Keyframes change values when it should not
With the 3D switch set to on, I made three position key frames with different values on the z axis: the first one has a value of -500, the second one also has a value of -500 (because I simply copied and pasted the first key frame), and the third one has a value of 1.0. Since the first and second keyframes have the same value of -500, I expect nothing to happen until the CTI passes the second key frame and moves towards the third which has a value of 1.0.
What happens is that as I manually move the CTI from the first to the second keyframe, the values change from -500 to -600 and back to -500 as I arrive to the second keyframe. What should I do so that the values stay at -500 from the first key frame to the second? Thanks and God bless.

Delete the first keyframe. That should solve your problem. You don’t need it.
If you want to know why the two values are identical and yet there is a shift in their values, in between, temporally, then it is likely due to a non-linear spatial or temporal adjustment to the out-going (first keyframe) or the in-coming (second keyframe).
It is quite obvious that you do not have a good grasp on the use of keyframes.
I suggest that you purchase the Meyers’ “Creating Motion Graphics with Adobe After Effects” book or look at one of the COW’s introfuctory DVD learning tools.
And may God Bless you too.

I agree with Roland’s explanation….however, if you do not want to delete keyframes, then you should select the keyframes, right click on one of them and then go to keyframe interpolation. Now change the spatial interpolation to linear…it is probably set to bezier, which means that it creates a curve by looking at your 3 keyframes and interpolating.
As Roland suggested, try to pick up some reading or a DVD to better understand these concepts.

Thanks guys. I saw the problem. You are right. I failed to check that the keyframes are set to Bezier interpolation.
As for why I did not simply deleted the second keyframe, the reason is this: I actually have another keyframe (which I did not mention because I thought it was irrelevant to mention) before the first one that I mentioned. So, there are actually four keyframes. The idea was for the z axis to change from keyframe 1 to keyframe 2. Then hold the value of keyframe 2 until the CTI reaches keyframe 3 (which is why keyframe 2 and 3 have the same value of -500). Then value should change again from keyframe 3 to keyframe 4.
Thanks for the help. Very much appreciated.
