1. Problems Solved by BMP Compositions
BMP composition is a minimum guaranteed solution that can handle all AE features, but it is best suited for scenarios where certain AE features cannot be exported. These include particle effects, third-party plugin effects, and complex and time-consuming AE effects. In terms of performance, pure vector graphics typically perform better than pag files with BMP composition.
For the AE features currently supported by PAG, please refer to the article: AE Feature Support List

After completing the check as shown in Figure 8, the corresponding composition name can be seen in AE automatically with the BMP suffix. When exporting, it will be encoded as a video sequence frame or a bitmap sequence frame.
