Understanding Time Information in the Track Editor
There are a variety of time-related elements that appear in the Track Editor. Some only
display time information while others allow you to change the information. The time
values help you identify the position of markers, clips, the playhead, and the pointer
within the video, audio, and subtitle streams.

Sets the start and end
time of the selected
clip with respect to
the timeline.
Timecode in the Timeline
The timeline’s timecode is continuous throughout the track. You can choose from two
sources for the timecode: zero-based and asset-based.
• Zero-based timecode: This timecode starts the timeline at 00:00:00:00. You cannot
change the zero-based timecode, and the assets assigned to the V1 stream do not
affect it.
• Asset-based timecode: This timecode can be based either on the timecode of the first
clip on the V1 stream or on a value you enter in the Track Inspector.
To choose the timeline’s timecode source
Do one of the following:
µ
Choose View > Timescale > Zero-Based Timecode or View > Timescale > Asset-Based
Timecode.
µ
Control-click in the timeline, then choose either Zero-Based Timecode or Asset-Based
Timecode from the shortcut menu.
Control-click in the
timeline to choose the
timecode source.
The pointer position, playhead, and start and end timecode values change to match the
timecode source you choose.
