hm, that's actually pretty good, nicely done
the cut and pacing in the video is great aswell. There's two things I'd improve in the video though:
- Stabilize the footage: Get After Effects or Nuke (or just pirate some CS6 After Effects idk) and watch one tutorial about stabilizing video footage, then do it for all the footage you're using. Video will look so much smoother and have a better flow with the song
If you don't mind a bit of investment, even better:
an actual camera stabilizer. Because you can't fix EVERY camera wobble digitally. Don't worry, there's stabilizers in all shapes, sizes and price classes, just do a bit of research, it'll pay off. You might not even need to stabilize it afterwards with After Effects or Nuke if you got one of these
- Do some color correction: there's also plenty videos for that and its easier than you'd think. Makes the already good footage even better. You'll also probably need After Effects or Nuke for that
Your camera buddy is already on a good way too, playing a bit with depth of focus, cutting the video with the beat of the music (but not too much). He's got the right gut feeling for quality, only thing to do now is get a liiiittle bit of less shaky videos and some color correction (or even color grading if your buddy wants to get into that aswell)
With those two you'll be able to go for a video quality that will match the music quality because to be honest: this song deserves better
Godspeed!
