Little hard to explain but i'll try

i have a sentence which i broke up in two parts ( two .ai files)to animate. so first part comes in front the side and other one from below and move out the screen together as one sentence.
in both parts i masked out the section i do not need

so i set the keyframes as below ( attachment pictures) and for some reason one of the parts moves between two exactly the same keyframes

how is this possible, there is no camera movement what so ever..

please, it drives me crazy

You have to set the interpolation to linear for those keyframes - if you don't then you will have that movement.

There are two different ways to fix the problem of drifting between two identical Bezier keyframes:
  • Adjust the two motion path bezier handles on the incoming and outgoing keyframes. As a guide, look up the Aharon Rabinowitz tutorials on the Boomerang Effect.
  • Highlight the incoming keyframe, then use the Toggle Hold Keyframe command.
Either technique results in the same thing: the motion eases in, then remains rock-solid, then eases out.
