AI Video Editor

Only for Mac

Mac

Build polished videos with a responsive multitrack timeline, keyframes, local captions, review-first AI, voiceover, thumbnails, and verified publish packages. QuickStudio is a non-destructive multitrack video production studio for iOS and macOS. Assemble video, audio, music, images, titles, subtitles, and chapters in one project, then deliver a verified package for YouTube or social media. TIMELINE EDITING: - Work with up to six video and six audio tracks, plus dedicated subtitle and chapter lanes. - Trim, split, ripple-delete, roll, move, duplicate, snap, zoom, and undo or redo edits without changing original media. - Animate position, scale, rotation, crop, opacity, volume, pan, and effect parameters with keyframes and easing. - Add titles, color clips, Ken Burns images, freeze frames, transitions, color correction, looks, blur, mosaic, vignette, sepia, and chroma key. LOCAL AND REVIEW-FIRST ASSISTANCE: - Generate on-device Whisper captions, import or export SRT and VTT, search subtitle text, shift timing, and choose sidecar or burn-in delivery. - Review Silence Cut, BGM Assist, Chapter, Shorts, subtitle cleanup, and Publish Copy proposals before applying them; accepted edits remain undoable. - Connect an MCP-compatible agent to import media, edit the timeline, add subtitles, save projects, and export videos through chat. AUDIO AND DELIVERY: - Record voiceovers at the playhead, detach audio, mix up to six tracks, set keyframed volume and pan, duck music under speech, and normalize delivery loudness. - Export MP4, MOV, WebM, M4A, MP3, or WAV with platform-aware hardware encoding, progress, cancellation, safe partial cleanup, and Original-only final rendering. - Create exact-frame PNG or JPEG thumbnails, SRT/VTT subtitles, chapter text and metadata, portable Project Archives, and atomic Publish Packages. - Publish Packages can include the main video, thumbnail, subtitles, chapters, accepted description copy, selected vertical Shorts, hashes, and a YouTube Studio handoff. PROJECTS AND PERFORMANCE: - Save deterministic .qstudio projects with autosave, crash recovery, conflict copies, missing-media Relink, and stable lineage between Original, Project, Sidecar, and Export artifacts. - Keep editing responsive with adaptive preview quality, mobile proxies, render cache, hardware decoding, and clear fallback disclosures. - Use keyboard shortcuts, touch gestures, accessible labels, high text scaling, light Library surfaces, and a focused dark editing workspace. PRIVACY AND CONTROL: - Original media is never modified silently. Captions and signal analysis run locally; provider-based copy assistance shows an exact data preview and requires consent. - No QuickStudio account or direct social-media credential is required for local editing and export. QUICKSTUDIO PRO: - Every editing, AI, MCP, archive, and export feature remains available in Free. - Pro removes the mobile Library banner and daily desktop reminders after the seven-day trial. - Choose a lifetime purchase or a yearly subscription to support continued development.
