I have finally finished reading Adobe Premiere Pro For Dummies by Keith Underdahl. I learned how to use the color correction effects which are very useful for improving the image quality of the footage I record using my Sony Handycam which does not handle low light situations very well. Adjusting the black / white balance often significantly improves the image quality.
I also learned about compositing; using a chroma key to make a background color disappear. In other words, blue screen special effects. I use my green blackboard as a green screen but it has to be strongly lit to remove any shadows which ruin the effect. The image matte effect is one of my favorite effects. It allows you to use an alpha mask to play video within a shape. I learned how to create a picture within a picture so I can have a smaller frame of video play within the full screen video.
Other subjects I studied include audio effects, titling, adding graphics, exporting frame stills, exporting movie options, and video transitions.
I plan to study Adobe After Effects next but I need to buy a book on that. I did buy a book on Cubase SX.
