Selecting one of the three sub menu items allows you to change the time system
in which the timecodes in The Frame List are displayed.
/1000 Sec
This timecode setting displays the timecode for every frame in milliseconds.
HH:MM:SS:MS
The timecodes will be displayed as time offsets of the frames relative to the
beginning of the project in hours, minutes, seconds and milliseconds. The head
of the timecode column will display the time of the whole project.
HH:MM:SS.FF
In contrast to the first two settings, this setting is based on a frames per
second basis. The timecodes are, again, treated as offsets. First, MainActor
will determine the global frames per second rate of the project. Then it will
display the timecodes, based on this fps rate, in hours, minutes, seconds and the
frame offset. The frame offset is between 0 (the first frame of the second) and
the frames per second rate minus one (the last frame of the second). The head
of the timecode column will display the time of the whole project.
