Too small to see , and I can't enlarge it , just the the imageshack main page.
By the looks of it its X-peral if your talking about the char portraits.
Can you link the movie??? Just one image of a Combat text inst really alot.

could it be an extra function in an combat text addon?
Looks like Mik's scrolling Battletext.
woops sry didn't see the circle looks ike miks scrolling battle text or scrolling combat text
Looks like MSBT (Mik's Scrolling Battle-Text) with a non-standard configuration.
Hint: You can configure MSBT's scroll-areas as you like. Move them, change speed and direction, font, scrolling-style etc.
Most likely to be ScrollingCombatText, with the option: Show above character enabled.
