DV Stream (.dv)
The Image Server recognizes DV25 (25 Mb/s) stream files containing multiplexed video and audio
according to SMPTE 314M. The audio must be 48 KHz sample rate locked to video. The .dv file
extension is maintained, allowing transfer of .dv files between Image Servers and graphic
workstations without modification. DV50 is not supported.
AVI Files in DV format (.avi)
An AVI file is a container that encapsulates a wide range of audio and video formats. The Image
Server can recognize only DV AVI Type 1 and Type 2. Type 1 .avi files contain a single stream of
multiplexed audio and DV25 format video as described above. Type 2 .avi files contain separate
audio and video (even though the video may contain the same or different audio interleaved.)
During ingest of .avi files, the server will convert the file into a DV stream (.dv) for storage and
future FTP transfer. When the resulting .dv file is exported, if it was originally a type 2 it will
contain the .avi audio, not any audio that may have been present in the DV video stream.
MPEG-2 Program Stream (.mpg, .std)
Standard-definition MPEG-2 program streams containing up to 2 stereo pairs of 16-bit, 48K, MPEG2
Layer 1 audio are supported. 16-bit audio files will be written into a 24-bit space.
TARGA (.tga)
24 or 32 bit format (16 bit format is not supported.) During transfer, the TARGA file will be split into
a Fill frame and a Key (Alpha) frame. These are saved as two separate MPEG-2 clips, each one
frame in length. The clip name for the fill frame is the base name of the .tga file, while the key
frame has this name with an appended underscore character. The resulting files will be available as
MXF files for subsequent FTP transfer.
PES – Packetized MPEG-2 Elementary Stream (.mp2, .m2v)
The Image Server will accept MPEG-2 standard-definition elementary stream files. These contain
video-only, no audio.
Wave (.wav) or Wave-64 (.w64)
The Image Server will accept WAVE or WAVE-64 files containing only audio. Audio files should
contain 24-bit stereo pairs sampled at 48 KHz. The resulting audio-only clips are available for play
out, but do not appear in the FTP directory listing for subsequent transfers.
Playlists (.lst, .txt)
An Image Server play list is a text-based file residing in the /lists directory. Play lists can be created
off-line and transferred to the Image Server using FTP. See page 118 for further information on
Playlist file editing and management.
As-Run Logs (.arl)
As-Run logs are available from FTP to confirm the operation of the Image Server Advanced Playlist
feature. See page 114 for further information on using As-Run logs.
