OP1a

Export Tagging Options

• Tag All H.264 Exports as ‘High Unconstrained’ When enabled, all generic H.264 video exports within MXF OP1a files will be tagged using the widely supported 'High Unconstrained' profile.

  If disabled, the export will attempt to use the specific H.264 profile based on the encode settings, which may offer more precision but less compatibility.

• Use MCA Audio Labels When enabled, audio channels in MXF OP1a exports will be tagged with descriptive MCA labels (e.g., Front Left, Front Right, Center, LFE).

  Useful for professional delivery specs. Can be toggled per job in the Export panel.
