Output XDCAM footage with kdenlive

[Jogchum Reitsma]

Hi,

I want to ship a series of short movies to a local broadcasting station, 
which expects the footage to be

XDCAM-EX 35mbps 1080i50

but I can't find it in the kdenlive profiles. Melt has it, or something 
close to it, though, in XDCAM-HD422.

How can I select those mlt-formats?

regards, Jogchum Reitsma
