 - **ASCII Mode Recommended:** `--cols 200` to `--cols 240` (Best balance of text detail and cinematic 30 FPS performance).
 - **Pixel Mode Recommended:** `--cols 600` to `--cols 900` (Provides near-HD visual quality. Performance heavily depends on your machine's CPU/VRAM).
+- > **Smart Defaults:** If you do not specify a `--cols` value, ASCILINE automatically defaults to `450` when Pixel Mode is enabled, and `200` for standard ASCII text mode. 
 - > ⚠️ **Hardware Limits & A/V Sync:** If you push the `--cols` too high for your specific hardware (e.g., `1350` on a laptop vs a gaming desktop), the Python backend won't be able to encode and send the massive frames fast enough. When the video stream lags behind the audio, you will experience A/V desync (audio finishing early). If this happens, simply lower your `--cols` value!

 Video paths are resolved automatically — the engine checks the project root and the `videos/` subfolder, so you can write just the filename.
