PetCostumeAI's fat pet running video turns one photo of your cat or dog into a 5-second clip: a comically round version of your pet runs through the living room toward a fixed, pet-height camera, belly bouncing, then stops out of breath and looks up. The video has footsteps and huffing sounds and no music, comes in vertical or square, and costs 300–800 credits by quality.
Image effects create still pictures. Effect videos come with AI-generated sound effects that match the scene, without background music.
