It's only a myth that you need expensive video editors for video editing tasks like adding scrolling texts, subtitles or custom animations - you will find such features even inside free video editors that we discuss here to help you produce video podcasts, home movies and online web video easily.
But before that, do check the installation DVD that came with your handycam or digital camera - most camera vendors like Sony, Canon and Panasonic generally provide a decent video editing software with the camera. If that doesn't help, here's a list of best and free video editing software:
Windows Movie Maker - The best video editing tool for Windows that's absolutely free and chances are you already have it installed on your computer as part of XP SP2. Microsoft Movie Maker has all the basic video editing tools plus a good collection of transitions and video effects.
There's an in-built movie titler that lets add you styles to text titles including ticker taps, zoom and even the scroll effect. And if you are feeling lazy, just hit the AutoMovie command to have the entire video produced for you with intervention.
