Deleted keyframes on camera movement still being followed

So this is a strange problem I'm having that I will try to fully explain.

For example say I want to animate some camera movement over 2 seconds of time. I have my first keyframe at the start of the composition then my second keyframe at the 2 second mark with the camera moved a bit, this gives me a smooth camera movement from the first keyframe to the second over those 2 seconds.

Now where the problem comes is if I don't like how it looks and want to change the movement, if I delete that keyframe at the 2 second mark and replace it with a new one, when I play it I don't get a smooth movement between the 2 keyframes anymore as for some reason it attempts to follow the original keyframe that was deleted until about the middle point and then going towards the new keyframe for the second half of the animation.

I feel like I'm missing some obvious setting because any deleted keyframe on a camera seems to not actually delete forcing me to literally get the camera movement right the first time or have to delete the whole camera and start over.

EDIT I have figured out how to fix it but am not sure how to delete a post on here. I had to set the keyframe interpolation to linear

This is an issue of keyframe interpolation. You solved your issue by changing the interpolation to linear. The camera probably starts & stops moving suddenly, like a machine.

Well, there are two types of interpolation: Spatial & Temporal. Changing spatial interpolation to linear makes AE move things in straight lines. Changing temporal interpolation to linear creates instant stops, starts & changes. But you can MIX the interpolation of keyframes to create different results. Check it out.
