CODEC Error when exporting from Timeline solution
This is a stupid mistake, but when I was just in Final Cut Pro 7 trying to "Export Using Quicktime Conversion" I got a "CODEC Error" message and couldn't export. I tried changing the CODEC in my Sequence Settings, still got the error, I started freaking out thinking I had to delete the preference files; but I suddenly realized I had the "In" marker at the end of the video on the Timeline.
Solution: "Clear IN and OUT" markers on the Timeline (right-click on Timeline, Clear In and Out).
Check the simple things first! lol
