continuity

At 5-29 seconds into the clip it opens up to a image of the gang looking around as the camera switches between the main characters and the other gang using a eye line match shot to create the effect that they're surrounded by this group

At 31-41 seconds in, the camera pans across a street as it follows the gang as they running across the road then jump cutting back to show that they're being chased by this other gang as they run after them seemingly with malicious intent

Then at 48-1:09 seconds it has them stopping as it uses the shot reverse shot t
o show that the gang are being chased down as it then does a close up on the at the main gangs point of view using a eye line match shot to give the other gang an intimidating feeling as if they're inferior and weak.

Then at 1:19 it then also uses shot reverse again to show that the gang is still being chased and that they're still right on their tail giving another sense of intimidation giving the audience a bit of a scare.

Again at 1:48 - 2:55 the film uses shot reverse shot again showing us that the other gang is still running after then and doesn't seem to be slowing down as then has a close up then a zoom out showing us that they have angered expression on their faces intimidating the audience even more

Then at 3:38- 45 it has a match on match action shot of Ajax (the main guy in the shot at the moment) beating up one of the other gang members giving a more action film based feel rather than just having them start to be chased by them then has the rest of the gang joining in as the film uses more match on match action.

then finally at 4:29 we've got some more shot reverse shots to show both sides of the fight that is going on as it seems that Swan (red guy in shot) has been backed up into a corner and is seemingly loosing the fight as he then obviously wins the little brawl.
