How does a warm-up video lead to a countdown?

There are two ways to elicit a countdown in a warm-up video:

1. Set a timer or countdown timer in the preheating video to let the audience see the passage of time, thus leading to the countdown. This way can make the audience feel the sense of urgency of time more intuitively and enhance the sense of expectation.

2. Advance the upcoming activities or contents in the preheating video, inform the start time, and then count down. This way can let the audience know the upcoming content in advance, increase their expectation and interest, and at the same time, the countdown can remind the audience to pay attention to the time and avoid missing the event.

The purpose of countdown is to create a sense of urgency and expectation, and enhance the audience's sense of participation and experience. In practical application, we need to consider the length, frequency and mode of countdown, and choose the appropriate mode according to different activities and occasions to achieve the best effect.
