Your Photos, on the Beat

A free update for every license owner. Every feature is in the free Demo, too.

Photos, moving to the music

Add photos next to your videos, iPhone HEIC included. Each one moves across its shot with a slow push, pull or pan, sized to the music and aimed at faces.

Use my photos and clips

Every photo and clip you pick, shown once, each cut on the beat, in the order you choose: the date taken, file name, shuffled, or the clips spread among the photos.

Live, and softer when it's quiet

Photos play in DJ Mode too. Transitions crossfades one shot into the next where the music is calm, or between every shot.

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

Press New video, pick your clips and a song: the AI maps every beat, picks clips that match the music, and cuts a draft of the whole song in minutes - even from long footage. Describe what to show in plain words if you like, then render it with transitions, pacing and cinematic VFX. Done.

From Raw Footage to Beat-Synced Edit

Four steps. No cloud. No waiting for uploads.

1

Ingest

Point Onset Engine at your video folder. The AI analyzes your footage, building a searchable fingerprint of every clip in your library.

2

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.

3

Select

The driver system matches clip semantics to musical intensity. Calm footage gets quiet moments. High-energy clips hit the drops.

4

Chunked, memory-safe rendering with cinematic VFX. Or skip rendering entirely - launch DJ Mode and mix live.

Why Editors Choose Onset Engine

AI That Understands Your Footage

The AI builds a searchable fingerprint of what's in every clip in your library - with the Standard model by default, or High Quality for even better clip matching. It 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

AI beat detection finds every beat and downbeat in your music track and maps its 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.

Works Offline After Setup

No cloud uploads. No processing queues. No per-minute AI fees. Onset Engine runs entirely on your local hardware - on NVIDIA cards, CUDA accelerates AI analysis and NVENC speeds up 4K exports; AMD Radeon cards get hardware-encoded exports via AMF; any modern CPU handles the rest. Your footage never leaves your machine, and you never wait for a server.
