Video prompt: A gentle river winds its way through a bustling forest, sunlight dappling the water as it trickles over smooth stones, deer pausing to drink from its cool, refreshing stream.
Defect: Deformation (any reason involved with a movement)
Explanation: The body of the deer changes shape in an unnatural way during movement, which is unrealistic, as the deer's form should remain stable. The boundaries between the two deer become blurred and indistinct.
