Transform Key framing - inconsistent timing

Trying to use the transform scale keyframes to enlarge the size of a title. SO It gradually gets bigger and goes out of frame. however when I transform it from the 100% to the 4000% percent I need to for it to be large enough to go off screen the timing is drastically different. Like it will enlarge really fast between the 100% - 900% and then slow down drastically between the 900-4000%

Any insight on how to fix this?

That's the Ease In/Out function. On movements, you can control that a little bit, but on the scale, there's no control that I am aware of.

The only function I have ever been able to control the easy ease function on was opacity.

It works in Position.

Not at home, so I can't test this workaround: alt+g / cmd + r / shift + b / drag.

Isn't there a title zoom in (or so) whose published parameters allow to disable ease out?

However, feedback time.

I've been requesting smoothing controls on all keyframable things since 10.0. They don't care. They're not going to implement it. They would have implemented such a basic thing by now if they had any interest in it. It just so happens that they're not interested in doing it.

That said, they want you to use Ken Burns. I dunno if Ken Burns has it in his contract that only HIS scaling feature can have smoothing in FCP and no other. That literally is my only guess. I wish Ken would give us rotation abilities. Trying to use rotation along with Ken Burns' thing clips harshly and giant black boarders result. Anyone know Ken's phone number? I wonder how much Apple paid him to use his name. I wonder if it helped sell any copies of FCP. I mean I'd use it even it f it were called Bob Evans or Scaling and Movement Thingy.
