Hook, split-screen, overlay, B-roll: these terms describe in a few words a visual language now omnipresent, fast, codified, and yet still poorly mastered. This course offers an exploration and hands-on practice in creating videos specifically designed for social media platforms, their narrative codes and technical constraints. Using their smartphones and provided action cameras, students will conceive and produce both videos tailored to the main platforms (Reels, TikTok, Shorts, LinkedIn) and more experimental forms. The course will cover the entire production chain, from concept writing to filming, editing, and dissemination. Special attention will be given to effects, transitions, subtitles, and techniques suitable for graphic and animated experiments. Throughout the semester, each student will develop a personal video creation project rooted in their practice and research. The goal is to provide tools for transforming a complex subject into concise and impactful capsules, without losing its substance and while developing a unique digital writing style.
