Video prompt: A serene forest clearing where deer cautiously graze, their ears twitching with every rustle, as sunlight filters softly through the canopy above.
Defect: Deformation (any reason involved with a movement)
Explanation: The deer in the background transforms into a highly blurred spot as it moves.
The extreme blurring of the background deer is unrealistic, as it should remain distinguishable and maintain a consistent shape rather than turning into an indistinct spot.
