You can enabled video recording in BlackBerry via BlackBerry 4.3 (or later) OS update that can be downloaded for free from the Internet.
To begin recording video on your BlackBerry, open the video camera by selecting the video icon on your BlackBerry home screen (it’s in the shape of a camcorder).
The process of recording is same as capturing a photo with your BlackBerry Camera. Click the trackball (or pearl) to start the capture and click the same button to pause capturing. Move the highlighter with the trackball over the square icon to stop the recording.
You may also roll the trackball up or down to zoom in or out from a subject before video capture. You can turn on the video light incase you are capturing video in a low-light situation (like inside the room).
You can transfer video from the BlackBerry to your computer using the USB cable or via Bluetooth or send it to a contact as an MMS.
Video recording is available for BlackBerry Curve, BlackBerry Peal, BlackBerry Bold and BlackBerry Storm.
