BT Video Wizard is a utility that records from any video capture source to WMV format. WMV format is the native format used by Windows Media Player for video. WMV format is highly compressed creating great videos in a small file size. This makes BT Video Wizard an excellent choice for recording video email attachments, or for placing videos on the web. Use your web cam to create a 10 minute video of your kids playing to send to Grandma in an email. You can do it in about 300K rather than 50 megabits!
