Radeon ReLive Recording Encoding Type

Does anyone know how to get ReLive To display the Encoding Type..

 

HEVC? or whatever it's called...

 

I only see one Option availible...

 

Is there something I need to install on my PC to make this Option become availible?

 

Can anyone help?

 

Again, this is durring the Recording of ReLive... Encoding Types?

 

Any Help would be nice...
