I think both types of videos have their advantages, but the real difference depends on the audience and the purpose of the content. Short videos are good for grabbing people's attention and reaching new viewers, while longer videos can provide more opportunities to build trust and drive interested viewers to the website. In my personal opinion, short videos should be used to grab people's attention and longer videos should be used to provide useful information and direct viewers to relevant pages on the website. The real issue is not the length of the video, but its usefulness.
