In the video, a person is seen holding a fish with one hand and using a knife in the other hand to cut the fish. The fish is lying on a black surface, and the person is cutting it from the tail to the head. The person's movements are steady and precise, indicating that they are experienced in handling fish. The fish appears to be a large one, with a shiny, silvery body and a long, pointed tail. The knife used for cutting is sharp and appears to be a filleting knife, which is commonly used for preparing fish. The background of the video is not clearly visible, but it seems to be an outdoor setting, possibly near a body of water.
