Video to SFX

How video-to-SFX compares

Three common ways to add sound to mute footage: picture-locked video-conditioned SFX, text-to-SFX suites, and open-source video-to-audio models.

• Mirelo video-conditioned SFX

  How it works

  Generates picture-locked sound from the video itself, with optional text hints for off-screen detail.

  Iteration

  Iterate, extend, loop, and inpaint takes in Studio, plugins, and the API.

  Best for

  Silent clips and AI-generated video that need Foley-style, frame-timed effects.

• Text-to-SFX suites

  How it works

  Generate from a written prompt (ElevenLabs, Adobe Firefly, and similar), then place the clip on the timeline.

  Iteration

  Re-prompt to change timbre; timing to picture is manual.

  Best for

  Off-screen, imaginary, or library-style sounds when you do not have matching footage.

• Open-source V2A

  How it works

  Research video-to-audio models such as MMAudio, HunyuanVideo-Foley, FoleyCrafter, and Woosh.

  Iteration

  Typically one-shot demos or self-hosted inference, without a production iterate, extend, and inpaint workflow.

  Best for

  Experiments, papers, and local prototypes.

Frequently asked questions

What is video-to-audio?

Video-to-audio (also called video-to-SFX) is AI Foley for silent or AI-generated video: a model watches the picture and generates sound effects timed to on-screen action, rather than inventing audio from a text prompt alone.

How is video-to-SFX different from text-to-SFX?

Video-to-SFX is video-conditioned and picture-locked: the model sees the clip and times effects to on-screen action. Text-to-SFX suites such as ElevenLabs and Adobe Firefly generate from a written prompt, then you place and sync the audio yourself.

Is video-to-audio the same as AI Foley?

AI Foley is generated sound for on-screen action — footsteps, impacts, cloth, whooshes — without a Foley stage. Video-to-audio is the usual name for models that do that from picture, including AI Foley for silent or AI-generated video.

How do open-source V2A models compare with Mirelo SFX?

Open-source video-to-audio models such as MMAudio, HunyuanVideo-Foley, FoleyCrafter, and Woosh are research systems and demos. They are useful for experiments and self-hosting. Mirelo SFX is a production video-conditioned SFX product with picture-locked generation plus iterate, extend, and inpaint in Studio, plugins, and the API.

Where can I use Mirelo video-conditioned SFX?
