Is this takeoff of a 767 in bad weather conditions a normal procedure? In this video, a 767 takes off in bad weather conditions. The comments of the video aren't very professional, so I ask here:


Is this a legitimate takeoff?
Some comments say that this was a close takeoff. Some comments do point out that on rotate, you can see the end of the strip of the lefter runway. Was it airborne before?
Take-off within the crosswind limits is a normal procedure. From the video it's hard to tell what the crosswind was in this particular situation, so it is impossible to tell about the legitimacy of this take-off. 

Rotation seems to be on the 1000ft marker, i.e. 1000 ft from the runway threshold. But in case of a displaced threshold the take-off distance available may be more than 1000ft from that point. It was airborne before the end of the runway.
