(I am still curious how / why you get bgra video: 
Is that ray-traced material containing transparency?)

Why don't you use libschroedinger instead of rawvideo in 
this command line if your goal is to get dirac in avi?

(The real question is why you want to use yuv444 dirac: 
dirac usually has no advantages over other codecs, if you 
need a lossless codec, try ffv1, it also supports RGB.)

Concerning your command line:
yuv444 is not defined in avi (if you have a counter-example, 
please share it!), use nut if you need to store raw yuv444p 
in a container (I do not think that is what you want to do).

And please note that if you are a user, current git head is 
always recommended.
