Vidu Q1
A cinematic children's mystery movie opening. A large green school chalkboard fills the frame, inside a colorful elementary school classroom. The camera is completely steady, facing the board straight on. Suddenly, many colorful individual letters begin appearing on the green chalkboard, as if animated by an invisible force. The letters are bright and playful, in different colors such as red, yellow, blue, orange and white. They move rapidly across the board, spinning, bouncing, crossing paths and becoming mixed and scrambled together in a playful but mysterious way. The colorful letters briefly form a chaotic jumble in the center of the chalkboard. Then, as if controlled by a magnetic force, all the letters smoothly separate from one another and rearrange themselves into a perfectly aligned movie title. The final title must clearly read exactly: "DETETIVES DO CORREDOR B" Keep the letters large, colorful, playful and perfectly legible. The final title remains centered on the green chalkboard for several seconds. Warm cinematic lighting, charming children's adventure atmosphere, subtle mystery, polished high-budget family movie aesthetic, realistic classroom textures, cinematic depth of field, smooth animation, whimsical but not childish, visually exciting opening sequence. No people, no teacher, no additional words, no subtitles, no logos, no watermark. The only text visible at the end must be exactly "DETETIVES DO CORREDOR B".
