crowd of people gathered near a racetrack, with cars speeding past on the track. The sky is cloudy, and there are tents and buildings visible in the background. The people in the foreground are standing around talking, and they appear to be enjoying the event. Several flags are visible at the event, including one for Belgium and a green and white flag with the words "100 years". The video seems to have been taken by someone within the crowd.
