Features

Mirelo SFX v1.5 (Video-to-Sound)

Mirelo SFX v1.5 turns your videos into synchronized sound effects using advanced multimodal AI. It listens, sees, and imagines — automatically generating realistic or cinematic sound layers that perfectly match the visual rhythm. Whether it’s footsteps, explosions, or ambient noise, this model brings motion to life.

Why it sounds great

• AI-driven sound synthesis – Generates sound effects that fit object motion, timing, and energy directly from video frames.
• Cinematic awareness – Detects on-screen actions (impacts, motion, intensity) and produces corresponding effects.
• Multiple variations – Create multiple versions of the same video for creative control and sound design diversity.
• High coherence – Outputs seamlessly loopable audio segments aligned to scene transitions.
• Plug-and-play – Just upload a video clip, set samples, and receive ready-to-use sound effects.

Limits and Performance

• Max duration per job: up to 10 seconds (minimum billing covers 5 seconds)
• Processing speed: typically 6–12 seconds per generation
• Input: MP4, MOV, or URL video upload
• Output: AI-generated synchronized sound effects (WAV or MP3)

How to Use

1. Upload a video (drag & drop or paste a URL).
2. (Optional) Write a prompt to describe sound context (e.g., “soft footsteps on wood,” “metal clangs,” “cinematic ambience”).
3. Set num_samples — the number of different sound versions to generate.
4. (Optional) Fix seed for reproducibility or randomize for variation.
5. Click Run — preview and download results.

Pro tips for best quality

• Use short, focused clips (≤10s) to maintain strong visual-sound alignment.
• For cinematic realism, include context in the prompt (e.g., “rainy street, distant thunder”).
• Generate multiple samples to audition variations before final mixdown.
• Adjust seed for subtle variations in timing and sound character.

Note

• Each sample is generated independently; total cost scales linearly with num_samples.
• Minimum billing covers 5 seconds even for shorter clips.
• Works best with clear, high-contrast motion — busy scenes may mix sound layers automatically.
