well yes, of course that's what it does. What else would it do. But it's all rather arbitrary. And incorrect, to boot. Supposing you needed to match back to a live action shot or some other software? The point here is that the focal length is meaningless without a knowledge of the format of the back plate. For example, a stills 35mm camera, 24mm is wide angle but if you were shooting, say, 4x5 plate, 24mm is extremely wide. Vue is only giving you half the information. Not really enough unless you're just playing.
