Ultra realistic video recorded with a modern smartphone: a 2-meter giant sea turtle slowly crawling across a sunny beach. The camera is handheld at close distance, slight natural shake as if filmed by a person. Bright daylight with a clear blue sky, gentle waves breaking on the shore, seagulls flying above. Highly detailed textures of the turtle’s massive shell, wet sand, and water reflections. Raw, realistic footage style, no cinematic filters, no text or logos.
