Snapping Camera Alignment To A Motion Path - Not Viable

Do you still have the same problem if you turn off Overlays?

Regular canvas overlays can by toggled with ⌘/ (command-slash) and 3D Overlays can be toggled with ⌘⌥/ (command-option-slash).

If you still have problems, we need more details like: what's the shape of the Motion Path and its orientation. Does the camera have to change its angle of view? What is it flying through? etc.

I think you're right. Although you didn't provide any details, I did a lot of experimenting with it and I can't get it to behave. Although I don't get a lot of "jerky" movements out of it that you refer to, I get bizarre "flips" (the "target" turns upside down) and "snap backs" (probably related to the flipping effect) when going through simple curves regarless of the parameters I apply. [I'm still in 5.4.7 so Apple *might be* trying to improve its behavior if you don't experience the same things I am.]
