===== Screen Recording =====
Often times you may wish to record AUT as it's being tested.  //Screen Recording// allows you to record the screenshot of AUT while the model is executing programmatically in MScript.  The recorded screenshots of the AUT can be archived and played back after the model execution.

Be aware that screen recording can generate lots of screenshots which can take up a lot of disk space.

----
==== Playback ====

Screen recordings can be played back through //File / Playback// (details see [[playback | Playback Screen Recording]]).


==== Start / Stop Screen Recording ====
Screen recording is a global setting.  You must enable it to start the screen recording and the screen recording will continue until it is explicitly disabled/stopped or until //TestOptimal Server// is restarted.

By default, screen recording is disabled. You can enable screen recording by calling MScript function [[http://testoptimal.com/javaDoc/reference/com/webmbt/plugin/MbtScriptExecutor.html#startScreenRecording(java.lang.String)| $startScreenRecording('name')]].

To stop screen recording, call MScript function [[http://testoptimal.com/javaDoc/reference/com/webmbt/plugin/MbtScriptExecutor.html#stopScreenRecording() | $stopScreenRecording()]].

You will usually place //$startScreenRecording('name')// in //MBT_Start// trigger and //$stopScreenRecording()// in //MBT_end// trigger.

==== Control Recording Interval ====

By default, AUT snapshot is taken every 200 milliseconds.  You may adjust this interval by calling MScript function [[http://testoptimal.com/javaDoc/reference/com/webmbt/plugin/MbtScriptExecutor.html#setRecordingInerval(java.lang.String) | $setScreenRecordingInterval('number of milliseconds')]].

This setting is global and will remain in effect until //$setScreenRecordingInterval('millis')// is called again with a new value or until //TestOptimal Server// is restarted.

==== File Location ====
AUT screenshot image files are stored in a folder in //video// folder.

You may delete a specific video folder. But be sure to leave //Default// folder alone as it's used by the system.
