The video obviously is wrong. While nowadays we have the luck of having presents brought by Santa and The Three Wise Men (Reyes Magos) on Christmas Eve and Epiphany Eve, when I was a kid only Los Reyes Magos were bringing them. Not sure if that was a Catholic thing or a wealth one. However we were aware of Santa's existence and we already knew he spent part of his holidays on our sunny and warm beaches, but not in summer, but around the Easter time. Tapas, jamón de bellota pata negra, Ribera de Duero and all those gourmandises are to blame of his round belly. I saw him several times when I lived in the Mediterranean Coast
