As the second capture shows, by clicking 

Histogram Zoom In, the total time of the histogram will 

shorten to half of the original period of time, while the red part of the histogram that shows the period of 

time of the video clip will extend to twice the original time span.

In addition to clicking 

 and 

 to zoom in/ out of the histogram, you can use the mouse directly to 

drag the histogram to zoom in part of the focused video clip.

For example:
a. Drag a section of the histogram. You can drag it to either direction.

b. The section will be extended as shown below.
