Zoom in / out of the Histogram
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 selected section will ll to the extent of the current histogram as shown below.
For more functions of the playback control buttons, please refer to page 164 for detailed description.
