No, take off real (exaggerated by camera position and angle).
One of the most memorable sights in my life was watching my father depart Rockhampton in a B777 - he had delivered a load of Singapore Armed Forces grunts, so going back to Singapore he was essentially empty - captain, F/O, second officer and fuel...
So, he didn't need much coercion to demonstrate an essentially empty B777 at max angle of climb... I mean 800kN+ thrust total... almost empty airframe.... (same situation as in the Dreamliner video)...
Yeah, it was STEEP and severely impressive! NEVER forget it.
Another VERY memorable experience was 1990 out of Frankfurt in a Birdseed (BA) B757 - Capt was asked max performance to get out of there for sequencing as we were running late. He got out of there alright..firewalled, pointing up and went like a bat out of hell (B757 is over-powered for the airframe, which is a good thing

)
