Ryanair uses all the runway.

Quote "With Normal takeoff thrust, the airplane should easily reach a height of 150 feet over the end of the runway,"

This clearly indicates that the takeoff in the video was not normal.

Is your opinion that the video shows a normal takeoff?

Happy to "help"?

From a B777 FCTM:

It is important to note that the majority of past RTO accidents were not the result of an RTO initiated because of an engine failure. Full takeoff thrust from all engines was available. With normal takeoff thrust, the airplane should easily reach a height of 150 feet over the end of the runway, and the pilot has the full length of the runway to stop the airplane if an air turnback is required.
Making the Go/Stop decision starts long before V1. Early detection, good crew coordination and quick reaction are the keys to a successful takeoff or stop.
