Windows Movie Maker includes subtitles as an option in the built in title tool. The disadvantage is the software only allows you to add on title per clip, so a dialogue intense movie needs to be broken into many small clips in order to get subtitles matched up with every verbal exchange. The other disadvantage is very little control over where the subtitles appear on screen. The only option is at the bottom of the screen with either one or two lines of text.
To create a subtitle in Windows Movie Maker, select the movie clip on the timeline by clicking on it and choose Tools > Titles and Credits from the menu. Choose the option to Add title on the selected clip in the timeline.
Type in your title text in the empty box provided and click Change the title animation. Find the Subtitle option in the list of choices. The last thing to do is adjust the color (and possibly the font) of your subtitle. The default color for titles in Windows Movie Maker is white, which is almost impossible to read in light colored sections of your movie sequence. As someone who watches many films from Korea and China, I know reading subtitles on screen is much easier is the color is a shade of yellow. Click on Change the font text and color and make selections to fit your needs.
Repeat these steps for each of the clips in your movie.
