Sonilo

Sonilo creates soundtracks and sound effects from video. Users upload an MP4, MOV, or M4V file (or use text prompts) and Sonilo generates music and sound effects matched to the video length, with multiple variations by default. The page describes plugins for Adobe Premiere Pro, Unity, Godot, Epic Games Fab, Roblox Studio, and Defold, and a video translation feature that translates speech into 24 languages while keeping music and sound effects. Commercial use is available on Pro, Premium, Enterprise, and eligible API accounts; the page states the model is trained only on licensed catalogs. A free tier with 2,000 credits every 2 weeks is offered, with preview-quality exports only.
