SceneFX AI: let AI do the sound design for your video
Adding professional sound effects and background music to a video normally takes hours: searching libraries, testing fits, cutting to timestamps, adjusting levels. Upload subtitles or a video to SceneFX AI and AI analyses each scene’s emotion, pacing and audio needs; matching sound effects, music and emotion-tuned voiceover are generated and auto-mixed to the YouTube standard.

Why SceneFX AI?

Ready for your editor
Take the result as EDL, markers CSV, FCPXML or a stems ZIP and use it in your own editing software.
Transparent output
AI-generated content can carry C2PA content credentials, so its origin is clear.
