Which concept is used to output an animation or video sequence from multiple visuals in a single file?

• A. Typography
• B. Master pages (InDesign)
• C. Layers (Photoshop)
• D. Time-based design

Answer: (D)

Time-based design centers on how visuals change over time, which is essential for animation and video. It uses a timeline to arrange multiple visuals in a sequence, control how long each part lasts, and apply motion or transitions between them. This setup lets you export everything as one file that plays as a video or animation, rather than producing a static image. Typography deals with arranging text, Master pages manage consistent layouts across pages, and layers help organize elements within a single image (sometimes supporting basic frame-by-frame animation), but they don’t inherently enable outputting an animation or video sequence from multiple visuals in a single file like time-based design does.
