The resolution of a TARGA image should be 720 x 480 for NTSC video or 720 x 576 for PAL. If
the original TARGA image is not of this resolution, the Image Server will attempt to re-scale it,
possibly introducing some dimensional distortion. The bit depth of the files must be 24 or 32 bit.
The Image Server does not support Targa sequences, only single frame graphics.
Animation Import
From the Image Server’s standpoint, an “animation” is a clip with a minimum length of two
seconds. Clips used in back to back seamless playback must be a minimum of four seconds long.
A separate Alpha channel may or may not be present. Any graphics workstation capable of
exporting files supported by the Image Server can make transfers to it via FTP. If an alpha channel
is present, the naming conventions of the Key/Fill Mode apply: the file name for the key video is
the same as the filename for the fill video with the addition of an underscore character ( _ ). Many
software programs have the ability to create content compatible with the Image Server , including
Final Cut Pro® 4, Avid® DV Xpress, DV/Pro, Liquid Edition, Vegas video, and Adobe® After
Effects®, Premiere® and Photoshop®.
Still Frames
A single-frame clip (a “still”) may be inserted into a playlist. The length of a still will appear as one
frame in the clip list. When a still is encountered, the playlist will pause and hold the still image
until a Play command is issued, at which point the playlist will continue to the next clip in the list.
When using the GUI, the space bar (a keyboard shortcut) will also advance the playlist. Stills may
be placed anywhere in a playlist. In fact, a playlist may be entirely composed of stills.
A still frame clip in a playlist can have a duration assigned to it (See page 60). It will then play for
that duration and the list will continue automatically.
Stills are created when TARGA files are ingested. (See page 73 for a description of TARGA file
ingest.) It is also possible to create still frames from video clips that use a 1 frame GOP (I-frame
only.) When editing the clip, make the In and Out points the same frame. This frame will be
displayed when the clip is played in the Playlist.
