Welcome to Onset Engine

Local-first, GPU-native video intelligence. Beat-synced editing, AI-powered clip selection, and cinematic VFX — all running on your hardware.

GPU-Accelerated Ingest

OpenCLIP ViT-L/14 analyzes every clip on your local GPU (CUDA, MPS, or CPU fallback). 768-dimensional embeddings enable semantic search over your entire library.

Beat-Synced Editing

librosa extracts beats, energy curves, and drop zones from your music. Every cut lands within ±200ms of a musical onset.

One-Click Autopilot

Describe your vision in plain text. The AI ingests, selects, and renders a full beat-synced video — no manual timeline work.

9 Built-In Presets

From RAW cuts to full PRESTIGE cinematography. Each preset controls pacing, transitions, VFX, and color grading.

Text Descriptions

Two text fields auto-generate a 4-tier semantic driver. No JSON knowledge required — power users can still use custom drivers.

100% Offline

No cloud uploads. No telemetry. No subscriptions. One-time purchase. Your footage stays on your machine.
