What is the primary characteristic of static videos in training modules?

Static videos are primarily characterized by the lack of interaction with the viewer. This means that once the video is played, users cannot engage with the content through any interactive elements, such as quizzes, clickable segments, or real-time feedback. The viewer's experience is generally passive, where they consume the information presented without opportunities to influence the content or test their understanding during the presentation.

In contrast, other characteristics associated with training modules do not apply to static videos. High interactivity is typically linked to dynamic learning tools or gamified content that allows learners to participate actively. The notion of requiring multiple sessions usually refers to more extensive or complex training that might necessitate revisiting material over time, which is not a feature inherent to static videos. Lastly, while video production can varying in cost, static videos themselves do not have a defining characteristic of being expensive; costs can be associated with many factors, including technology, expertise, and the complexity of the content being delivered.
