Having trouble inserting or playing media because of a codec problem?
If you are having trouble inserting or playing media, it could be that you don't have the proper codec installed. For example, someone could send you a PowerPoint presentation with media based on a codec that your PC doesn't have. The best solution is for the author of the presentation to run Optimize Compatibility before sending the file to anyone else.
When attempting to insert a video file, you might receive an error message like this if you don't have the right codec file installed:

Having trouble synchronizing your music with your slide show?![]()
If your slide show is longer than one song, you can add more songs. However, if you find that you are having trouble synchronizing the music with the slide show, you can use a third-party audio editing tool, such as Audacity®to string the songs together into one file so they play continuously throughout the slide show.

What Does Codec Unavailable Mean In PowerpointWhy Codecs Are Necessary
Video and music files are huge, which means they are usually difficult to transfer over the internet. To speed up downloads, mathematical codecs were built to encode, or shrink, a signal for transmission and then decode it for viewing or editing. Without codecs, downloads of video and audio would take three to five times longer than they do now.
How Many Codecs Do I Need?
There are hundreds of codecs in use on the internet, and you will need combinations that specifically play your files.
There are codecs for audio and video compression, for streaming media over the internet, speech, video conferencing, playing MP3s, and screen capture.
To make matters more confusing, some people who share their files on the web choose to use obscure codecs to shrink their files. This frustrates users who download these files but don't know which codecs to use to play them.
If you're a regular downloader, you'll probably need 10 to 12 codecs to play all the different types of music and movies you have.
Common Codecs
Some common codecs are MP3, WMA, RealVideo, RealAudio, DivX, and XviD, but there are many others.
AVI is a common file extension you see attached to lots of video files, but it is not in itself a codec. Instead, it is a container format that many different codecs can use. Hundreds of codecs are compatible with AVI content, so it can be confusing which codecs you need to play your video files.
How Do I Know Which Codec to Download and Install?What Does Codec Missing Or Unavailable Mean
Because there are so many codec choices, codec packs are a convenient option. Codec packs are collections of codecs gathered into single files. There is debate over whether it is necessary to have a large group of codec files, but it certainly is the easiest and least frustrating option for new downloaders.

If you use Windows Media Player, it often tries to communicate to you the 4-character code of the specific codec it needs. Note this code and then visit FOURCC to obtain the missing codec. FOURCC's Samples page has some FAQs if you need more information on what's offered there.
Another option for getting codecs is to download media players that include them. Sometimes, a video or audio player installs important and common codecs when you first install the application. VLC is a great free media player that can play all sorts of file types.
