1# If you render a black-and-white sequence, you can add a special effect of "lens blur" to this sequence in AE, and then adjust the mask layer to your black-and-white sequence layer, and adjust the parameters to achieve the desired effect. In addition, you can actually output rpf or ral format. When outputting, you can select the Z channel option to include the Z channel in the picture. Then you can add a depth of field effect to the channel effect group in AE, and you only need to adjust the distance of depth of field. No matter which method is used, the depth of field effect can be achieved, but the speed is slightly different.
