Mirelo launched SFX 2.0, a video-to-SFX model that watches your video, strips out un-prompted music, keeps dialogue, and builds full sound design synced to the action and consistent across clips. It's live via API on Runway and fal.

The accompanying blind test chart shows it preferred in every matchup: 81% vs 9% over Sony Woosh, 63% vs 18% over Kling-Foley, and 46% vs 33% over Sonilo (25 raters per round). The poster notes the Kling-Foley gap was wider than expected.
