Add existing video and audio in Keynote on iPad
You can add video and audio to a slide. When you show the slide during a presentation, by default the video or audio plays when you tap anywhere on the slide. You can set video or audio looping and start timing to make the video or audio start automatically when the slide appears. You can also add a soundtrack that plays for the entire presentation.
Note: Video and audio files must be in a format that QuickTime supports on your device. If you can’t add or play a media file, try using iMovie, QuickTime Player or Compressor on a Mac 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 video and audio and add it to your presentation.
