Compressing AVI files can reduce the size of the file drastically. For example, if you have an AVI video file of size 1GB, you may want to compress it into, let’s say, 500MB. When you do that, you will have more hard disk space, which means you can store more files.
You can also compress a large .AVI file such a way that it can be burned on a CD or a DVD. Even sharing videos online gets easier when the file size is small — video can be uploaded to YouTube, for instance. Here are two easy ways to reduce AVI’s file size on your Windows and Mac OS X computer.
Method 1: Compressing AVI files on Windows using Windows Movie Maker
