and generating a corresponding special effect request according to the special effect adding instruction and the related information of the terminal equipment.
The information about the terminal device may be the capabilities of the terminal. The special effect request is related to the relevant information of the terminal device. When the special effect adding instruction is the same, if the related information of the terminal device is different, the generated special effect request may be different. If the equipment performance of the terminal equipment is good, the special effect corresponding to the special effect request is a first type of special effect, and if the equipment performance of the terminal equipment is poor, the special effect corresponding to the special effect request is a second type of special effect. The first kind of special effects are normal special effects, and the second kind of special effects are simple special effects. The playing simple special effect has lower requirement on the equipment performance of the terminal equipment than the normal special effect.
Optionally, generating a corresponding special effect request according to the special effect adding instruction and the related information of the terminal device includes:
if the model of the terminal equipment is in a preset white list, generating a special effect request for indicating a third server to return a first type of special effect matched with the special effect adding instruction;
and if the model of the terminal equipment is located outside the preset white list, generating a special effect request for indicating the third server to return a second type of special effect matched with the special effect adding instruction.
The terminal device may preset a white list, where the white list includes models of various terminal devices. After the model of the terminal device is determined, the performance of the terminal device is also determined. The model in the white list is the model of the terminal equipment which accords with the preset performance. If the model of the terminal equipment is located in a preset white list, indicating that the performance of the terminal equipment meets the requirement, generating a special effect request for indicating the third server to return the first special effect matched with the special effect adding instruction, and if the model of the terminal equipment is located outside the preset white list, generating a special effect request for indicating the third server to return the second special effect matched with the special effect adding instruction. The first kind of special effects are normal special effects, and the second kind of special effects are simple special effects. According to the scheme of the embodiment of the disclosure, through a white list mechanism, the type of the special effect request returned by the third server can be better determined, so that the terminal equipment can play the special effect suitable for the performance of the terminal equipment.
Optionally, the sending the editing record to the first server, so that the first server edits the original video corresponding to the material address to be edited according to the editing record to generate the target video, including:
and sending the editing record to the first server, so that the first server edits the original video corresponding to the video storage address to be edited and the first special effects corresponding to the special effect address to be edited according to the editing record to generate the target video.
In the embodiment of the disclosure, the editing instruction corresponding to the editing record includes an effect adding instruction, and when the first server receives the editing record, the first server edits the original video corresponding to the video storage address to be edited and the first special effect corresponding to the special effect address to be edited according to the editing record to generate the target video.
