# SendStudio

> Professional media asset workspace for production studios, post-production, game development, VFX, and creative teams.

SendStudio is a media asset management and client review platform that combines bidirectional file sync, secure client review, frame-accurate video and image commenting, 3D model viewing, HDR video playback, audio visualization, comic/ebook reading, slate generation, and project organization in a browser-based workspace with a retro OS9-styled interface. Also available as a native desktop app for macOS, Windows, and Linux.

## Core Capabilities

- **Bidirectional File Sync**: Sync local folders to the cloud from your browser — no app install required. Three modes: bidirectional (two-way), upload-only (backup), download-only (mirror). SHA-256 change detection, conflict resolution with side-by-side comparison, file locking across teams, automatic scheduling, and real-time file watching. Uses the File System Access API (Chrome/Edge).
- **Image Commenting**: Click anywhere on an image to place a comment pin at exact pixel coordinates. Real-time collaboration with threaded replies, resolved/unresolved status, and author attribution. Export comments to 6 formats.
- **Video Commenting**: Frame-accurate timecoded comments on video. Click to place, click to seek. Export to EDL (DaVinci Resolve), Avid Markers, CSV, JSON, Markdown, or plain text.
- **Audio Commenting**: Place comments at specific audio timestamps for precise feedback on music, dialogue, and sound design.
- **3D Model Viewer**: Review GLTF, GLB, OBJ, FBX, DAE, STL, PLY, 3DS, and USDZ in the browser. Orbit, pan, zoom. 7 camera presets, 4 lighting presets, wireframe mode, material inspector, texture preview, animation playback, screenshot capture.
- **HDR Video**: Playback for HDR10, HDR10+, Dolby Vision, and HLG with automatic detection and SDR display tone-mapping.
- **Audio Player & Visualization**: Web Audio API player with real-time oscilloscope waveform, 64-band spectrum analyzer, per-channel VU meters (mono, stereo, 5.1 surround), shuttle playback (JKL), and loop mode.
- **Timecode Overlay**: SMPTE timecode during playback. All standard frame rates (23.976–60fps). Drop-frame support. No re-encoding.
- **Secure Sharing**: Password-protected, time-limited review links. Download control. View tracking. Watermarking with custom logos. Reviewer sign-off accountability.
- **External Upload Folders**: Secure upload links for outside vendors and clients — no account required. Contributors can submit files without seeing other project content.
- **Comic & Ebook Viewer**: Read CBZ, CBR, PDF, and EPUB files with automatic panel detection, progressive page extraction, and natural sort ordering.
- **Text & Subtitle Viewer**: Preview TXT, Markdown, SRT, VTT, CSV, and RTF files with syntax rendering.
- **PSD Preview**: Photoshop composite preview with dimensions, color mode, bit depth, and layer count metadata.
- **Slate Generator**: Film-style title cards for video production. Export to PNG, JPEG, TIFF at HD (1920x1080) or UHD (3840x2160). Overlay onto video. Customizable fonts and saveable presets.
- **Metadata Extraction**: Image EXIF, video codec/resolution/HDR format, audio codec/channels, 3D model vertices/materials/textures. Client-side, no server round-trips.
- **File Versioning**: Upload new versions, version history with notes, side-by-side A/B comparison, gang-sync video playback for comparing takes.
- **Upload Engine**: Batch uploads with pause & resume, multipart for files over 5 GB, auto-retry, junk file filtering, deduplication, and persistent upload history.
- **Desktop File Explorer**: Icon view with freeform drag positioning, list view with sortable columns, gallery view with thumbnails, custom folder icons, marching ants selection, auto-arrange, context menus, and recycle bin with recovery.
- **File Locking**: Advisory file locks across devices with heartbeat TTL, lock transfer requests, and admin force-release. Prevents accidental overwrites in multi-user sync.
- **Theme Customization**: 4 color schemes (Monochrome OS9, XP Blue, Magenta, Green Matrix), customizable accent and highlight colors, 3 font sizes.
- **Native Desktop App**: Tauri-based app for macOS, Windows, and Linux with system tray sync status, OS notifications, and auto-updater.
- **Team Management**: Multi-organization support, team member invites, role-based access (admin, editor, viewer, contributor), per-project access control, per-org storage and project isolation.
- **Link Locker**: Inventory management for all active share links — view, edit, expire, and revoke from a single dashboard.
- **Project Organization**: Hierarchical folders, drag-and-drop, gallery viewer with folder navigation, breadcrumbs, trash with recovery, custom folder icons.
