Video models bake in music you never asked for. Instead of regenerating the video until it doesn’t, keep the clip you like and get clean sound around your dialogue.
Every generated clip comes with its own audio, so stitched edits jump between ambiences and music. Run your full edit through Mirelo and it sounds like one continuous scene.
Long-form content shouldn’t mean sound designing clip by clip. Finish your edit, upload it once, and get one consistent soundtrack.

SFX 2.0 separates the speech from your clip and keeps it in the output while generating new effects and ambience around it. Speech preservation is on by default for video-to-SFX requests; turn it off when you want sound effects only.
SFX 2.0 supports videos up to 10 minutes in Studio and the API. For longer edits, contact us to discuss your requirements. Contact us about Enterprise.
Yes. Mirelo SFX 2.0 reads the visible action, timing, and environment, so effects land where the action lands instead of needing manual trimming and alignment.
SFX 2.0 is live in the Mirelo Playground, Mirelo Editor, the Mirelo API, Mirelo MCP and as Mirelo plugins for Adobe Premiere Pro, DaVinci Resolve and Roblox (coming soon). It is also available on our partner platforms including Runway and Fal, other platforms coming soon.
