Video that "disappears" on my slide

Hello,

I'm searching for help on a project of mine which includes slides with videos.

On my slide, the video must begin (be played automatically) when the slide is launched. Then the video must "stay still" in background so I can add some text and stuff on top of it (I also need to add triggers).

My problem is that when the video is finished, it "disapparear" when I click somewhere on the slide. I tried to add a rectangle on top of it, with a lot of opacity, just to prevent the possibility to click on the video, but it's still doesn't work...

Do you have any idea why it keeps disappearing when I click ?

The project is in attach file.

Thanks,

Auriane
