The video shows a woman standing on a stage in front of a large screen. She is wearing a black jacket and holding a microphone. The screen behind her displays the words "TEDx Bergamo" and "Martina Caioni La variabile 'X'". The woman is speaking to the audience, and her body language suggests that she is passionate about her topic. The stage is well-lit, and the audience is not visible in the video. The woman appears to be the main focus of the video, and her presentation seems to be the central event.
