The main difference is the file compression. MPEG is an old format, but is the most widely used and can be viewed on both PCs and Macs, however the file size is much larger than the other formats. MPEG4 is a modern format, but you’ll need to download a new movie player such as the latest version of Quicktime from www.quicktime.com or Winamp from www.winamp.com. The file compression is extremely good while still maintaining good quality video. Older computers may have trouble viewing this format and as a result, the picture may be “jumpy” on such systems. WMV also has better compression than the MPEG format. Anyone running a Windows PC using Windows Media Player is able to view this format. If you’re a Mac user and would like to use the WMV format, download and install the free movie player Flip4Mac at www.flip4mac.com.
