MXF settings in Compressor
The MXF settings in Compressor appear in the Custom area of the Settings pane after you
install Pro Video Formats
for Final Cut Pro, Motion, and Compressor.
MXF (Material eXchange Format) is a metadata “wrapper” or “container” that (like
QuickTime) holds video or audio media. The metadata describes the enclosed media’s
attributes, including compression type, frame rate, frame size, creation date, and custom
data created by a camera operator, assistant, or archivist.
The MFX settings offer several compression types, including AVC-Intra, D-10/IMX,
Apple ProRes, and XDCAM HD.
Note: You can also create custom settings that use the MXF transcoding format.
The properties of MXF settings are located in the General, Video, and Audio inspectors
(described below).
