Narrative B-roll should support the sentence being spoken without competing with it. Use slow camera movement, one subject, and a stable composition with negative space for titles. A history channel might animate a map-like illustration; a technology channel might create a cinematic server-room transition; a travel essay could extend a destination photo with drifting weather and a measured camera glide. Build a small library of five-second clips and place them only where the narration needs visual relief.

A Short must explain itself on a phone immediately. Lead with the motion—zoom, reveal, drop, transformation—then specify the subject. Keep the background simple and center important details inside the safe area so interface buttons do not cover them. One AI clip can become the opening hook; two or three matched clips can form a compact visual sequence under a fifteen-second voiceover.

Modern intros should promise the payoff rather than delay the video. Animate the thumbnail concept for two or three seconds: the central object moves, the environment changes, or the camera reveals the question the video will answer. Cut directly into narration while attention is high. Keep logos and text for your editor, where spelling and timing remain under your control.

Write 16:9 prompts like a patient camera direction: establish location, subject, atmosphere, and one deliberate move. Write 9:16 prompts like a feed hook: immediate action, close framing, fast contrast, and a readable ending. Reframe intentionally rather than cropping a finished wide clip, because the model can compose motion for the final canvas from the start.
