Numbers
Edit video and audio in Numbers on Mac
By default, a video or audio file plays one time when you click the Play button . You can set it to repeat in a loop, adjust its volume, and trim it to play only part of the video or audio. For a video, you can change the poster frame that’s displayed on a sheet to represent the video.
You can set Numbers to optimize the format and quality of movies and images that you add to spreadsheets.
