Beginning of the Year

In the christmas holidays I have finally recorded all (hopefully) of the footage that I need to make my horror film trailer. What I know need to do is edit all of the little scenes that I have recorded, put them all together and add simple black backgrounds with text on. I am thinking that this will take me quite a bit longer than the previous two tasks that I have had to complete, both in which still need a few tweaks. The reason that the horror film trailer will take a lot longer is because this is my main tasks, whereas my other two tasks are ancillary tasks. I also believe that this will be the hardest task that I will come across, not just this year but including last year as well.  I have never used this piece of software before, and even though I have watched a few step by step videos on how to use this complex piece of software I still think it will slow my progress down.
