AirSpeed 5000 MXF OP1A Files
In AirSpeed 5000, the transfer of media via FTP is performed by using MXF wrapped (OP1A)
files. These files follow the OP1A pattern as specified in SMPTE Specification #378M.
This means all media (i.e., video, audio, data tracks) is wrapped in an MXF OP1A file. The
wrapped media must conform to the operational points supported by the AirSpeed 5000.
Currently, AirSpeed 5000 generates MXF files in which the audio is formatted in stereo pairs.
We support a maximum of four (4) pairs of audio for SD formats, and eight (8) pairs of audio for
HD formats. The consumer of files we generate must support audio formatted in stereo pairs. If
you send clips to the AirSpeed 5000, we support mono, stereo pairs and Broadcast .wav. If you
have a source .mxf file with mono audio, transfer it to AirSpeed 5000, and then re-transfer that
clip back to another location via FTP, the new file will be rewrapped as a stereo pair. Because of
the rewrapping involved in the MXF rewrapping process, file sizes might be different. However,
the actual clip duration and content should not change.
