The video appears to have been made just prior to the latest round of terminations as at the 14 minute mark it talks of a rumour of 600 pilots being called in. However it illustrates the criteria used to select crews, how the crews were dealt with and the issues facing those remaining in Dubai. Some reports say 700 cabin crew but I think this is a typo as an A380 would have about 20 cabin crew and a B777 would have about 15 so ratio wise 7000 cabin crew to 600 pilots seems about right.
