You have created a good PowerPoint presentation with videos and audio embedded. Everything is ready, and you are going to make your presentation before the audience. Suddenly, the audio or video file fails to play. You only get a “codec unavailable” or “media unavailable” error message on the screen. You might think that your well-prepared presentation is hence ruined. Hold on, there are some quick fixes to the PowerPoint codec unavailable issue. Read the following part and get effective methods just in case of need in the future or solve the burning problem.

What does codec unavailable mean?

The video or audio codec is software that encodes and decodes the digital video/audio data. To play a video/audio file requires the end player to have the matching codec for decoding and playing.
Codec unavailable in PowerPoint means that the program does not have the corresponding codec to decode your media, so PowerPoint cannot play the file.

1. Optimize Media Compatibility

Since the version of PowerPoint 2007, a compatibility checker is available on the Windows computer. When encountering the PowerPoint codec unavailable problem, you should first open the presentation file, then go to “File” > “Info”. If some files are incompatible with your PowerPoint, there will be a “Compatibility Mode” option. Select the option and optimize videos, audio, and other media files. Then, play the file to see whether the problem is solved.

2. Convert Video/Audio for PowerPoint

The most likely cause is the unsupported PowerPoint video codec (or audio codec).

For PowerPoint 2010, you’d better use WMV format for video files and WMA or WAV for audio files. For later versions, MP4 encoded with H.264/AAC is the recommended setting for video files, and M4A format with AAC codec is a suggested option for audio files.

Though MP4 is the recommended option for PowerPoint, there is one exception: the 32-bit version of PowerPoint 2010 can’t play MP4 and MOV files unless QuickTime for Windows is installed.

You can convert any unsupported video or audio for PowerPoint with a dedicated video converter. Refer to #part 2 for a detailed tutorial.

3. Install a Suitable Codec

The formats that different versions of PowerPoint support are varied yet limited. When you play a video or audio file in PowerPoint but the format is not well supported, you will also face codec unavailable PowerPoint 2016/2010 problems. Try to install a codec pack that can examine media files and find the codec needed for playing in PowerPoint, such as CodecInstaller.

First, close all running programs. To find the TEMP folder, click on Start > Run, or use the shortcut key combinations of Win+R; then, enter %temp% into the new Run dialog, select “OK; in the TEMP folder, select all files with a .tmp extension, and delete them. Now, restart your computer and play the file in PowerPoint again.
