Compatible multimedia file formats

The tables below show the audio and video file formats that you can use in Microsoft Office PowerPoint 2007. If you do not see a file format listed below, you will not be able to play the sound or movie file in a PowerPoint 2007 presentation unless you first convert the file to a supported file format. You can convert your file to a supported file format by using programs, utilities, or add-ins, other than PowerPoint 2007, such as the following:

  • Microsoft Windows Media Encoder     Windows Media Encoder is a free program that makes some files compatible with PowerPoint 2007. For more information, see Microsoft Windows Media Encoder.

Important: Although your sound or video file may have the same file extension as one listed below, it may not play correctly if the correct version of the codec is not installed, or if the file is not encoded in a format that is recognized by your version of Microsoft Windows. Encoding is the process of converting data into a stream of ones and zeros. For more information about the most common codecs, including where to get them, see Encoding Audio and Video with Windows Media Codecs or Using codecs.
