After researching, I came to the conclusion: the use of motion capture in a film can enhance the interaction between the audience, the characters and the fictional world, but there are still certain limitations. For example, there are great limitations in the application field of motion capture. If motion capture is used in animated cartoon films, it will only backfire. It will not only lose the essence and characteristics of animation performance, but also bring the audience a strange visual experience. However, in special effects films with ordinary performances, the use of motion capture can greatly reduce the workload, make the characters more realistic and vivid, and improve the quality of the entire film, although the technical cost needs to be considered.
