Noob here, but I just created a video using the simplified "Wizard" interface. Imported all of my clips and individually trimmed most of them. Got to the end and realized that there were more things I wanted to do than the simplified Wizard let me do, so instead of saving to a file, I chose advanced editing, which opened up my project in the normal interface. For some reason, most of my clips are now duplicated with overlap. So, for example, if I started with a video clip that was 60 seconds long and I cropped it to 30 seconds, it now shows up as two 20 second clips - both from the cropped 30 second clip. In other words, it will play the first 20 seconds, then jump back 10 seconds and play the last 20 seconds of the same clip. These are saved as 2 separate clips. This was a rather large project, so I'd REALLY like to know if there is a way to fix this other than just starting over.
Thanks in advance.
