Add existing video and audio in Pages on Mac
You can add video and audio to a document, or replace a media placeholder with a video.
Note: Video and audio files must be in a format that QuickTime supports on your Mac. If you can’t add or play a video or audio file, try using iMovie, QuickTime Player, or Compressor to convert the file to an MPEG-4 file (with a .m4a filename extension) for audio, or a QuickTime file (with a .mov filename extension) for video.
You can also record audio and add it to your document.
