Debut Video Capture: record video from webcam, capture devices or screen

Debut Video Capture is a free video recording software that can capture video and audio from any USB video camera, capture device.  It can also record anything that is displayed on-screen such as a video that is playing or a user's on-screen activity.  Debut Video Capture is simple and straightforward, extremely easy to use, and It supports a wide variety of output formats and encoders. Here are more notes on this program:

• Input: you can record any input coming from a USB video input device.  You can also record both your entire screen and pre-defined rectangle area of the screen.
• Output: can output in a variety of formats, including AVI, WMV, ASF, MPG, 3PG, MP4, MOV, and FLV).
• Video resizing: you can resize the output video while recording.
• Video effects: you can apply a number of filters (black and white, negative, sepia, etc), and also have the option to change output color settings (brightness, contrast, gamma).
• Text annotation: it also supported adds on-screen text message that is present across the entire video. You can choose text's on screen placement, alignment, whether or not to use a background color, font, font-style, and font size, etc. The program also allows for variable date and/or time stamping. 
• Audio setup: an "audio setup wizard" appears when the first time the program runs,  There are two types of audio sources: internal audio and an audio input device such as a microphone. If you are not interested in the latter you can dismiss this dialog and probably not need it again (if you need to re-run it later you can).
• Hotkeys: you can define hotkeys for most program functions. This is useful when you do not want the program dialog to be visible on screen, and therefore can minimize it and control Debut using the keyboard.
• Other options: include pre-determining the recording time, sending a recorded video on completion as an email attachment, uploading to an FTP Server, recording to multiple drives, and running an external program, command based or otherwise, after recording to process the resulting file.
• Installation: please note that the installer for this program will present the option to download and install a number of other programs as well. Most of these programs are non-freeware trial versions.  If you do not know what the other programs are that are on offer I suggest you not install them.
