The video shows a large herd of wildebeests crossing a river. The wildebeests are seen swimming in the water, with some struggling to stay afloat. The river is flowing rapidly, and the wildebeests are moving in a group, with some leading the way and others following behind. The wildebeests are mostly dark brown in color, with curved horns and long, thin legs. The water is murky and brown, and the surrounding landscape is rocky and barren.
