>From what I'm seeing, it's a little of both. When it's traversing its full range of motion, the output will "snap to" the position when it's attained. When it's moving smaller ranges (even up to ~60 deg), it seems to give a much smoother output.

Thanks Ryan,

Do you (or the OP) know if the value returned by the ptz.cgi request
is the current value of the encoders, or the target value of the
position controller.

I use to work with a Canon VBC50iR, which is the same mechanical
hardware and casing, and this thing was unable to tell me where it is,
only where it is going. This was particularly annoying when waiting to
reach a given position before taking a snapshot, and led to a
controller with a framerate of 0.5 fps...

If anyone is interested by the VBC50i ROS driver, it is available at
https://github.com/ethz-asl/ros-drivers/tree/master/canon_vbc50i

Cheers.
