It seemed a tad bit laggy in some spots
I Didnt noticed any sync
There was no cc
Its almost like you just put replays over the music.

Yeah. agreed what Kolorz said.

This was like a shitty remake of a perfect and a smexy vid, with shittier editing and replays.

1.Learn keyframing(if you do learn how to smooth them out)
2.how in the fuck is this an edit at all.
3.Get better replays(hint hint)
If you do this your videos will become better.
also
bro.
There are way better recording programs and editing programs out there.

I don't think "5CE" is a thing
I don't know if there's any sort of "markers" like there are in sony vegas, but you should set a point somehow to let you know where you want sync in multiple places, and see where which point works best without slowing the clip down to like 2 fps.

Hours used this song, by the way.

i think you may have been a little too inspired, you kinda copied what he did with the effect, but you used xray.

also, there was no sync that i could notice and the keyframing was horrible.
try to keep your tori inside the window, not zoom in on his ass like 0: 30

keep the tori centered, maybe move it around a bit, but it does not look visually appealing when the tori is almost all offscreen.

tip: For the love of god do not use imovie. at all. i use final cut pro for all of my edits, its way more advanced than imovie.
