Exports MP4chaps of all markers except xruns. The markers are stored in the
|
|
export directory of the session in mp4 chapter marks format. The filename
|
|
is mp4chaps.txt
|
|
|
|
Note that there's always a chapter mark "Intro" at 00:00:00.000 as some
|
|
players can't live without it. If there are no exportable markers, the file
|
|
is not created.
|
|
|
|
This is a bit more convenient than the export option, as one does not
|
|
have to wait for the export.
