From the developer:
AVRecorder is a utility for recording video from your computer screen and creating screenshots. The application allows you to record a full screen or selected part. Moreover, AVRecorder allows you to adjust the video quality (high, medium, or low) and enables you to modify the FPS (frame per second) rate and create screenshot.
