This research examines the key audiovisual elements contributing to a high number of views (over 100,000) for French-language popular science videos on YouTube. Analyzing 210 videos, the study identifies five main factors: topic choice, timing and duration of on-screen elements, use of auditory and visual elements, the host's on-screen presence to interact with the audience, and availability of the video in 1080p resolution or higher. The findings suggest that YouTubers should choose accessible topics, use captivating visuals and audio elements to maintain viewers' attention, show themselves on screen to create a connection, and adopt dynamic editing to improve attention retention over an extended period.
This article explores the evolution of popular science videos, tracing their development from the first printed scientific works to the rise of online video platforms.

This article explores the sociological aspects relevant to the creation of popular science videos on platforms such as YouTube. It focuses on two key areas: social influence and media effects. The first section examines how YouTubers use strategies such as resemblance, credibility, consistency, and emotional engagement to influence their audiences. It also highlights the importance of shaping their image and message to build viewer trust and loyalty. The second section analyzes broader media effects, detailing how exposure to videos can influence viewer beliefs, attitudes, and behaviors. Furthermore, it considers the role of social representation in the media, where YouTubers help shape social perceptions and reinforce or modify stereotypes. The article concludes by highlighting the ethical responsibilities of content creators in managing their influence and media representation.
This thesis explores acoustic considerations and audiovisual equipment for a medium-sized video recording studio, fitted out in an existing room with a budget of €80,000. It examines acoustic treatment methods (absorption, diffusion, isolation) and the equipment required for professional audiovisual production.
A studio was created in an office building in Amsterdam, consisting of a control room and a broadcast room, both treated to improve frequency response and achieve a reverberation time of less than 500 ms.
The study shows that this arrangement is feasible within the budget, but highlights that larger studios require different approaches and higher costs.
