What kind of shooting techniques did the secret kingdom of documentary adopt?

Manual shooting, this kind of shooting can only be done manually on the platform, such as artificially building a natural environment, then putting animals in it, and then shooting alone. On the colorful and noisy streets of Rio de Janeiro, a little marmoset found himself separated from his companions, and he had to face this busy and chaotic city alone, not to mention the hidden dangers here. In the futuristic metropolis of Tokyo, a unicorn escaped capture. In order to find shelter, it began an extraordinary journey through this strange world and told the story that two small animals had to grow up quickly. On the African prairie, a young elephant shrew realized that speed is the key to survival among the largest animals in the world. In America, a young locust-eating mouse met the deadliest animal in the west, and it tried its best to keep its territory.

In the ancient wild forest of North America, a little chipmunk was collecting and storing nuts for the first winter of its life, but it met countless ruthless opponents and hungry large carnivores along the way. In the humid tropical rain forest, a young tree shrew had to go deep into the jungle to find food. It must concentrate and move quickly, because it wants to escape from the ultimate predator in the jungle-as always in movies, take a clip, take another clip, and then synthesize. Otherwise, you can't shoot, such as high-speed cameras. These are very big, and many operations require several people to concentrate. If there are many people, how can animals hunt? Shoot a snake alone, shoot a mouse alone, and then synthesize. There is such an unknown world that human eyes cannot see.
