In the application, the multimedia platform can determine a first transition mode set corresponding to the format types of the plurality of material combinations, and determine a transition mode in the first transition mode set as a target transition mode.
For example, after determining that the format type of the combination of the three materials is the video type, determining the superposition and the rotation field 1 in the transition mode set corresponding to the video type as the target transition mode, where the superposition is used for performing the transition processing on the first material and the second material, and the rotation field 1 is used for performing the transition processing on the second material and the third material.

As another example, when the number N of videos to be generated is 1 Greater than or equal to N 2 At this time, some of the transition ways in the second set of transition ways are determined to be N 2 Target transition mode corresponding to each video, wherein N is as follows 1 ≥N 2 > 0. When the number N of videos to be generated is 1 Less than N 2 At this time, some of the transition ways in the second set of transition ways are determined to be N 1 Target transition mode corresponding to each video, wherein 0 is less than N 1 ＜N 2 。
