Lightning strike in the clouds above while filming distant sheet lightning

During nineties I used to try to film thunderstorms and lightnings on video. One night when I was filming distant sheet lightning this happened. You can see the lightning strike on the ground about four kilometers away, then spreading wildly on the clouds. The final "hit" was somewhere far behind me in the clouds and and I tried to follow it (the camera shifts upwards in the end)
