How to Prevent White Fade-In/Out?

I have a Captivate 5.5 project with a single slide that was captured by full-motion recording. When I publish the file as an MP4 the video starts with a blank white screen with a 1-sec. fade-in to my actual content. One second before the end of the MP4 the video fades to white. I don't want this fade-in/out effect. The single slide in the file has no transition. When I scrub from the beginning to the end of the slide there is no fade effect. I can't find any file or publish setting related to a fade transition. Where is this coming from? And how can I get rid of it?
