The video generation system stores a plurality of target image information and a plurality of map tile image information. Each target image information corresponds to a unique target location identifier, and each map tile image information corresponds to a tile location identifier and a tile image level. The video generation system includes a map display platform, which is provided with a target viewport.

[0057] The target flight is the historical flight for which a flight trajectory needs to be drawn and a trajectory video generated. The departure location identifier for the target flight is the identifier corresponding to the target flight's departure location, and the arrival location identifier is the identifier corresponding to the target flight's arrival location.
