+### Verbosity 🔈
+
+```bash
+# More detail (commands + error lines)
+vid-repair fix -v /path/to/videos
+
+# Less detail (summary only)
+vid-repair scan -q /path/to/videos
+```

 **Note:** `fix` always performs a full scan first, then repairs only if issues are found.  
 Use `scan` when you just want a report without making changes.
