PowerPoint supports a number of common audio and video formats. We'll go through the details and show you how to incorporate audio and video files into your presentation glasses.
Audio formats supported in PowerPoint
The current versions of PowerPoint support the following audio formats .wav, .mp3., .Wma, .midi, .aiff, and .au .
first Wav files are uncompressed audio files, which means they are large in file size, but they are also the best quality sound.
2nd The MP3 format (most popular) is a compressed audio sequence that is only a fraction (about 8 percent) of the original recording size, but still suitable for playback on CDs and DVDs or PowerPoint slideshows.
3rd Windows Media Audio (WMA) files are MP3's biggest competitor. They are simply streamed, making them a popular choice for websites.
4th Musical Instrument Digital Interface (MIDI) files have been designed for recording, editing and listening to your digital synthesizer compositions.
5th AIFF (Audio Interchange File Format) is Apple's audio file format. The files are larger than MP3 files (about 10 MB per minute audio) and are still used for audio recording when original data is needed in an uncompressed format.
6th And most recently, the AU audio format, introduced by Sun Microsystems, was used by some of the older systems such as Sun, other various Unix-based machines, Adobe Audition and QuickTime.
NOTE: RealAudio (.ra) files are not directly compatible with PowerPoint. You can convert them to an MP3 format with a free program called Zamzar.
Video file formats supported in PowerPoint
PowerPoint supports these video formats: .avi, .mpg, and .mpeg .
first Audio Video Interleave (AVI) files are video formats created by Microsoft, which store both video and audio data. These files are compatible with Windows Media Player, Microsoft Movies & TV and Apple QuickTime Player. Because they are bundled with each operating system, your computer standardizes these formats when you try to play an AVI file.
2. Video Format MPG and MPEG (Moving Picture Experts Group) are compressed movie files used for Internet distribution. Current MPEG variations include MPEG-1, MPEG-2, MPEG-3, MPEG-4, MPEG-7 and MPEG-21, and are much better than the competition.
NOTE: QuickTime movies (.mov) and RealVideo (.ram or .rv) are not directly compatible with PowerPoint. You can convert them to an MPG format using one of the many video converter programs like iSkysoft Video Converter Ultimate.
