In Preview mode, Video dimensions shrink on Play

Hello,

I noticed the issue on transitions, my background item (map) was jumping :

- first artboard : a video playing (zoom in on a map)

- second artboard : screenshot of the viewmap (exact same place / size) where I want to add some interactions and components (roads, data, etc)

So to simplify the problem, and check if I can or cannot do or repair something in my projects, I activated "Press to Play" on the first artboard. It's not the expected behaviour for the final product, but it will be useful to explain the bug.

The initial context (context.jpg) : video is perfectly aligned on the left side and fits the entire artboard

In preview mode (offset_1.mp4) : when I click to play, video shrinks about 7~8%

Please, help !

Regards
