When to play

The music fades out just before the time's-up sound, so the alarm is always heard. Turn this off to keep music playing on its own.

Questions

Can Google Slides show a live timer?
Not directly – Slides doesn't allow embedded web pages. A timer video (which can play automatically) or a link button are the two reliable ways.
Will the video include sound?
Yes, if you choose a time's-up sound. The sound plays at the end of the countdown, just like the live timer.
How big is the video file?
Small – about 1–2 MB per minute of countdown, in 720p.
