This mode is intended for viewing the video file which has been written down during flight of drone, with synchronous displaying a position of drone on the map during viewing. For this purpose it is necessary that at drawing a trajectory of drone's movement with use of the mode «Import coordinates in format KML/CSV» there were specified the semantics for placing of a file name with coordinates and a video file name, and also the name of a video file was indicated. In order that this mode was enabled, on a map the object representing a trajectory of drone's movement should be marked. If several of such objects will be selected only the first of them will be processed. After you start the mode, you must select the names of the semantics that contains the file name with the coordinates and the name of the video file. If the chosen semantics contains the name and the video file exists, the button will become available. After clicking on it the video will start playing. If in semantics containing the file name with coordinates, the name of an existing file is contained, then during playback of video on the map, along the trajectory of drone's movement, the cross showing the position of the UAV on the ground at the moment of playback will move. The button is intended to pause the playback, the button stops the playback, and the further viewing of video will start again. The button accelerates the viewing in 2 times, the button slows down in 2 times. For viewing with normal speed it is necessary to press the button once again. For playback of video files it is necessary that in your system the video codecs have been established. For example, a package of codecs K-lite Codec Pack.
