Probably a couple a factors going on here...but impossible to tell just from
a video.

1. Weight
2. CG problem..probably aft...which would make rudder potentially worthless
3. High altitude and hot.....
4. Grass strip....lengthening takeoff roll.

My guess is the plane was probably over weight with a rearward CG. This
would explain the nose up attitude and yawing of the aircraft. In addition,
I don't think he lost dirrectional control...he never had it.

Perhaps he is always used to rotating at 60 kts. Throw in the above factors
and not only will the plane not fly....but it will be difficult to control.
His needed rotating speed adjust for weight, altitude, temp, winds, may have
been much higher....grass strip wouldn't help matters either.

JMHO

One last thing....as soon as the plane lifts off the ground the right wing
dips...this would tell me that for whatever reason he had insufficient
airspeed to make the wing generate lift.

Check this clip out. What does everyone think happened here?

It looks like a 182, so it had *some* muscle.

I think it must have been hot, maybe a high elevation, loaded with fuel,
people and equipment. But one passenger was a small boy so he couldn't
have been very heavy.

It also looks like a soft-field technique that was poorly executed and he
lost directional control and didn't lower the nose to build airspeed
first.

Very sad,
