 ## Output Files
 
-All output files are saved to the `output/` directory by default:
+Each video gets its own timestamped output directory:
 
-- **`output/<video>_enhanced.txt`** - Enhanced transcript ready for AI summarization
-- **`output/<video>.json`** - Whisper transcript (if `--run-whisper` was used)
-- **`output/<video>_vision.json`** - Vision analysis results with timestamps (if `--use-vision`)
-- **`output/<video>_ocr.json`** - OCR results with timestamps (if using OCR)
-- **`frames/`** - Extracted video frames (JPG files)

+### Manifest File
+
+Each processing run creates a `manifest.json` that tracks:
+- Video information (name, path)
+- Processing timestamp
+- Configuration used (Whisper model, vision settings, etc.)
+- Output file locations
+
+Example manifest:
+```json
+{
+  "video": {
+    "name": "meeting.mkv",
+    "path": "/full/path/to/meeting.mkv"
+  },
+  "processed_at": "2024-10-19T14:30:22",
+  "configuration": {
+    "whisper": {"enabled": true, "model": "base"},
+    "analysis": {"method": "vision", "vision_model": "llava:13b", "vision_context": "code"}
+  }
+}
+```
 
 ### Caching Behavior
 
-The tool automatically caches intermediate results to speed up re-runs:
-- **Whisper transcript**: Cached as `output/<video>.json`
-- **Extracted frames**: Cached in `frames/<video>_*.jpg`
-- **Analysis results**: Cached as `output/<video>_vision.json` or `output/<video>_ocr.json`
+The tool automatically reuses the most recent output directory for the same video:
+- **First run**: Creates new timestamped directory (e.g., `20241019_143022-meeting/`)
+- **Subsequent runs**: Reuses the same directory and cached results
+- **Cached items**: Whisper transcript, extracted frames, analysis results
+- **Force new run**: Use `--no-cache` to create a fresh directory
 
-Re-running with the same video will use cached results unless `--no-cache` is specified.
+This means you can instantly switch between OCR and vision analysis without re-extracting frames!
 
 ## Workflow for Meeting Analysis
 
@@ -310,6 +341,15 @@ Options:
 - **`--vision-context dashboard`**: Extracts metrics, trends, panel names
 - **`--vision-context console`**: Captures commands, output, error messages
 
+**Customizing Prompts:**
+Prompts are stored as editable text files in `meetus/prompts/`:
+- `meeting.txt` - General meeting analysis
+- `code.txt` - Code screenshot analysis
+- `dashboard.txt` - Dashboard/monitoring analysis
+- `console.txt` - Terminal/console analysis
+
+Just edit these files to customize how the vision model analyzes your frames!

 ### Scene Detection vs Interval
 - **Scene detection**: Better for presentations with distinct slides. More efficient.
 - **Interval extraction**: Better for continuous screen sharing (coding, browsing). More thorough.
