Linux bash wont run command line

Hi there
I am having an issue using muster to run a command line ffmpeg conversion on muster 7
we are trying to use our linux nodes to run the conversion
basically I cant get this line to work through muster and muster is not giving me enough feedback to solve it:
-c ffmpeg -r 23.976 -i /server/project/episode/scene/shot/shot.%04d.png -vf colormatrix=bt601:bt709 -vcodec prores -vprofile 3 /server/project/dalies/shot.mov

this should work as the command line works in bash (minus -c of course)

all it is giving me in muster is :

Use -h to get full help or, even better, run ‘man ffmpeg’

[MUSTER]Process terminated with exit code: 1

that doesnt really tell me anything, and I dont really know what is wrong
here is our template for reference

so the tl;dr question is: why wont this template run my command line?
