From raw clips to rough cut in minutes.
Drop in your footage and music. The edit builds itself. Export to Final Cut Pro.
Join the WaitlistThe hardest part of video creation isn't shooting — it's the hours spent in the edit bay selecting clips, syncing to music, cutting around filler words, and mixing audio levels. CineBuild compresses that process from hours to minutes.
Drop your video clips and music into CineBuild. Assign A-Roll (talking heads, interviews) and B-Roll (cutaway footage) with a single keypress.
Choose a mood, pick a style preset, set your target duration. Or just hit go — the defaults are smart.
Every clip is analyzed: dialogue transcribed, scenes detected, loudness measured, beats mapped, story identified. Then a complete timeline is assembled with cuts, transitions, music sync, and sound effects.
Watch the edit in the built-in timeline editor. Tweak anything. Then export to Final Cut Pro for finishing, or render directly.
Every decision a professional editor would make — clip selection, sequencing, pacing, trim points, transitions, audio placement, and narrative structure — in a single pass. No robotic patterns. CineBuild understands story tension, counterpoint, and when to hold a shot.
Story arcs are detected across your footage — hooks, introductions, rising action, climax, and resolution. Setup/payoff relationships are mapped so the edit tells a coherent story, not just a highlight reel.
Organic, varied sequencing. B-Roll montages of 3–5 clips. Strategic long holds for emotional weight. Tension-release cycles with mandatory cooldowns. The edit feels human because it's built on professional editing principles.
Music Video (fast cuts, beat-locked), Documentary (long holds, dialogue-driven), Family Memory (face-focused, warm), Action (frenetic, motion-heavy), Contemplative (slow, atmospheric). Or build your own configuration.
Assign interview and cutaway footage. All dialogue is transcribed, filler words and repeated takes detected, and the edit is built around the strongest spoken content.
Speech is transcribed with per-word timestamps and confidence scores. 17 filler words detected (um, uh, like, you know, basically...) with contextual awareness — distinguishing when "like" is filler vs. legitimate.
When you've recorded multiple takes of the same content, duplicates are identified and the strongest performance is selected. Or get suggestions and choose yourself.
Relevant B-Roll is automatically placed based on what's being discussed. Five matching priorities: activity match, semantic category, keyword, emotional resonance, thematic relevance.
Four modes — concurrent (shows what's being discussed), anticipatory (shows before it's mentioned), reactive (shows after), or bridging (connects segments).
Three sensitivity levels. Removes dead air and verbal tics while preserving meaningful pauses.
Upload your song and the entire structure is mapped — BPM, beat grid, song sections (intro, verse, chorus, bridge, drop, outro), vocal sections, energy curves, and key moments.
Not all beats are equal. Kick drums trigger major transitions. Snare hits drive mid-scene cuts. Cymbal crashes mark section changes. Hi-hat patterns pace rapid montages.
Verses map to ordinary-world footage. Choruses and drops sync to emotional peaks. Bridges match reflective moments. Outros wrap the conclusion.
Cuts land slightly before the beat, matching how professional editors create the perception of sync. Music is pulled out entirely when the moment demands it — for dialogue emphasis, dramatic punctuation, or chapter transitions.
11 categories of production-ready sounds — whooshes, impacts, stingers, risers, downlifters, foley (footsteps, cloth, props, body), ambience (interior, exterior, special), and transitions. UCS naming convention compliant.
Your SFX library is reviewed, each scene is understood, and specific sounds are placed at precise moments. Not random — intentional.
DSP analysis finds the exact perceptual "hit point" in every sound file. A pre-roll formula ensures impacts land on the frame, risers peak at the moment, and ambient beds fade in naturally.
Sub-bass drones 4–8 seconds before a hit, risers sweeping up over 6–16 seconds, a brief silence before impact, then the stinger. Cinematic sound design, automated.
Dialogue at -12dB, music at -14dB solo / -28dB under dialogue, SFX layered at category-appropriate levels. ITU-R BS.1770-4 loudness measurement on every clip with 0.5-second temporal resolution.
5 curve types (linear, S-curve, parabolic, step, logarithmic). Music ducks for speech automatically. Every clip's actual loudness profile informs the mix.
ITU-R BS.1770-4 loudness measurement with K-weighting. Integrated LUFS, true peak, loudness range, and temporal contours for source-level-aware mixing decisions.
Apply .cube LUTs for color grading during preview and export. Auto-mapping for Sony camera profiles (S-Log3, S-Gamut3.Cine). Parses XML sidecar files for metadata.
Full FCPXML export with storylines, connected clips, and magnetic timeline features. The edit round-trips to FCP for professional finishing.
Built with SwiftUI and AVFoundation. Metal GPU acceleration for preview. No FFmpeg, no Electron, no compromises. Designed for Apple Silicon.
Previously analyzed clips are cached. Re-edit the same project with different settings without re-uploading or re-analyzing.
Rate each skill's output (transcription, scene analysis, narrative structure, etc.) on a 0–100 scale with notes. The system refines its processing instructions based on your feedback.
Star-rate your favorite clips before the edit. 4–5 star clips get a 3x selection score multiplier. 5-star clips receive special SFX treatment.
The editorial pipeline is built from 15 independent skills (transcription, B-Roll selection, narrative assembly, mood analysis, SFX suggestions, timeline generation, and more) organized in a dependency graph. Each can be refined independently.
You shoot hours of footage at birthdays, holidays, and milestones. CineBuild picks the best moments, cuts around the shaky bits, syncs to your chosen song, and delivers a video your family will actually watch. No editing skills required.
Spend your time on story, not assembly. CineBuild transcribes all your interviews, removes filler words and bad takes, semantically matches B-Roll to what's being discussed, and builds a rough cut that respects narrative structure. Export to Final Cut Pro and refine from there.
Turn conference recordings, product demos, and internal comms into polished videos. The tedious work is handled — trimming silences, cutting between speakers and slides, adding professional transitions and background music. Broadcast-standard audio levels included.
Beat-synced editing that actually understands music structure. Cuts land on kicks, transitions hit on cymbal crashes, and the visual energy follows the song's arc from verse to drop. Upload your track and let CineBuild cut your footage to the beat.
You shot 6 hours of footage. The client wants a 5-minute highlight reel by next week. CineBuild analyzes all your clips, identifies the key moments, and assembles an emotionally structured edit with music, sound design, and smooth pacing.
Get from shoot to publish faster. CineBuild handles the rough cut — removing dead air, selecting the best takes, adding B-Roll where you'd want it, and syncing transitions to your intro music. You handle the creative polish.
