Editing - Problems and challanges

Since starting my editing process I have came across a few problems not just with the software but also my actual work. The problems with the software are minor and do have a way round them with a bit of work. This can include placing clips in a certain place, but then they move. This can be irritating as the clip won't be where I want them. However by using different tools in the programme there is a way to place clips where you want. Furthermore another problem that has occurred within the class to do with the software is that its new to our school, so were not as confident using it compared to last year, when ourselves and the teachers new almost everything about it, making editing a smooth procedure. This can be seen as sometimes other members of my class believe that their work has disappeared, when actually it is not, but rather were not aware of how to get it up. Despite concerns regarding the software, one of the main ones have also concerned my editing. For example I originally was not cutting my clips to the beat, making my video appear to be slightly longer than need in certain areas. However I changed my clip arrangement, making it fit into the beat, and it now does look better. The final challenge which I have faced with editing my clips is that I originally had the idea that it would all be in a negative type effect, but this has not looked very good. Therefore I have to come up with a another idea as to make my video visually impacting.
