Delete the drone and the foreground track / vehicle-body edge in the lower-left of the [reference video 1] frame, and naturally fill in the deleted areas.
Keep the giraffe herd, tree branches, distant savanna, golden backlit sunset, aerial perspective, and shot composition completely unchanged. The filled-in background should be consistent with the surrounding environment, generating natural sky, gaps between branches, and grass detail, with no smearing, flickering, deformation, ghosting, or jitter. Ensure the frame-to-frame temporal consistency and continuous motion of the video before and after, with natural edge transitions, the whole looking like the original live-action footage.
