Prompt
The character @Image1 is standing on the top of a snowy mountain under clear, sunny weather. The entire sequence is shot with a handheld camera. Start with a tight close-up on the face, then cut rapidly through several quick shots, including putting on a helmet, wearing goggles, and fastening the snowboard bindings. The main character then accelerates downhill at high speed, performing multiple stylish freestyle tricks. The snowboard carves through the snow, kicking up large sprays of powder. Use dynamic follow shots and spinning camera movements, ultra-wide angle with strong depth and perspective. Finish with a dramatic rising crane shot. Cinematic quality, high-energy pacing, synchronized rhythmic music, realistic physics, 4K resolution.

Image-to-Video Comparison (Prompt D)
Second I2V test with the same reference image set and motion intent to compare temporal consistency.
Prompt
Minecraft cinematic biblical scene in a wide desert valley under a bright midday sun. Two large armies stand far behind watching the duel between David and the giant warrior Goliath. Young shepherd David stands confidently holding a traditional shepherd sling made of two leather cords with a small pouch holding a smooth round stone. David begins spinning the sling in a circular motion above his head. The sling rotates rapidly in a full circle as the cords stretch outward. The camera moves dramatically around David as he swings the sling faster and faster. David releases the sling and the smooth round stone launches forward at high speed. The camera follows the stone flying through the air. The stone strikes the giant Goliath directly in the center of the forehead. Goliath freezes for a moment, then slowly loses balance and collapses backward to the ground, creating a large cloud of dust. The armies behind them react in shock. Epic cinematic lighting, dramatic slow motion, dust particles in sunlight, wide angle cinematic shot, Minecraft animation style
