ok so ur velo/time remap is pretty inconsistent for the style ur going for
if ur on vegas ur gonna wanna do something like:
300% --(3 frames)-> 25% --(center of clip)--> 10% --(3 frames from end)-> 25% --(last frame)-> 300%
since ur trying to emulate the style of syncing/weatherspoon u should have a handful of frames that are actually at 100% velocity at most
your swoosh sfx are really treble heavy when it should be bass heavy
u also have swoosh sfx despite having no pan/crop continuity into the next clip (for example, you would wanna end a clip with a p/c from left to right and start the next clip with that same continuity)
60fps for these kinds of edits arent really that good
ur motion blur (RSMB?) decent so no worries there
u have sfx on only the guns shooting and the explosions when they land (0:28 u can see a soldier gib from a rocket but theres no sound for it)
the initial tile chromatic aberration effect at the beginning is not animated well and its extremely noticeable because the swoosh is out of sync
but most importantly is ur skipping SO MANY BEATS that when u actually do sync to the song its jarring
in weatherspoon's/syncing's latest edit they skip a lot less sync points so its smoother
also they recorded their cines in a lower fov and spent more time on them for sure
and for a final note it seems like ur only changing the volume of sfx instead of distorting them, which can make ur sfx just sound way better
edit: o also learn how to use s_shake its the best shit ever
