Video view is set to fill screen:
When rotating video view by 90 degrees, the dimensions do not get updated.
Thanks for the bug report. 
Could you tell me which target platform(s) and version of Fuse you’re using?
Sure!
Version: Latest (.23) Platforms are Android, iOS
Thanks again.
Yes, this sounds like a bug, I have created a ticket for this.
Hi!
How do you rotate the <Video />? If you do it by changing its transform then it will not change its size. I think what you would want it to be able to change the orientation of the video. That is a feature we do not have yet
