Chronos

Measure timeframes

1. Adding a chronometer

Click on the Chronometer button of the drawings tool bar :

Click anywhere on the image to add the chronometer.

The chronometer will be visible from this frame forward.
You can change background color and font size through the configuration dialog box.

2. Measuring a timeframe

As long as you do not start the count, the chronometer displays zero.

Note: The time representation used is depending on Kinovea's configuration.
To learn more about the various time representations formats, check Preferences.

To measure the duration of an event, move to the start of the event, use the context menu Start Chronometer.
Move to the end of the event and use the context menu Stop Chronometer.

The last value displayed on the chronometer represent the event duration.
This value stays visible after the chronometer has stopped.

If after the measure you would like to hide the chronometer without completely removing it, use the Hide Chronometer menu.
The chronometer will then be only visible between the frame you added it and this last frame.

3. Identifying chronometers with labels

When you add several chronometers to measure simultaneous events, it is interesting to be able to identify easily which timed value is associated to any given chronometer.
A first approach is to use color coding and various sizes for chronometers.

To identify with no doubt each chronometer fill its Label property in the configuration dialog.
A label can be a simple descriptive word, a numeral identifier or any other string.
