You need video editing software and a powerful enough PC to edit videos. Crappy i3 based lap tops (with a low-power processor to have a large battery life) tend to not do this very well. (You are basically trying to tow a large boat with a Yugo/Mini-Cooper) (sigh) Install Windows movie maker.
Then shoot some test footage with your video camera then try to import the clips and arrange them. This is the only way to tell if your laptop will work.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
