Numbers
Add video and audio in Numbers on iPad
You can add video and audio to a spreadsheet, or replace a media placeholder with a video.
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 a QuickTime file (with a .mov filename extension) for video, or an MPEG-4 file (with a .m4a filename extension) for audio.
You can also record video and audio and add it to your spreadsheet.
To set video or audio looping or adjust playback volume, see Edit video and audio.
