Instance Movie Timer
In every instance movie window, the time can be reset to zero at the playhead location, so time in the movie can be measured from any point.
3. Drag the playhead or play the movie to measure a period of time past this new zero point. The time that presented in blue is the elapsed time from the new zero origin point.
4. Drag the playhead prior to the new time origin point and the font color will change to red indicating negative time or the playhead is located before the new origin.
