Working with the Media Watcher
number of loops, together with the full in- and out-sections, in a time that exactly matches the
duration, it plays just as many full loops as it can before the out-section. Because of this, an
animation may play for slightly less time than its specified duration.
For the complex mode, you need to include a modified mode.txt file in the archive. In this file,
you start with the command "ANIMATE"; you then specify the start and end frames for each
section.
Example:
ANIMATE
IN_START 1
IN_END 75
LOOP_START 76
LOOP_END 175
OUT_START 176
OUT_END 250
For an animation in which all the frames after the first section are looped, you only need to
specify the start of the loop:
ANIMATE
LOOP_START 76
An operator can schedule animated sequences from the Logo palette, which appears in the
Content Selector on the Channel Control layout.
Importing a single TARGA frame for use as a logo
The Media Watcher can import a single TARGA frame in the same way it imports animated
sequences.
You need to place a .tzip file containing the TARGA frame in the Inbox; the .tzip file should also
include a mode.txt file specifying the Freeze playout mode.
See the previous topic, "Animated sequences and their different playout modes".
Registering of reference MOV and MXF files
For the Media Watcher to register reference MOV and MXF files, you create a custom folder,
"_ESSENCE", and a subfolder, "media.dir", in the Inbox.
The video and audio essence files, along with any associated .scc or .stl file containing the
external subtitle (closed-caption) data, are placed in the media.dir subfolder. After this, the
reference file is placed in the _ESSENCE subfolder of the Inbox.
The Media Watcher registers the reference file and moves it to a folder depending on the
media type and the date on which it performs the task. The folder sequence is: clip storage
format (e.g. MXF); current year; today's date (US format).
On registering the essence files, the Media Watcher moves the files into the essence subfolder
of the date subfolder, named according to the filename followed by "_OMN", a 10 digit number
and "_ESSENCE".
