.mp4 is a container, not a codec. It may contain H.264 but with XDCCAM EX it contains MPEG2.

That's a very broad question.
Generally the camera supports XAVC Intra which is I frame AVC based which may be around 100mbps depending on frame rate
XAVC-L which is a GOP based AVC codec which may be 50mbps or 35mbps
MPEG HD422 which is related to XDCAM HD which is MPEG2 50mbps CBR
MPEG HD420 which is related to XDCAM EX which is MPEG2 35mbps VBR
AVCHD which is AVC GOP based at consumer bit rate of 28mbps or 24mbps

But you can find more detail in the spec sheet. It's not clear at all what info you need and why though.

A test I ran showed the XAVC 1080P L GOP, 50mb/sp was better in detail, higher resolution than the MPEGHD 422 setting. Example was outside, grass, showed better detail.

Adobe stuff... Premiere Pro CC 2015 etc. and even my old FCP7 XDACM import seems to work with them too. I've just started using the X180. I guess it's the same as the X160 but with WiFi

Don't know what kip or vic is...
