I'm having a weird problem with my keyframes.

I am making a video that has fast zoom in's and out, like frame 1 = 750, 600 - frame 2 = 960, 540  - frame 120 = 960, 540 - frame 121 = 750, 600

And when I do this with out any easy ease just default keyframes between frame 2 and 120 the footage just moves in a direction then comes back to the position I set it to.

This is my problem - Screen capture - d052f9cacfda18b2727c073a66d6ba18 - Gyazo

    The better solution is to convert the keyframe where the pause is supposed to begin to a Hold Keyframe. In this case, it looks like the second keyframe - select the keyframe and Hold Down the CTRL+ALT keys while you click on the keyframe. You can also use CTRL+ALT+H to toggle a keyframe to/from a Hold Keyframe. This method allows you to retain the integrity of the original Motion path.

    it's a common overshoot problem that can occur when dealing with spatial keyframes. it can seem very weird. we have a name for it in Ae - the Boomerang effect. AE Keyframe Boomerang Effect, Part 1 - YouTube

    to fix it, select both keyframes and press Ctrl+Alt+K to get to the keyframe interpolation dialog box. change the spatial interpolation to linear. to avoid these complications in the future, you can change Ae's general preferences to "Default spatial interpolation to Linear" by check mark the check box .

        Roland is right, not by it being "Best" but in describing a scenario and solution where you want to maintain the bezier curve motion path. toggling Hold (as demonstrated in the tutorial I posted) is only necessary if you actually need to keep the bezier spatial interpolation. but, most often than not, this overshoot issue will get you in just plain linear movement that you want to keep still between two exactly the same parameter keyframes.  by looking at Op's screen capture and reading the description, it appears to be the case i.e it's not a curvy motion path you want to maintain, but simply want the keyframes to stay where they are and not create bezier handles in space when they are not needed.
