一个屏幕摄像工具。它可以捕获屏幕上你所进行的操作，保存为标准的 AVI 视频文件，可以记录系统扬声器所发出的声音，可以通过麦克风录制声音。

你可以自定义捕获的区域、捕获的速度、声音的采样率、鼠标指针的形状效果等，你还可以让 CamStudio 自动拍摄。这是一个相当有用的工具，可以用于创建软件的演示，开发训练和辅导的视频等等。

更新日志：

Camstudio v2.6, release 248:
------------------------------
Add Xnote time stamp option to effects.
This option adds a delayed stopwatch in the capture.
Recordings will shows a stopwatch annotation (in milli seconds). To get displayed stopwatch  time in sync with the image from the camera user can define number of milli seconds that camera is behind real events.
Although captured time for events as reported by Xnote stopwatch is accurate a small shift due to inaccuracy in estimated delay is always applicable.
For average user this will be not an mayor issue.

Camstudio recording can be set on pause. If Xnote snap event occurs recording will continue automatically.

Camstudio v2.6, release 250:
------------------------------
Camstudio will show snap times and running time if Xnote timestamp annotation is applicable.

BTW.
Current delaytime can be changed by the user.
With this release we have a small problem with storage of defined Xnote-Timestamp settings.
You can change settings but although saved we have a problem reloaded previously setting.
