FTP File Transfers
For standard FTP transfers, the Image Server will recognize the following file formats:
TARGA (.tga)
During transfer, the Image Server will split the TARGA file into a Fill frame and a Key (alpha)
frame. These two frames will each be converted to MPEG-2 files, one frame in length.
See “Importing TARGA Graphic Files” (above) and “Key/Fill Mode” (below) for additional
information.
DV Stream (.dv)
These are ‘elementary’ DV files containing a single stream of multiplexed audio and video.
The Image Server will recognize and maintain .dv extensions on DV stream files, allowing
transfer of .dv files between Image Servers and graphics workstations without modification.
Only audio at 48K, 16-bit is supported.
AVI Files (.avi)
An AVI file is a container that encapsulates and describes a type of interleaved audio and
video. The Image Server will import Type 1 .avi files (a single stream of multiplexed audio and
video) containing DV format video and 48K uncompressed audio. During ingest of .avi files,
the server will convert the file into a DV stream (.dv) for storage and future transfer.
MPEG-2 (.mp2, mpg, mpeg, m2v)
The Image Server will ingest valid MPEG-2 program streams or elementary streams. The
server’s ingest application will recognize a program stream that encapsulates a single MPEG-2
video stream, and up to 2 stereo pairs of 16- or 24-bit, 48kHz, uncompressed audio. 16-bit
audio files will be written into a 24-bit space.
MXF - Material Exchange Format (.mxf)
Transfer of MXF files between compatible products will be the preferred method of file
interchange to-and-from an Image Server. 360 Systems supports ingest and playout of MPEG-2
files based on SMPTE 377M, 378M and SMPTE 381M, Operational Patterns 1a and 1b.
Key/Fill Mode
When the “Gang to Ch2” box is selected in the Channel 3 transport control window, then a
pair of key and fill channels will be ganged and played together. Transport operations on
Channel 2 will control both Channel 2 and Channel 3. This allows the server to play locked,
frame-accurate key and fill material (either stills or clips) on Channels 2 and 3. Only a single
channel of an automation controller is needed to play both the key and the fill.
