The edit decision list (EDL) system allows you to automatically skip
|
|
|
|
|
or mute sections of videos during playback, based on a movie specific
|
|
|
|
|
EDL configuration file.

This is useful for those who may want to watch a film in "family-friendly"
|
|
|
|
|
mode. You can cut out any violence, profanity, Jar-Jar Binks .. from a movie
|
|
|
|
|
according to your own personal preferences. Aside from this, there are other
|
|
|
|
|
uses, like automatically skipping over commercials in video files you watch.

The EDL file format is pretty bare-bones. Once the EDL system has reached a
|
|
|
|
|
certain level of maturity, an XML-based file format will probably be implemented
|
|
|
|
|
(keeping backwards compatibility with previous EDL formats).

The maximum number of EDL entries for the current incarnation of EDL is 1000.
|
|
|
|
|
If you happen to need more, change the <systemitem>#define MAX_EDL_ENTRIES</systemitem>
|
|
|
|
|
in the <filename>edl.h</filename> file.

The current EDL file format is:
|
|
|
|
|
<programlisting>
|
|
|
|
|
[begin second] [end second] [action]
|
|
|
|
|
</programlisting>
|
|
|
|
|
Where the seconds are floating-point numbers and the action is either
|
|
|
|
|
<literal>0</literal> for skip or <literal>1</literal> for mute. Example:
|
|
|
|
|
<programlisting>
|
|
|
|
|
5.3 7.1 0
|
|
|
|
|
15 16.7 1
|
|
|
|
|
420 422 0
|
|
|
|
|
</programlisting>
|
|
|
|
|
This will skip from second 5.3 to second 7.1 of the video, then mute at
|
|
|
|
|
15 seconds, unmute at 16.7 seconds and skip from second 420 to second 422
|
|
|
|
|
of the video. These actions will be performed when the playback timer
|
|
|
|
|
reaches the times given in the file.

|
|
To create an EDL file to work from, use the <option>-edlout <filename></option>
|
|
|
|
|
flag. During playback, when you want to mark the previous two seconds to skip over,
|
|
|
|
|
hit <keycap>i</keycap>. A corresponding entry will be written to the file for
|
|
|
|
|
that time. You can then go back and fine-tune the generated EDL file.
