The aircraft 62 sequentially executes the flight actions corresponding to each flight mode according to at least one flight mode included in the flight control instruction, and the camera 623 captures video clips in each flight mode and transmits the video clips to the control terminal 61. The control terminal 61 may perform clipping processing on the video segment according to the obtained clipping parameter of the target theme, so as to generate a video. It should be noted that the click operation on the user interface of the control terminal is only one method for confirming the target theme, and the embodiment of the present invention is not limited to the confirmation manner of the target theme.

In one embodiment, the control terminal may determine a theme selected by the user from the at least one theme as a target theme by acquiring a selection operation of the user on the at least one theme provided in the combined flight mode.

In an embodiment, when determining the flight mode of the target theme, if the editing instruction is acquired, the control terminal may edit one or more flight modes provided in the target theme, and determine the one or more flight modes after the editing processing as the flight mode of the target theme.

In one embodiment, the editing process performed by the control terminal on the flight pattern in the target theme may be an adding process performed on the flight pattern in the target theme. Specifically, if the control terminal detects an adding operation after determining the target theme, the control terminal may obtain an adding instruction and display an airplane mode option to be selected for a user to select. If the control terminal receives the selection operation of the user on the flight mode option to be selected, the control terminal can acquire the flight mode selected by the user.

Assuming that the control terminal acquires the click operation of the determination button 817 from the user after detecting the selection operation of the user on the two options of the spiral flight mode option 815 and the comet surround flight mode 816, the control terminal may add the selected spiral flight mode option 815 and the comet surround flight mode 816 to the flight mode of the target topic as shown in fig. 7.
