P1 is the fixed template video. P2 is the single image uploaded by the user and provides the exact identity and appearance of the main product, object, pet, or non-human subject. Recreate P1 shot by shot and frame by frame. Replace only P1's featured subject with the recognizable subject from P2, preserving its shape, color, material, markings, proportions, and distinctive details. Keep P1's position, scale, motion, interaction, camera movement, composition, background, environment, supporting objects, lighting, effects, transitions, timing, audio, music, sound effects, synchronization, and aspect ratio. Apply P1's costume, fantasy treatment, or transformation only when it is part of the template, without losing P2's recognizable identity. Never use P2's background. Do not invent a different product or animal, convert it into an unrelated human, add duplicate subjects, extra limbs, hands, text, subtitles, logos, or unrelated props.
