 **Codec-Specific Parameters:**
 - `K_keep`: Number of patches to keep.
-- `cache_dir`: Directory for cached codec patches. This is where the codec-selected patches will be stored/loaded.
 - `mv_compensate`: Motion vector compensation method (e.g., `median`).
+- `cache_dir` (optional): Directory for cached codec patches. Use this to specify where codec-selected patches are stored/loaded when you want to persist or reuse them.
