing and setting on screen and builds effects, foley and ambience that land where the action does, while keeping any dialogue in the clip. It handles a full edit of up to 10 minutes in one run.
How do I add sound effects to a video with AI?
Upload the finished video and ask for new sound with the dialogue kept. The video is the main input, so you do not need to list every effect. Add a short line only for a sound the picture cannot show, such as distant thunder.
Can it remove music from a video and keep the voice?
Yes. With speech kept, everything in the soundtrack except the spoken lines is replaced, so music a video model added on its own is gone and the dialogue stays. Add your own licensed track afterwards on its own layer.
How long a video can I run?
Mirelo SFX 2.0 handles up to 10 minutes per run, according to Mirelo. On Morphic today, Sonilo SFX also scores clips up to 10 minutes. Run the whole edit at once so the sound stays the same from shot to shot.
Will the sound match a stitched sequence of AI clips?
Yes, when you run the stitched edit together. Clips generated one at a time each arrive with their own audio, which jumps at every cut. One pass over the assembled sequence gives shots of the same place one continuous sound.
Is the Mirelo SFX 2.0 SFX generator free?
Morphic has a free tier to start. Rebuilding the sound of a video uses video-to-sound models that are available on paid plans.
Can I use Mirelo SFX 2.0 on Morphic?
Mirelo SFX 2.0 is coming to Morphic soon. Until then, Sonilo SFX does the same job: it keeps the dialogue, replaces the music and ambience, and scores clips up to 10 minutes. Every example on this page was made on Morphic with Sonilo SFX; on the music examples, a music bed made on Morphic was added under the dialogue first, to show it being removed.
