I made this video from clips taken throughout 2011 of friends and I shooting various guns, at various things. In the video there are several slow motion scenes (at 50% speed) and several first-person helmet cam clips.
The following guns are in the video:
Cobray M-11/9: full-auto submachine gun
Mossberg 500: 12-gauge shotgun
Armalite M15A2: 24" barrel .223/5.56 single fire assault rifle
Colt AR-15 M16: select fire (single, three round burst, full-auto) .223/5.56 assault rifle
The video clips were filmed using a couple Canon Rebel T2i (550d) DSLR's using the 18-55mm kit lens and a 50mm f/1.8 lens, and a GoPro Hero HD for the first person shots. Clips were filmed at 1080p @ 30 fps or at 720p @ 60 fps for slow motion.
