One of the cinematics was indeed Crossroads. Turns out Blizzard modified the encryption tech in 8.2 to not distribute the keys anymore as soon as you deliver the quest so all the automated cache submissions MMO-C/WoWHead have won't actually have the key saved in them unless the person logged off when they took the quest that has the cinematic during it. Oof!
One encrypted cinematic left. Hopefully that one is actually new.
