1) Only just caught up with the video you uploaded on the 14th, I liked it. You make the Animated Intro for that video too?
2) The editing is getting better too. If you try watching montages on youtube of battlefield 3, you'll get a little idea on cutting together a more agresive type of edit which works well with dubstep music.
3) Also if you want to try doing slow mo id say dont slow the footage down any further than what the camera recorded the footage at, as you ntoice with the latest video where people moving are slightly blured due to the frame rates not matching.
A good way to cheat, is to get a down load for twixor. its can be a tricky program to use, and even harder to use if you have alot of motion, but if you get skilled with it you can make fake slow mo video footage as the program (its a plug in for after effects and sony vegas) generates more frames by morphing the two frames together, it does make some noticable morphing in the end result. but skilled people can get the same result and it not even be noticeable.
4) Keep up with the videos, I am enjoying these.
