I think the engines/props are linked with a shaftFrom Wikipedia: “The V-22’s two Rolls-Royce AE 1107C engines are connected by drive shafts to a common central gearbox so that one engine can power both proprotors if an engine failure occurs. Either engine can power both proprotors through the wing driveshaft. However, the V-22 is generally not capable of hovering on one engine”
a loss of tail rotor effectiveness….perhaps that happens with the loss of one engineGenerally no, but the lower you are, the less time you have to transition to auto-rotation, especially with little forward speed.
Is it me or is it flying out backwards?
An in-air explosion follows and strong rotation.

It is. It was discussed at length on PPRuNe. It is a technique used when there are obstacles you can’t outclimb in forward flight. By flying out backwards rather than straight up the pilot keeps the take-off area in sight so that in case of an engine failure (s)he can immediately autorotate back to a landing.
Reading about this, it appears to be a standard procedure whereby you depart backwards (so upon an engine or other failure you can transition to a forward direction descent and head back for the pad) and then from a specific height you transition to forward flight.
The failure would seem to have taken place around the transition point. Probably not the failure of one of the engines, so the thread title is probably not relevant.

I’m not sure it is an explosion. More likely the landing lights become directed straight at the camera.
And the rotation starts first.
The video shows the helicopter being flown in a responsible way keeping it inside the engine failure return envelope as it goes out of shot, it returns to the video picture rotating rapidly probably indicating the failure of some part of the tail rotor system .
