White appearance when switching from one slide to another in a video export

Hello,
I have a project with several slides. Each slide contains video, audio, and various animations.
I export this project as an MP4 (i.e., video), and when I play the video, there is a blank space that appears. This blank space corresponds to the slide change. How can I prevent it from appearing?
Thank you for your response.
Have a nice day.
