 For the best visual quality, at the expense of slower encoding and higher bitrate:
 
 - Set `presetName=slow`.

 #### Achieving High Encoding Speed (High FPS)
 
 If you want to maximize encoding speed and can trade off some compression efficiency:
 
 - Set `presetName=fast`.
-- Use high QP values, e.g., `rate=32-42-4` or up to `rate=51-51-4`.
+- Use high QP values, e.g., `rate=32-42-4` (up to `rate=51-51-4`).
 - Disable double layer: `doubleLayer=false`.
 - Lower internal geometry bit depth:
   - `geoBitDepthVoxelized=8`
