Is it possible to render out of Matinee in 32bpc?

As far as I can tell it seems like Matinee render output is 8bpc only. Is there a way to get 32bpc full-floating point renders? Even 16bpc half-float would be great. I am looking into using UE4 to render animated films and this is something of a deal-breaker for me as I like to do a lot of post-production and 8bpc isn’t really sufficient in a lot of cases.
