The video description reads:

"Alaina was set to get married in March of 2013 but her dad, Dennis, was slipping away from us due to cancer. We feared he wouldn't be here in person to hold his daughter in his arms for their final dance that day. So in early November 2012 we stepped into a ballroom and I was able to capture an incredibly special moment between a dad and his little girl. Dennis Heston entered God's presence on December 9th, 2012, just one month to the day after we filmed this dance. Thank you God for letting us keep your boy Dennis here with us on earth for a little bit longer. We miss you bunches Uncle Dennis!"
