Customizing the Marker Display in the Marker List
There are two display options for marker position and length in the Marker List:
View > Event Position and Length in SMPTE Units: Switches the marker position and length display between bar positions and SMPTE time positions.
View > Length as Absolute Position: Switches the marker length display between actual (relative) length and (absolute) display of the marker’s end position (shown as a bar position).
