I am a paragliding pilot and I upload all my flights to XContest. I also film videos of some flights and I upload them to YouTube. XCvid combines the video player from YouTube with a tracklog from XContest. Cesium is used both for 3D view and for 2D map, there’s also a height profile.
My camera battery usually doesn’t last the whole flight so I start and stop the camera several times during the flight. An essential feature of XCvid is that it can combine these individual videos to one playlist and show them in the context of the flight.
You can view more pilots in Cesium. It’s also possible to show just the flight with no video.
