Flash when picture is moving

[Chiogros]

Hello,

for my high school diploma, I’m going to present a subject I’ve choosen few months ago.
But as you can see in the link , in the video, I have a speedy flash of my picture when it’s moving.
Can you help me to solve it ? It isn’t good to show it the D-Day !

Thanks
PS : LibreOffice v.5.0.1.2 on Windows 10
