Conversation
Left-drag in the 3D view turns the flyover camera (yaw/pitch offset from the trajectory heading) instead of orbiting the hidden orbit camera. The offset is applied before Level horizon, so the horizon stays level. Reset look button in the flyover bar; the offset also resets when the flyover is opened.

Record button in the flyover bar writes flyover_<time>.mp4 next to the executable with cv::VideoWriter (H.264, falling back to MPEG-4 Part 2, then Motion JPEG AVI). Captures the 3D view only, before the compass and ImGui, at the window's render resolution. While recording, the playhead advances a fixed 1/30 s per rendered frame, so the video is smooth regardless of render speed. Recording stops at the end of the trajectory, on Stop REC or on Close.
