Remove HUD from video but keep frag msg's?

I've read up on the settings for converting demos to vidoes but I can't find a way to remove the HUD but only leave frag messages on the screen.

viewsize 120 and r_letterbox -1 remove everything on my system.

Create a seperate config for videos and remove all HUD panels, either via the Editor or console (hud_panel_*).

Ok will try.

OH. I forgot:

The frag message is part of the HUD! So you got to leave that panel of course.
