Video from the open kick-off meeting held on 11 March 2019 in Madrid, Span

Here is the full video.

Please note it is our first experience to record a meeting video. Something was (hopefully) good, something (for example, a poor video focus at the very beginning) was not. We believe we will do it better next time.
