**Export Tagging & Linking Options**

* **Tag All H.264 Exports as ‘High Unconstrained’**\
  When enabled, H.264 exports will be tagged using the general **'High Unconstrained'** profile for maximum compatibility.

  > When disabled, Tin Man will attempt to use the specific H.264 profile that best matches the encoding parameters.
* **Use MCA Audio Labels**\
  Enables descriptive **Multi-Channel Audio (MCA) labeling** for exported audio tracks, such as Front Left, Front Right, Center, etc.

  > Useful for professional workflows and delivery standards. This can be adjusted per export job.
* **Use Source Link**\
  Includes a metadata reference to the **original source file** from which the MXF OP-Atom export was created.

  > Helpful for asset tracking and relinking in post-production pipelines.
