Grass Valley K2 System Guide v.9.0 - Manual (Page 82)

The rules for transferring to/from a K2 Nearline SAN are as follows:
• Transfer files only. Streaming media, as in AppCenter’s Import/Send to | Stream feature, is not
supported.
• K2 media must be transferred to/from the Nearline system as a GXF or MXF file.
• Passive FTP mode is supported. You must use this mode for FTP transfers.
• In addition to FTP transfers, you can also map shared drives and use basic Windows networking
to move files to/from a Nearline storage system.
• You should use the dedicated K2 FTP/streaming network.
Additional information about Nearline FTP is as follows:
• K2 FTP protocol supports clip and bin names in non-English locales (international languages)
using UTF-8 character encoding. Refer to specifications for internationalization.
• The Nearline FTP interface operates in file mode so it does not have GXF and MXF folders to
support format-specific functionality, as does the K2 FTP interface in movie mode for “online”
K2 systems. This means the Nearline FTP interface treats all files, including GXF and MXF, as
generic files with no particular consideration for any file format.
Using reference files
When you create a simple K2 clip on a K2 system, K2 software can create a corresponding reference
file. The reference file is stored in a directory in the clip's folder on the V: drive. You can configure
the software to create QuickTime reference files, MXF reference files, or no reference files. The
following topics provide information about reference files on K2 systems.
About QuickTime reference files
The following formats are supported as QuickTime reference files:
• DV
• AVC-Intra
• XDCAM-EX
• XDCAM-HD
• XDCAM-HD 422
• IMX
The K2 clip must be a simple clip in order to create the reference file. With the QuickTime reference
file you can open the K2 clip with QuickTime tools, such as Final Cut Pro, for playback and editing.
For some formats the QuickTime tool does not provide default support, so you must configure the
tool as necessary to support the format. The QuickTime tool must be run on another system. Running
the QuickTime player or other QuickTime tools on the K2 system is not supported. You have options
for connections, access, and software to support your workflow requirements.
About MXF reference files
For MXF reference files, the K2 clip can be any supported format simple clip. K2 software creates
the MXF reference file when you create a new simple clip by recording, importing, or copying. K2
