Because there are differences in fill sizes corresponding to the locations of the original images in the different composite templates, the original image selected by the user may not meet the requirements of the composite template. For example, if the filling size of the synthesized template is 400px × 600px, the original image selected by the user is scaled and cropped according to the filling size of the selected synthesized template, so as to reduce the memory usage and the overhead of the synthesis performance in the video production process.
It should be noted that, in the process of decoding the composite template, the original image is cropped according to the filling size of the composite template, so that the time for video production is shortened.
In an embodiment, the synthesizing the initial video into the target video in the background further comprises: s330, receiving the description information input by the user on the video publishing page.
In this embodiment, the client receives the synthesis processing operation, and transfers the initial video to the background for processing according to the target video synthesized by the target transformation parameter, and at the same time, jumps from the video editing page to the video publishing page on the current page, and receives the description information input by the user on the video publishing page.
