+  - Converts a single input file (AVI, MPG, MKV, MOV, etc.) into MP4
+  - Uses FFmpeg with modern compression (`libx264`, `AAC`, CRF 18)
+  - Automatically corrects timestamps (`-fflags +genpts`)
+  - Outputs to `~/Videos`
+- `convert-multiple` command:
+  - Merges multiple video inputs into one MP4
+  - Re-encodes using same compression settings
+  - Creates and cleans temporary file lists automatically
+- Config system (`config/config.json`) with optional `jq` parsing
+- Version tracking via `VERSION` file
+- Color-coded CLI feedback for INFO, WARN, ERROR, OK
+- Graceful error handling with safe exits and cleanup
