I may be missing something, but I don't see what use a lens profile would have for gyro stabilization? What's the thinking here?
The gyro data is useful, and its already producing pretty good results, but how much correction you need to apply to the image is drastically different on a 8mm lens, then it is on a 200mm lens. If you rotate the camera 1 degree on an 8mm lens, you might not even notice, but on a 200mm lens, that is a lot of pixels that just shifted location, that need to be corrected with the stabilizer. So perhaps a full on distortion profile etc might not be needed, but just knowing what the focal length of the lens was could help a lot to get even better stabilization.
The reason a profile would be useful instead of just entering the focal length, is that not every lens of the same focal length produces the same image, some 24mm lenses, behave more like a 25mm lens, and some behave more like a 23mm lens.
Not sure if profiling lens distortion matters or not, since I am assuming black magic is is essentially just panning the image around to counteract motion, so its possible these "profiles" could be very basic and easy to do.
