OP1a

Tag all H264 Exports as 'High Unconstrained' - If checked, MXF OP1a Files will tag any generic H264 as 'High Unconstrained' which is widely supported, if unchecked it will attempt to tag generic H264 exports with its specific type.

Use MCA Audio Labels - If checked, MXF OP1a Files will tag audio channels with their correct descriptors such as Front Left, Front Right, etc. This can be changed in a specific export job.
