Hi Guys,
I am a total novice so forgive the ignorance. Here are 2 of the problems I am facing with my new Adobe Premiere Elements 8.

1. I don't know how to trim (not sure if this is the right term) my videos. I don't want to portray the whole screen captured but just a part of it. Eg. I took a video but I just want to focus the upper left side. How do I cut out the rest of the unwanted area?

2. This is my biggest problem. When I import my high quality .AVI files into APE8, the video quality goes down extremely. The pixel size as well as the whole picture quality is lowered. I tried rendering each video in the timeline but didn't help. How do I get over this?

Thanks in advance.
