getting crazy with ultrastudio hd mini

Hi!
I'm getting crazy with a problem...

I'm planning a live production with multiple cameras on an atem switcher, connected to an ultrastudio hd mini to record.

the problem is,

using media express, I cannot change the quality of the recording, I can just record in uncompressed way,

It create too big files... 3/4 gb per minute... that's insane!

can someonehelp me?!

It would appear you do not have other codecs installed on the computer that are supported by the device. You'll want to check the tech spec page for the product to see what codecs are supported and download/install those.
