VideoHighlighter

English | 中文 | 日本語 | Español

Find and explain the moments that matter in footage you won’t upload — then export a cut, on your machine.

A local desktop app. Drop in raw video; it scores strong moments from scene, motion, audio, objects, actions and the transcript, shows you why each one scored on a signal timeline and in a report, then exports a highlight reel and the individual clips. Nothing is uploaded for analysis, and the basic pipeline needs no API key.

Free and open source (AGPL-3.0). Windows, macOS, Linux. Intel, AMD and NVIDIA GPUs.

App interface languages (About → Interface language): English, 简体中文, Español, Português (Brasil), Français, 日本語, Deutsch, 한국어, Bahasa Indonesia, Türkçe, Italiano, Polski, Tiếng Việt, Nederlands. This README is still English-first; translated copies above cover 中文 / 日本語 / Español.

It’s free. To make sure you see new releases in future, please click the motivation button: the ⭐ at the top of the page. It’s the cheapest payment we accept.

What people use it for

• A 4-hour Twitch or YouTube VOD → a few minutes of highlights. Crowd noise, your own reactions and scene changes all score, so the loud parts surface without scrubbing.
• A night of CCTV or trail-camera footage → the minutes something moved. Object detection plus motion, on hours of nothing, locally — which matters when the footage is of your own property.
• A GoPro or drone card → a finished film. The Auto tab finds the card, copies it off, cuts the highlights, builds the reel and lays music on the beat, as one resumable job.
• A match → the goals. Write a rule for “ball inside net” and it scores that event by where things are, instead of hoping an action model can tell it from how the frame looks.
• A long interview, lecture or podcast → chapters and subtitles. Local Whisper transcript, chaptered video, optional local translation.
• Dashcam or bodycam review → an account you can hand to someone. The report states what was measured, what was only said, and what it could not determine.

Not sure which detector fits your footage? docs/DETECTION-GUIDE.md covers what each one is good at and where it falls down.

What makes it different

Every run explains itself. The report is the arithmetic behind each kept moment — the per-signal point breakdown, what fired, what scored well and still missed the cut. It names the claims that came from the transcript and were never measured, instead of scoring them anyway. Open a real one →

Composition rules. You say what a combination of detections means for your footage — one class inside another, counted, held over a window — and that becomes an event under a name you choose. Because a rule re-reads detections that already exist, editing one and re-running costs milliseconds.

Install

Grab a build from Releases:

• Windows — run 00-VideoHighlighter-Windows-Setup.exe. Per-user, no admin. It is not code-signed yet, so click through More info → Run anyway.
• GitHub slow or blocked where you are? The same files are mirrored at dl.videohighlighter.com.
• macOS — drag the .dmg into Applications, then clear the quarantine flag once: xattr -dr com.apple.quarantine /Applications/VideoHighlighter.app (why).
• Linux / from source — pip install -r requirements.txt && python main.py. FFmpeg comes with it.

Portable builds, GPU setup, where it writes, and fixing an oversized UI: docs/INSTALL.md.

Pro edition

VideoHighlighter — this repository — is free software under AGPL-3.0, and stays that way. It includes offline analysis, live face detection, VR side-by-side playback, CLIP search, the composition engine, model training — including teaching a model from one box drawn in the player, which then keeps improving while the app is idle — and the model hub.

VideoHighlighter Pro is a separate paid edition that adds real-time work on top: live object and action overlays during playback, teaching a live category mid-playback, find-more-like-this search, open-vocabulary detection and counter/scoreboard detection.

Explanation is not among them. The report, the findings and the advisor are identical in both editions — a cloud tool gives you a button and a result you cannot interrogate; answering “why”, locally, is what this is instead.
