long GoP is not supported.

MXF export behavior on K2 systems

Upon MXF export the K2 system checks media for speci cations as they apply to industry standard
formats such as XDCAM and eVTR style D10AES3. If speci cations match, the media is exported
as the appropriate format.
The K2 system allows you to alter clips so that they no longer match the speci cations for the
industry-standard format. For example, you can add audio tracks to exceed the # of Audio Tracks
speci cation. If you alter a clip in this way, on MXF export the K2 system exports the clip but it is
not compatible with the industry-standard format.
