it's literally two seconds but i am already loving this depiction of the orks.
like with everything astartes-guy has done, he's doing an amazing job getting that sense of transhuman dread across. orks aren't just nutso football hooligans, they're seven foot tall bags of muscle that club space marines to death through their armor with sheer hammering force. and the speed, the sheer violence of action, man. we get ten or so frames of the ork scene before the first ork gets squished, no time at all, and the head squish is only four frames. first frame: fist comes into view, 2nd: fist is already in the guy's face, by the 3rd the head is gone entirely.
as soon as the head is gone we can see the second ork coming into view where it just was, relatively long sequence here (about ten-ish?) with most of the motion in the head as the marine turns to look and the ork crosses the screen. the right arm starts moving at the same time the choppa comes on screen, and impact is about five frames in. then we hold the impact for about three frames while sparks fly, marine pushes the axe away with his right hand in a couple of frames.
then, even if it doesn't feel like it, the second punch takes a long time (for astartes at least). the left hand is already on screen as the axe is being pushed away, and the motion (from fingers forming the fist to impact) is a whole 12 frames. it's barely a half second of anticipation, blink and you'll miss it, but you can see the punch being telegraphed and the ork's face getting pulled closer and damn it, somehow it works. we hold the aftermath of the punch for about 6 frames as the ork falls off screen, then the marine gets about six more frames on his own before being dogpiled.
the whole thing is, what, three seconds? god damn.
edit: like, there's this little hold here before the second punch when the arm is sort of sitting still, bottom-center across the screen and the fist is being formed, maybe an eighth of a second, that you should not be able to notice. it's so fast. but somehow you catch it while seeing the ork come closer and it perfectly primes you for that pivot punch. the way that second punch is shot feels amazing too, like you're following the fist in.
this is overly long and gushy for zero actual insight but god, the animation in the originals was good and this is impressive even on top of that.
