By using time restrictions for the questions in an interactive video, you can draw the attention of the viewers and provide a challenge as a gamification element. Let's get started.

Firstly, add a question to the video. Drag and drop the Countdown widget in the Element panel to the same time interval with the question. After making the general adjustments from the properties panel of the Countdown tool, click the On Complete property. Your selection of the features in this list varies according to your case. For example, when we give 5 seconds to count down time and the user expires this time before answering the question, you have to choose what will happen from this list. You can find the most used features in the list and the most common use cases:

Jump in This Project: If the viewer does not answer the question in the required time, you can automatically direct it to any time of the video.

Set Visible: You can make a warning with audio. Make invisible audio that you have added to the same time interval from its Properties area. Then, in the Properties area of the Countdown tool, click On Complete and select Play Audio. Then, select the audio. For example, you can make a warning such as; "Your time is up, please, make a choice" or "You couldn't answer the question in the time given to you, please watch the relevant Section again". Also, you can add a new On Complete feature, select Jump to and redirect the video to the relevant section.

Set Variable: If the audience does not answer, you can automatically define a variable, assign values to the questions that they didn’t answer. Then, you can show the number of such questions at the end of the video. You can read this article to see how variables are used in the video.
