I was editing a video for youtube yesterday and everything was fine, I had no problems what so ever.
I opened up sony vegas 13 this morning and in the Preview Window was a little red circle that had the text "FLAT EQ"?. I do not know what this is put its not going away, I thought it was to do with the Audio if the gain was too high or too low but I've changed it and its still there.
