Fix your media file that won't play in PowerPoint.
For a complete list of supported video formats, see Video and audio file formats supported in PowerPoint.
Recommendations
Video: We recommend that you use .mp4 files encoded with H.264 video (also known as MPEG-4 AVC) and AAC audio. This is your best bet for compatibility across both Windows and Mac versions of PowerPoint.
Audio: We recommend that you use .m4a files encoded with AAC audio.
These names and formats sound complicated, but you can easily convert to and use these formats without having to know anything more than those names.
If PowerPoint doesn’t let you insert a video or audio file, convert it to the recommended format.
Missing codec?
If your media file is in a supported format, but won't play in PowerPoint, then you can either add a missing codec to your PC (described in the procedure below) or convert the media file to the recommended format. Converting your media file is easier than solving an individual codec mystery.
A codec is a small piece of software that decodes a digital media file so that it can be played as sound or video.
It's not easy to determine which codec you need for your media file. One solution is to install a package of numerous codecs on your computer. That greatly increases the likelihood that you'll have the necessary codec to play your the audio or video file that is giving you a problem. Follow the steps below to install a package of codecs on your PC.
