I am a pretty new user of Final Cut Express HD and I'm having some issues with a project I'm working on. I have rendered the project and when I try to export as a Quick Time movie, it will start to write the audio and video and then it gives me an error message that says, "File I/O error." When I try to export with "Using Quick Time Conversion" option, no matter what kind of file it is, it begins to write audio and video and when it finishes and I watch the file, and the audio is there for about half of the total video time, and the video is just a still frame of one scene in the project? Any ideas or helpful hints for me to try?
