QuickStudio - AI Video Editor

QuickStudio is a non-destructive multitrack video production studio for Android. 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.
