How to get a consistent camera zoom speed?

Hey! So I’ve got a scene with a long zoom in and as the zoom in continues it gets exponentially faster towards the end of the zoom.

How to I get a consistent zoom speed?

I’ve heard it has something to do with the velocity in the peg, but have no idea how to edit it properly.

If you know the answer if you could please post a step by step means of fixing this that would be greatly appreciated.

I have Toon Boom Animate Pro.

Thank you so much!
