Media File
The Media File parameter lets you identify which Stock or User media file to apply (map) as a
texture on the selected 3-D object. You can supplement the large library of Stock video loops
and still images with Custom files. This parameter selects media files from within the folder
defined by the Media Folder parameter.
For a reference of media files available as stock content with your DL.2 fixture, go to the link for
the Stock Content Guide on
http://www.highend.com/support/digital_lighting/
dl2supportguide/ . You can also view thumbnail images of media files in the CMA, (see Viewing
Files on page 132.
Default DMX Value: 0 = No file selected
Tip: You can preview a visual display of the media files loaded on a DL.2
fixture in the Content Management Application’s thumbnails view,
(see Viewing Content on page 131) or in the File Tab of a DL.2 fixture
menu display (see File Screen on page 30).
Defining a Media File Segment
You can define any portion of a video media file to play using the In Frame and Out Frame
parameters. By default, the In Frame is the beginning of the media file and the Out Frame is the
end of the file. Media files can have different lengths.
In Frame and Out Frame Parameters
You can select any segment of a media file for playback by assigning an In Frame value as a
start point and an Out Frame as an end point.
Note: DMX parameter values for these parameters do not correspond to a
particular “frame”. They are defined as a percentage of the movie length.
This makes it possible to create segments with an Out Frame preceding
the In Frame and simplifies playback synchronization between media files.
The In Frame parameter corresponds to a 16-bit DMX value equal to a starting point for the
playback segment of the selected file. The Out Frame parameter corresponds to a 16-bit DMX
value equal to an end point for the playback segment of the selected media file.
Assigning the In Frame and Out Frame parameters to default DMX values will playback the
entire movie file. Choosing other settings are useful when you want to:
• begin or end a media file at any point other than the default
• start or stop on a specific image
• you need to shorten the media file to a specific length
