I recently purchased a new iMac - 3.1 Ghz processor with 4 GB hard drive. I'm working on a project with stills and lots of filters and effects. The project is about 3 minutes in time. I'm getting a dropped frame message quite often while working on the project. I have unchecked in user preferences the selection that warns when a frame is dropped, but that has not helped.
If anyone has any suggestions, it would be appreciated. Perhaps the compressor?
