HDR Screen/object motion blur

Hi all, first post.
I wonder if at least one of these is possible to implement? Would be very nice.

Object motion blur requires a velocity buffer, which only a few games create and in those it's still pretty much impossible to identify it genericly.
I'm not sure what exactly you mean with "HDR Screen". A backbuffer format with more than 8 bits per color? There are plans to allow forcing one which has 10 bits per color (that's the highest possible currently with onscreen rendering), so yeah ...

By screen MB I meant simple camera rotational blur

Like this ?

That works too I assume it's not based on velocity?

Nope, as said, no way to genericly retrieve velocity information.
