I spend a large amount of my day communicating with people about RED workflow. I find that the most confusion comes from the notion that Redcode quicktime reference files are proxies.
We currently user the word "proxy" to mean two very different things. I think it's better to be very specific and only use the word proxie to mean a self contained video file transcoded from the original, whose frames map to the original frames. Thus a stand-in or a proxy.
A quicktime reference file does not work unless the raw R3D file is present in the same directory. So it isn't much of a proxy really, it's more of a window into that file, a pathway that we call a reference.
This may seem like I'm nitpicking over small things, but I notice tons and tons of conversations where there is constant confusion about what we are talking about, especially between veterans and the uninitiated. It's too much energy being wasted for me.
So my suggestion, let's start saying "reference file" when we are talking about the redcode quicktime component files and reserve "proxy" for transcoded ones. Let's add some much needed precision to our evolving terminology.
