I've never used Final Cut Pro before therefore I wasn't sure where to start or how to go about using this editing tool. I found both "eHow" and "Wikipedia" helpful for the breakdown of information. I also felt that trying out the actual tools independently in Final Cut Pro proved to be helpful.
eHow:
I found a few of these "How to use..." videos helpful as a beginner editor.
Trimming clips is probably the easiest thing to do whilst editing and doesn't take too much time. I found that experimenting with Final Cut and watching tutorials very helpful. A problem I found while trimming clips was perhaps trimming too much or not the right clips.
Importing clips is also another simple job as you can select a whole lot of clips and import them straight away. I didn't really need to view this tutorial but watched the clip to make sure I was doing the right thing.
I found applying transitions quite difficult as I am new to Final Cut but it wasn't as difficult after watching the tutorial. I felt that the transitions our group had decided on weren't going to be difficult and I felt confident in making the transitions look well done.
