Split, Sync, and Narrate Videos in Your Browser

Beat2Cut is a free, browser-based beat detection tool built for video editors — Music Tempo, Drum Beat, and Onset algorithms, no cost, no account. Audio analysis runs locally, so your music files never leave the browser for detection. Video Studio and Voiceover need sign-in; exporting video costs credits on Free and is included with Pro.

To sync music beats to video in Final Cut Pro, use Beat2Cut's automatic detection workflow. Open your audio file (MP3, WAV, M4A, or AAC), let the algorithm find every beat with precise timing, adjust sensitivity if needed, then export the markers as FCPXML. Import that file into Final Cut Pro and the markers line up with your track — replace the placeholder clips with your footage and the cuts snap to the beat.

Cutting to the beat gets effortless with Beat2Cut. Upload your track, let it detect every beat, then export FCPXML with beat markers and import into Final Cut Pro — placeholder clips are already sitting on each beat. Drag your footage onto them and the cuts fall into rhythm instantly. The exported FCPXML alternates 110%/100% scale values too, adding a subtle zoom on every cut.

FCPXML (Final Cut Pro XML) is the native project file Final Cut Pro uses to import and export timeline data. When Beat2Cut exports beat markers, it builds an FCPXML timeline with a marker at every detected beat — import it and the markers appear instantly, ready to edit against, with no plugins or extra software involved.

No installation required — Beat2Cut runs in a modern web browser. Free audio beat detection works without an account and analyzes audio on your device. Video Studio and Voiceover need sign-in: source video for scene detection and export stays in the browser, while Voiceover calls third-party AI speech providers online.

Beat2Cut runs three detection modes — Music Tempo for general music with a steady rhythm, Drum Beat for EDM and hip-hop with a strong kick, and the experimental Onset mode for complex rhythms. Accuracy depends on how clean and consistent your track's rhythm is; adjust sensitivity and re-detect if the first pass isn't quite right. Most tracks land production-ready markers on the first try.

Audio beat detection is free and needs no account. Video Studio and Voiceover need sign-in, and new Free accounts start with 100 one-time trial credits. Delivering a video export (MP4, ZIP, or FCPXML) costs 10 credits on Free; the Pro monthly subscription includes export and a larger shared Voiceover credit allowance.

AI Voiceover turns a script into narration once you're signed in with credits to spend. Generation runs through third-party AI speech providers — currently Fish Audio and MiniMax — so your script and voice settings leave the browser for synthesis, and the resulting audio can save to your account. Export MP3, WAV, a sentence ZIP, or subtitles; sentence-level retakes recompose in this browser session and don't carry over unless you export first. Free accounts start with 100 one-time trial credits, and Pro raises the recurring allowance.

Detection and export encoding for beats, scenes, and video all run in your browser — source media isn't uploaded for those steps. Sign-in, billing, and Voiceover are the online parts: Voiceover sends your script to third-party AI speech providers (Fish Audio, MiniMax) and stores the generated narration with your account. We never use your scripts or generated audio to train our own speech models.

Yes — Beat2Cut's outputs are yours to use in personal and commercial projects alike. Beat markers, scene markers, FCPXML files, and exported clips are fair game for client work, YouTube videos, ads, films, or anything else you're producing. Your media stays on your device throughout.

Video scene detection automatically finds where a video's content changes — cuts, transitions, or any significant visual shift. Beat2Cut compares consecutive frames for changes in content, lighting, or composition, marks each one as a scene boundary, and exports the results as FCPXML so you can jump straight to cut points or align edits with the existing scene changes.

Open your video file (MP4, MOV, WebM, or M4V, up to 2GB) in Video Studio, pick the detection mode that fits your footage — Stable for most content, Aggressive for fast cuts — and adjust the sensitivity slider: higher catches more changes, lower only the major transitions. Run detection, then export the scene markers as FCPXML and import them into Final Cut Pro to see a marker at every scene change.

Beat2Cut supports MP4, MOV, WebM, and M4V up to 2GB. Detection and export encoding both run in your browser, so source video is never uploaded for those steps — frames are sampled locally for analysis. Very compressed or low-quality footage can reduce detection accuracy.

Video scene detection itself is free and unlimited once you sign in — the only paid step is delivering the export. On Free, each downloaded MP4, ZIP, or FCPXML costs 10 credits; Pro includes export at no extra charge. All processing runs locally in your browser.

Open your video in Video Studio, set the detection mode for your content, and adjust sensitivity. Run detection and Beat2Cut analyzes the footage frame by frame to catch every scene change, cut, or transition — then export the markers as FCPXML and import them into Final Cut Pro for a marker at every boundary, ready to navigate, organize, or split your footage.

Stable mode suits most footage — vlogs, interviews, documentaries — and handles camera movement and lighting shifts well. Aggressive mode is more sensitive to hard cuts and fits fast-paced content like music videos or action sequences. Aim for the setting that catches every real cut without flagging small movements as new scenes, and re-run detection if you want to try another setting.

Yes — Beat2Cut handles shot boundary detection for long videos up to 2GB, and detection itself is free and unlimited once you're signed in. Markers export as FCPXML; delivering the export costs 10 credits on Free and is included with Pro.

Beat2Cut automates two of post-production's most tedious tasks — finding scene boundaries in your footage and detecting music beats for rhythm-synced edits. Export either as FCPXML markers and import them straight into Final Cut Pro to navigate scene boundaries or align cuts to the beat.

Beat2Cut's browser video editor kicks in after sign-in and scene detection: select the scenes you want and choose an export — single video, individual clips ZIP, or FCPXML. Detection is free and unlimited; delivering the export costs 10 credits on Free, and is included with Pro.

Beat2Cut ships three video export formats — Single Video (merges scenes into one MP4), Individual Clips (a ZIP of separate MP4s), and FCPXML (a Final Cut Pro project file) — all encoded with local stream-copy. Delivering any export costs 10 credits on Free and is included with Pro.

Yes — Beat2Cut uses stream-copy powered by the WebCodecs API and MP4Box.js. It copies the original compressed video data into a new container without re-encoding, so codec, resolution, bitrate, and quality stay exactly as they were. Exports finish in seconds, not minutes.

Single Video merges every selected scene into one continuous MP4 — ideal for a ready-to-share edit. Individual Clips exports each scene as its own MP4, packaged in a ZIP — better for social clips, highlight reels, or organizing scene by scene.
