Looks about right when comparing it to this. The high frontal perspective of where the video footage was taken would also make it seem as though the nose was pitched higher than it actually is in the flare.At 1:47, the landing angle seems a bit too steep and i think the J-10's rear touched the runway a bit.
Never flown fighters, but for reference - the A320 has a 12-13 degrees nose up pitch during the landing flare, leaving about 2 feet (basically from the ground to the average human knee) of clearance before the tail strikes. On the other hand the Dash-8 I used to fly could only pitch up to 5 degrees nose up on touchdown (6 degrees to get a greaser, but you have to be SO careful) before the tail strikes the runway at 7 degrees nose up pitch.
Basically what I'm trying to say is that there isn't a standard nose up pitch attitude that all aircraft land, what looks normal on one plane might not look normal on another. Fighters land using AoA anyway, quite frankly I'd often come across pilots that were ex-military that've been used to years of slamming it onto the tarmac (especially those coming from a naval background) as long as they arrest the rate of descent enough to not break the undercarriage.
