In recent years, 3D animation technology has developed at a rapid pace and has been used in a variety of fields. In the field of architecture, the use of bespoke 3D animation techniques to simulate the exterior and interior details of a building can not only help designers to communicate their design ideas, but can also be used in marketing to give purchasers a more visual understanding of the building. However, the production process of 3D animation is limited by storage capacity and bandwidth. In order to reduce the load of 3D data on the bandwidth, it is necessary to choose an appropriate compression method to compress the 3D data. This study introduces the Motion Picture Experts Group format algorithm to optimise the traditional algorithm for compressing 3D animation in the hope of achieving better compression results. The experimental results showed that for the quantization table filling method, linear function compression worked best. For the choice of sub-block size, the compression effect of sub-block size of A is the best and the reconstruction error is lower. The compression effect is significantly improved by introducing a local linear embedding algorithm for dimensionality reduction, and the combination of a digital zero processing algorithm and a discrete cosine transform results in better compression. In comparative experiments of 3D animation compression based on the Motion picture expert group format algorithm, the Motion Picture Experts Group format algorithm outperforms other algorithms. The experiments confirm the superior compression performance of the Motion picture expert group format algorithm and show that the Motion picture expert group formatalgorithm has some application value in architectural animation adaptation.
