Bandicam is a screen capture utility developed by South Korean software company Bandisoft that can take screenshots or record screen changes. Bandicam consists of three modes. One is the 'Rectangle on a screen' mode, which can be used for recording a certain area on the PC screen. The other is the 'DirectX/OpenGL window' mode, which can record the target created in DirectX or OpenGL. And the last is HDMI Device recording mode which records webcam and HDMI devices.
Bandicam displays a FPS count in the corner of the screen while it is active in the 'DirectX/OpenGL window' mode. When the FPS count is shown in green, it means the program is ready to record, and when it starts recording, it changes the color of the FPS count to red. The FPS count is not displayed when the program is recording in the 'Rectangle on a screen' mode.
Bandicam is a shareware, meaning that it can be tested free of charge for a limited period of time. During trial period, Bandicam places its name as a watermark at the top of every recorded video or screenshot, and each recorded video is limited to 10 minutes in length. However users can adjust the screen margin with the video screen so that the watermark is off screen from the video.
Bandicam can record video at resolutions up to 2560×1600 in size. As Bandicam supports AVI 2.0 OpenDML extensions, the maximum clip size is unlimited as long as the local Hard Disk has free space available.
It supports hardware acceleration through OpenGL, Nvidia NVENC, AMD APP and QuickSync.
