Before and after
Good image-to-video prompts replace vague taste words with visible motion structure.
The better prompt does not have to be longer for its own sake. It has to make the starting frame, subject motion, camera behavior, continuity anchors, and failure constraints easier to inspect.
Example 1: Product still
Source frame: A compact silver skincare can sits upright on a dark subway seat beside a rain-speckled window, lit by passing city reflections.
Weak prompt: Make this product cinematic, premium, glossy, with cool city vibes and nice camera movement.
Revised prompt:
Start from a reference frame showing a compact silver skincare can sitting upright on a dark subway seat beside a rain-speckled window. The can tilts slightly toward the camera, catches a moving streak of reflected light, and settles back into center frame. Use a slow push in with controlled handheld drift. Keep the can label readable, preserve the exact silver finish, and keep the subway seat and rain-speckled window stable. Avoid warped packaging, changing label text, extra objects entering frame, or abrupt zoom jolts.
Why it works: The revised prompt names the source frame, one product motion, one camera move, and the details that must not drift.
Example 2: Character reference
Source frame: A young woman in a blue bomber jacket stands on a rooftop at blue hour, hair tied back, city lights softly glowing behind her.
Weak prompt: Animate her naturally with emotion and make the shot feel like a beautiful movie scene.
Revised prompt:
Start from a reference frame showing a young woman in a blue bomber jacket on a rooftop at blue hour. She turns toward camera, the jacket catches a light gust, and her expression resolves into a subtle half-smile. Arc the camera gently from three-quarter profile into a medium close-up. Keep her face shape, hairstyle, jacket color, and rooftop background stable from start to finish. Avoid identity drift, changing clothing details, extra fingers, or exaggerated facial morphing.
Why it works: The revised prompt gives the model a single expression beat while preserving the identity and wardrobe anchors from the still frame.
Example 3: First-frame continuation
Source frame: A dancer frozen mid-spin in a neon-lit warehouse, one arm extended, reflective puddles glowing on the floor beneath scattered haze.
Weak prompt: Continue the dance with lots of energy, dramatic neon lighting, and cool camera tracking.
Revised prompt:
Start from a reference frame showing a dancer frozen mid-spin in a neon-lit warehouse with reflective puddles and scattered haze. The dancer completes the spin, lands into a low step, and resolves cleanly toward frame left. Track just enough to keep the dancer centered while haze moves in slow ribbons and puddle reflections ripple underneath. Keep the outfit, warehouse layout, and reflective floor stable. Avoid duplicate limbs, chaotic background changes, broken anatomy, or over-smearing the motion.
Why it works: The revised prompt turns vague energy into a readable start, movement, and resolved end beat.
