🧰 ExifTool (strongly recommended for video metadata read/write)
- Windows: download from exiftool.org and add exiftool.exe to PATH
- macOS: brew install exiftool
- Linux (Debian/Ubuntu): sudo apt install libimage-exiftool-perl
🎬 ffprobe (optional; improves video metadata extraction, usually installed with FFmpeg)

🚀 Key Features

⚡ Fast browsing: paginated file listing, virtualized grid, lazy metadata batch fetch, optional auto-refresh.
⭐ Ratings & 🏷️ tags: set rating 0–5 and tags; shows badges on cards and in the viewer.
🧠 Prompt/workflow inspector: reads generation data from images and videos (with sibling PNG fallback when needed).
🔎 Filters & collections: search, min rating, tag filter, smart filters, and collections stored in _mjr_collections.
🖼️ Viewer + A/B: single viewer + A/B compare, zoom/pan, video playback, rating HUD.
🧷 Hover info: optional native tooltip on cards (filename, folder, size/date, rating/tags, workflow state).

🎞️ Demos (GIF)

GIFs are large; these are linked (not embedded) to keep the README fast. Full-res captures are kept locally as examples/*_full.gif (gitignored):

Windows Explorer can be inconsistent for MP4/MOV/MKV/WEBM metadata. For videos, the manager uses a redundant write strategy:

✅ Always writes:
- XMP:Rating (0–5)
- XMP:Subject (tags list; ; separator)
✅ Best-effort writes (does not fail the operation if unsupported):
- Microsoft:SharedUserRating (0–99 “percent” scale used by Explorer)
- Microsoft:Category (tags; tag1; tag2)
🛡️ Preserves embedded ComfyUI workflow JSON stored in comment-like fields by copying the original tags (-tagsFromFile @ ...) before writing rating/tags.
⏳ Handles “file not ready/locked” right after generation: retries ExifTool up to 5 times with exponential backoff for common “cannot open/write” errors.
📥 Read priority for videos: ExifTool values are treated as the source of truth (XMP first, Microsoft fallback), then Windows Property System.

cd ComfyUI/custom_nodes
git clone <this-repo-url> ComfyUI-Majoor-AssetsManager
pip install -r ComfyUI-Majoor-AssetsManager/requirements.txt

Restart ComfyUI.

Hotkeys are ignored while typing in an input/textarea.

0‑5: set rating for current/selected files (0 clears).
Space: open viewer (1 selected) or A/B compare (2 selected; uses the first two).
Ctrl/Cmd + A: select all filtered files.

Selection behavior (Explorer‑like):

Esc or Space: close viewer.
ArrowUp / ArrowDown: previous/next asset (when navigation is enabled).
0‑5 (including numpad): set rating (when viewer rating hotkeys are enabled).
ArrowLeft / ArrowRight: step videos +/- 1/30s (when frame-step hotkeys are enabled).
F: fit/reset view.

Main ones to know:

🧩 Majoor: Panel Integration (reload to apply): show in sidebar, bottom, or both.
📄 Majoor: Page Size (files per request): pagination chunk size (default 500).
🛈 Majoor: Hover Info Tooltips: show/hide card hover tooltips.
🔁 Auto-refresh: enabled/interval/focus-only.
🖼️ Viewer: autoplay/loop/mute/navigation/rating HUD.

Sidecars: .mjr.json are enabled by default on non-Windows; on Windows default is OS metadata. Override with MJR_ENABLE_SIDECAR / MJR_FORCE_SIDECAR.
Output helper folders: collections in _mjr_collections (inside your ComfyUI output directory).
API endpoints live under /mjr/filemanager/* (e.g. /files, /metadata, /metadata/batch, /metadata/update).
Timeouts (to prevent hangs) are configurable via env vars: MJR_META_EXIFTOOL_TIMEOUT, MJR_META_FFPROBE_TIMEOUT, MJR_EXIFTOOL_READ_TIMEOUT, MJR_EXIFTOOL_WRITE_TIMEOUT, MJR_EXIFTOOL_PRESERVE_TIMEOUT, MJR_FILE_MANAGER_TIMEOUT.
