Built for editors.
Not everyone.
AMVs, phonk & car edits, gaming montages, VJ sets — if you cut footage to music, this is the tool you've been looking for. Drop in your clips and a track. Onset Engine maps every beat and drop, picks the right moments, and renders a finished edit. No hand-cutting.
What do you make?
Onset Engine does one thing, better than anything else: turn a folder of clips into a beat-synced edit. Find your lane.

However You Edit, One Engine Keeps Up
One-click for a finished edit in minutes, live mode for VJ sets, or full manual control when you want to sweat every frame.
One-Click Automation
Describe your vision in plain text. The AI maps every beat, selects clips by semantic match, and renders a complete edit - with transitions, pacing, and cinematic VFX. Done.
Live Performance
Real-time reactive visuals synced to your audio. Hardware-decoded playback with zero latency. Perfect for VJ sets, live shows, and installations.

NLE-grade precision. Smart cropping with face detection, 30+ cinematic VFX, triptych export, and OpenTimelineIO hand-off to Premiere or DaVinci.
From Raw Footage to Beat-Synced Edit
Four steps. No cloud. No waiting for uploads.
Ingest
Point Onset Engine at your video folder. The AI analyzes every frame using OpenCLIP, building a searchable vector database of your entire library.
Analyze
Drop in a music track. The audio engine maps every beat, energy curve, drop, and section boundary - creating a temporal blueprint that drives pacing, mood, and intensity.
Select
The driver system matches clip semantics to musical intensity. Calm footage gets quiet moments. High-energy clips hit the drops.
Render
Chunked, memory-safe rendering with cinematic VFX. Or skip rendering entirely - launch DJ Mode and mix live.
9 Built-In Presets
Each preset controls pacing, transitions, color grading, and effects - from raw, unfiltered cuts to full Hollywood prestige. Build your own and share them.
Why Editors Choose Onset Engine
AI That Understands Your Footage
OpenCLIP ViT-L/14 computes 768-dimensional visual embeddings for every clip in your library. The AI doesn't just detect motion — it semantically understands what's on screen. Search your entire footage archive by typing a text description, and the engine finds matching scenes instantly.
Beat-Synced by Math, Not Guesswork
librosa decomposes your music track into beats, onsets, energy curves, and section boundaries. The driver system maps high-energy clips to drops and calm footage to intros — every cut lands precisely on beat. Choose from 9 built-in presets or build custom pacing profiles via JSON.
