Youtube Video Background with start at specific time (e.g. #t=1m02s)

Hey,

i tried to change my actual background video with a new one, but this needed to be start at a specific time. So i found out that i could arange that by adding sort of this code to the URL : #t=1m02s. But this won’t work for the Background edition, just stayed black screen.

Thanks for Help!
