[Radiance-general] creating a good animation view file

[Tarik Rahman]

I think that's what you had before because I have the same error. I have my
keys.vf file but where does that come into when processing the frames because
in all the commands you've written below, none of them use keys.vf. Or am I
just being stupid and missing a simple point here?
