## Internal / Hardcoded Settings
|
|
These settings are not exposed to the user in the Tdarr UI and are hardcoded in the plugin logic:
|
|
|
|
* **qmin**: `10` (Minimum Quantizer, prevents extreme quality boost that wastes space)
|
|
* **qmax**: `50` (Maximum Quantizer, prevents extreme quality loss)
|
|
* **Buffer Size**: Calculated as `2.0 * maxrate` (only if maxrate is set).
|
|
* **Pixel Format**:
|
|
* For 8-bit: Implicit (standard `yuv420p` usually).
|
|
* For 10-bit: Explicitly set to `yuv420p10le`.
|
|
* **Audio/Subs**: `-c:a copy -c:s copy` (Passthrough).
|
|
* **Data Streams**: `-dn` (Discarded).
