In learning videos in the form of interviews, experts are asked about the specialist content. Expert knowledge is presented directly in this form. For example, the interviewee's "working environment" or corresponding working methods/equipment can also be presented at the same time.
In the example shown, you can see both parties in the interview. It is also possible to show only the person being interviewed and ask questions "from behind the camera".

This form is suitable for presenting specialist information at first hand. This has both psychological and emotional advantages.
