You need to set your screen recorder to a higher FPS
remove of that "Play List" thing there, i don't know much about CF, but I do know that can be gone
Record using Fraps at least 30 fps. Don't use that fire effect again because it doesn't blend in well.
Try cleaning it up to a better color correction, and try to make the movement of either the gun or the player on beat with the song you're using.
You got your render resolution right though, that's a good sign for a first edit.
