Specifically, I need to edit HD video on Windows 7.
I need a software solution which can zoom, pan and insert text. Also, I will need to adjust the scale of video clips and composite multiple video layers into the main picture (eg. zoom to a black TV screen and insert video to that TV screen).
The software can not be complex/difficult to learn (eg. After Effects/Premiere/Vegas) as I do not have much time to complete the project. However, it should be capable, unlike Movie Maker, and run on Windows 7.
So, what do you recommend?
