Steven Spielberg encouraged director Michael Bay to limit the dependence of robots and background elements on computer graphics in the action scenes. The stunts of the Bone Smasher crashing into a bus are live shooting. The camera is placed on the collision and explosion of the vehicle. In the scene, to make the scene look more exciting. Production of the traditional animation used in the film began in April 2005. Michael Bay stated that three-quarters of the special effects in the film were produced by Industrial Light and Magic, and the rest were done by digital companies, including in the Arctic. Discovered Megatron, the bewildered beheaded head and the scene of a vending machine activating mutation by fire. Many animators are loyal fans of Transformers, and they have freely played in many ways: the scene where the jazz jumped onto the saboteurs in the film is based on similar scenes in the 1986 version of the movie "Transformers."
Industrial Light and Magic spent six months in 2005 to produce computer animations of robot deformation, carefully comparing every detail on the car model. At first, these deformation processes followed the laws of physics, but they changed more smoothly because they didn't seem to be stimulating enough. Michael Bay rejected the proposal of using liquid metal for the character's face, and chose the "Magic Cube" style. He hopes that there will be more mechanical parts on the robot, so that it can look more interesting, real, dynamic and fast, rather than like a clumsy beast. An important decision in the stunt production process is to keep the wheels in contact with the ground for as long as possible so that the robot can keep moving while deforming. Bei also asked the animators to observe two videos of martial arts performances and multiple martial arts films, in order to make the fighting scenes in the film look more beautiful.
Due to the complexity of Transformers design, even a simple action like turning the wrist requires 17 visual elements. Each gun of the iron sheet is composed of about 10,000 parts. The Hornet uses a panel to act as the eyebrows. It is also necessary to rotate multiple parts of the face to show the effect of a smile. The eyes of all characters have been designed with pupil dilation and brightening. Michael Bay said that these visual effects are so complicated that Industrial Light and Magic spent 38 hours just to render one of the moving pictures, which also means that the company must increase processing equipment. Every rendered part must look like real metal, whether it is shiny or not. This makes model making very difficult, because those clean vehicles have to transform into old and scarred robots. The close-up shots of the robot have been accelerated to make it look more "cool", but in the wide-angle shots, the animation speed needs to be slowed down to create a convincing sense of weight. Photos were taken in each group of shots and used as a reference for the computer to reproduce the lighting environment, in order to make the robot look like it is really moving in such an environment. Bei has directed many car commercials before, and he knows that ray tracing is the key to making these robots look more realistic. The real degree of computer-generated models depends on the degree to which the surrounding environment reflects on these models. The robots are programmed with a variety of simulations so that the animators can concentrate on the animation of the specific areas needed to make the shots look more realistic and believable.
In order to enhance the sense of reality, Michael Bay abandoned the square and blocky shape of the robot and replaced it with a robot shape with a large number of detailed parts. In a deformation process, thousands of components of the robot will move at the same time, thus avoiding the phenomenon that the volume and mass of Transformers can be arbitrarily reduced and enlarged in Transformers cartoons, which is difficult to explain with daily physics. The unique shape of Transformers also highlights the fundamental trait that they come from an alien.
