Content Selection - In-Frame and Out-
Frame
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
In Frame Default DMX Value: 0 = The beginning of a media file is the playback start point.
Out Frame Default DMX Value: 65535 = The end of a media file is the playback endpoint.
As you move from 0 to 100% of the In Frame value range, you can select the beginning of a media file segment as a
percentage of the file length. Moving from 0 to 100% of the Out Frame value range selects the end of a media file
segment as a percentage of the file length.
Segment Selection Examples
You can create a segment anywhere between the beginning and the end of a media file. The In Frame does not have to
precede the Out Frame.
To skip a segment in the center of a media file, set the In Frame to a point following the Out Frame. The file will play from
the In Frame to the end and then start at the beginning of the file and play to the Out Frame. When you create a segment
in this way, you may notice a jump as playback skips from the end of the file to the beginning.
