That ‘mysterious creature’ in your backyard is probably just AI having fun

So you're scrolling through X and stumble upon this grainy nighttime security footage: a bizarre, two-legged creature with massive ears, standing about three feet tall, having a fight with a very confused and, frankly speaking, scared cat. The caption claims it's proof of... something. But before you start believing in backyard monsters, let's ask the real question: is this video AI-generated or did someone actually capture Dobby from Harry Potter?

We fed this mysterious footage to our AI video detector and got an 80% AI-generated result. The analysis revealed some classic giveaways such as inconsistent textures and movements beyond the laws of physics. It's amazing what AI video generators can create these days, but they still struggle with natural physics and authentic animal reactions.
