Transfer of Edited Segments
The Image Server sets MARK-IN and MARK-OUT points in a clip as “edit pointers.” For all edit
operations within a given Image Server, these pointers produce “virtual edits” that save disk space,
and the time it would take to re-write the marked region as a new file.
It is clearly impractical to transfer a long file to obtain a 30-second virtual clip marked within it.
Therefore, the Image Server transfers only the region between In/Out points, and not the entire file.
If you want to transfer the entire recording, be sure that the In/Out markers are set to the beginning
and end of material before the transfer.
To maintain the identity of the transferred clip, the time code references for its Mark-In/Out points
are maintained, as shown in Figure 31. (Note that DV files do not contain a start time, so all
segments of edited DV format clips will start at 00:00:00 after being transferred.)
When transferring edited material, keep in mind that you are making copies of the data on the target
device. While subclips that reference the same video content on the original recordings take up
minimal extra disk space, they could take considerably more space on the target storage.

Supported file types
MAXX 6T recognizes media file types by their file extension. It is important that the file extension
properly identifies the file content. Attempts to send a file in one format but masquerading as
another due to a wrong file extension may result in undefined behavior. The following formats are
supported:
MXF - Material Exchange Format (.mxf)
The Image Server supports FTP import and export of MPEG-2 files in MXF format conforming to
operational pattern 1A. The video essence must be a standard-definition (NTSC or PAL) MPEG-2
elementary stream, including D10. The audio essence must contain 16 or 24 bit samples, sampled
at 48000Hz, organized as a single track containing 1, 2 or 4 audio channels. Applicable standards
are SMPTE 377M, 378M and 381M.
