I have created a single scene video that begins with text and art elements, followed by an approximately two minute mp4 video, followed by two text frames. In total, the finished product should be 2:45. In preview mode, everything works fine, but after Creating Video, the beginning and up to the end of the mp4 video is rendered, leaving roughly the last 10 seconds of text out. I've tried many workarounds and have spent more than five hours trying to fix this issue. I have a presentation Tuesday morning, so any help will be most appreciated.
