While watching a video in a Web site, you may sometimes want to save the video into your local drive, and then play it offline later. This utility allows you to capture .flv (Flash Video) files and RTSP/MMS video streams while the Web browser download and play them inside a Web page. After the entire video file is downloaded and played by the Web browser, the video file is saved in the folder that you selected, and you can play it offline later with any Video player.
Using WebVideoCap
WebVideoCap doesn't require any installation process or additional DLL files. In order to start using it, simply run the executable file - WebVideoCap.exe
(However, if you have Vista with SP1, you have to download and install the WinPcap driver)
After you run it, the main window of WebVideoCap is displayed. First, you have to select the folder that you want to save the captured video files. By default, the save folder is located in the 'files' folder under the folder of the executable file. If you have more than one network or dialup adapter, you should also select the right adapter.
After that, you can click the 'Start Capture' button. While WebVideoCap is in capture mode, open your browser in a video Web page. If everything goes right, you should see a new video file created and grown inside the folder that you have selected. You can continue watching more Web site videos while WebVideoCap capture the video files in the background. After you finish, click the 'Stop Capture' button.
