Newscast Movie

We are going to use a movie that requires two special effects. Using a greenscreen to filter out unwanted background and the picture within picture effect, where a small picture shows in the corner of the screen. This is the first time you have been required to use a special effect, although several of you have used one by choice in a previous movie.
Using special effects in Adobe Premiere starts easy. You just make sure you have cut the video into the section you want the effect on and then drag the effect onto that section of the video. Then you use the effect control window to make the settings you need for what you are wanting. For example you have to tell the greenscreen effect exactly what color to turn invisible so that the picture or 2nd video behind the 1st starts showing.
Many of you are still trying to finish up the last movie because you put off editing too long. Hopefully you won't make the same mistake with this movie. What do you think about the newscast movie? What problems did you have with the last movie and what could you do different this time?
