Please provide any way of adjusting bit rates of video and audio at record setti

I bought Beelink sea I at Gearbest.
At your homepage http://www.bee-link.com/Beelink-MiniPC-TV-BOX-63-1.html  and also at Gearbest, ZIUI interface is shown at HDMI IN  for recording.  ZIUI is the interface of Zidoo x9s and x8 x10 etc.
I thought video and audio bit rates at record settings can be adjusted just as in Zidoo's products.
But in reality, Beelink sea I has no such menu as in zidoo at all at record settings in HDMI IN.
So the size of recorded file gigantic and Beelink sea I can not  use Beelink as recorder any more.
Why does Beelink company use the picture of Zidoo even at Beelink company's own homepage?
