Xbox videos app

[FAHMI BASSEM]

Hi, I've Lumia 720 runs 8.1 , 5 minutes ago I installed the video editing app by Microsoft, I wanted to check my storage, I found that there's 1.6 GB of videos on my device, when click on manage the video app shows nothing!
I want to ask the videos in my photos app ate the 1.6 GB?
Thanks
