Now you will see several options for settings for your movie. The simplest thing to do is select your connection speed. Hopefully you will be selecting the third choice (DSL, cable modem, or higher) because anything slower than that means that your movie will be pretty poor quality and take a LONG time to put online.
Selecting this speed means that your movie will be saved with Windows Media Video, size 320x240 pixels, with a 4:3 aspect ratio and a framerate of 30 fps. This is one of the most common formats and will make it very easy to put your video online.
However, if you want more control over your settings, you can click the “Show more choices” button. If you want your movie to be a certain size, choose “Best fit to file size” and enter the size you want the movie to be. MovieMaker will save your file with the necessary settings to make sure it is that size.
By selecting “Other settings” you can also choose another format from the drop-down menu. If you choose this option, make sure you know what the setting means! If you’re not sure, you’re probably better off sticking with the standard option.
