The descriptions of steps S201 to S202 may refer to the descriptions of steps S101 to S102, and are not repeated here.
S203, the terminal 100 detects a network state with the server, and/or detects whether the size of the first video is greater than a preset threshold.
The terminal 100 may detect whether the network state with the server 200 is lower than a set threshold condition, for example, whether the current network bandwidth between the terminal 100 and the server 200 is greater than a set threshold, and for example, whether the network connection type between the terminal 100 and the server 200 is a 5G network connection. If the 5G network connection is made, it indicates that the network state with the server 200 is higher than the set threshold condition, and if the network connection is not made, it indicates that the network state with the server 200 is lower than the set threshold condition.
The terminal 100 may also detect whether the size of the first video is greater than a preset threshold. For example, it is detected whether the size of the first video is less than 100MB. In other embodiments of the present application, the terminal 100 may also detect whether the size of the second video is less than a set threshold, for example, less than 200MB.
In some embodiments of the present application, in step S204, the terminal 100 may perform the step corresponding to the case 1, that is, perform steps S204-S208, when detecting that any one or any two of the above conditions are satisfied, where the terminal 100 sends the first video to the server 200. That is, the terminal 100 may perform case 1 when:
1. the size of the first video is larger than a preset threshold value;
2. the network state with the server 200 is less than the set threshold condition;
3. the size of the first video is larger than a preset threshold value, or the network state between the first video and the server 200 is smaller than a set threshold value condition;
4. the size of the first video is greater than a preset threshold, and the network state with the server 200 is less than a set threshold condition.
Case 1: S204-S208.
S204, when the network status is lower than the set threshold condition and/or the size of the first video is greater than the preset threshold, the terminal 100 sends the first video to the server 200.
S205, the server 200 analyzes and obtains an editing scheme for the first video.
S206, the server 200 transmits the editing scheme to the terminal 100.
S207, the server 200 edits the second video by using the editing scheme to obtain an edited third video.
The description of steps S205 to S207 may refer to S104 to S106.
S208, the terminal 100 sends the third video to the server 200 for the server 200 to store.
The server 200 may store the third video clipped by the terminal 100. Other terminals can obtain the third video from the server 200 through the network by logging in the same account.
Case 2:
s209, when the network status is higher than the set threshold condition, or the size of the first video is smaller than the preset threshold, the terminal 100 sends the second video to the server 200.
S210, the server 200 analyzes the second video to obtain an editing scheme, and edits the second video according to the editing scheme to obtain a fourth video.
S211, the server 200 transmits the fourth video to the terminal 100.
The step S209 is not limited to one of the two conditions, and may be that the terminal 100 transmits the second video to the server 200 when the network state is higher than a set threshold condition and the size of the first video is smaller than a preset threshold. In other embodiments, the terminal 100 transmits the second video to the server 200 when the network status is above a set threshold condition and/or the size of the second video is less than a predetermined threshold.
In this embodiment of the present application, when the size of the collected high-quality video (second video) is smaller, that is, smaller than a predetermined threshold, and/or when the network speed is faster, the terminal 100 may directly send the high-quality video to the server for processing, and when the size of the collected high-quality video (second video) is larger, that is, larger than the predetermined threshold, and/or when the network speed is slower, send the first video with the smaller size to the server for processing, and obtain an editing scheme, and edit the second video according to the editing scheme. Therefore, no matter how fast and slow the network is and the video is, the terminal can edit the video by the processing capacity of the server, can rapidly complete the video processing, can improve the efficiency of the video processing, and provides better shooting experience for the user, thereby improving the convenience of the user in using the terminal.
In S210, the second video analysis by the server 200 may obtain the editing scheme as a portion that may be more interesting to people through image recognition, and specific reference may be made to the description of step S104. The specific contents of the editing scheme can also be performed with reference to step S104. The server 200 may edit the second video according to the editing scheme with reference to the descriptions of steps S104 and S106, which will not be described herein.
