Accordingly, the terminal device detects the clip video segment modification operation through the interactive device, and determines that the filled video empty spaces correspond to modified video segments in the selected video material according to the clip video segment modification operation, for example: the current clip video segment is selected from the first 3.5S video segment in the video material, and the modified video segment may be the last 3.5S video segment in the video material, but the embodiment is not limited thereto, and the user may arbitrarily select a segment of the video segment in the video material. And then the terminal equipment corrects the clip video segment corresponding to the filled video vacancy according to the corrected video segment and the filled video vacancy to obtain a corrected clip video segment, plays the corrected clip video segment and displays the corrected clip video segment through a display device. Wherein the playing effect of the modified clip video segment is the same as the playing effect of the playing segment of the filled video vacancy in the template, and the duration of the modified clip video segment is equal to the video duration of the filled video vacancy. Therefore, the user can correct the clip video segment corresponding to the filled video vacancy from the selected video material in time, and the video processing efficiency is further improved.
Optionally, the duration of the modified video segment is equal to the video duration corresponding to the filled video slot. Or the duration of the modified video segment is greater than the video duration corresponding to the filled video vacancy, and the modified clip video segment includes the video segment with the video duration corresponding to the filled video vacancy in the modified video segment. Or the duration of the modified video segments is less than the video duration corresponding to the filled video slots, and the modified clip video segments include video segments obtained after the modified video segments are repeatedly overlapped.

In this embodiment, after the terminal device displays the clip video segment corresponding to the filled video empty space through the display device, if the user considers that the playing effect of the clip video segment is not satisfactory, the user may reselect the video material, and the user may perform a video material replacement operation on the interactive device of the terminal device. Correspondingly, the terminal equipment detects the video material replacing operation through the interaction device, and determines the replacing video material selected by the user according to the video material replacing operation. Then, the terminal device processes the replacement video material according to the video vacancy to be currently filled, and processes the processed video material according to the playing segment of the video vacancy to be currently filled to obtain a replaced clip video segment, and plays and displays the replaced clip video segment, and a specific implementation process may refer to relevant description in S102 in the embodiment shown in fig. 1, which is not described herein again. The playing effect of the replaced clip video segment is the same as the playing effect of the playing segment of the filled video vacancy in the template, and the duration of the replaced clip video segment is equal to the video duration of the filled video vacancy.
