footage is moving a frame AFTER it's designated position and scale settings

[Luke7983]

These questions can be hard to write. so i've added pictures. 

i have a panning shot. 

i want the pan to END and HOLD on a certain angle (what i want.PNG). 

but after designating which position and scale numbers i want it to hold on, the next frame, the footage scoots over,(what is happening.PNG) and theres no change in the position and scale. see images. i don't know why the footage is scooting over, and i don't know how to fix it. anyone see this before?

You might want to delete the cache files first thing, to see if that changes anything:

• Start PP from it's normal desktop icon (IE: don't open from a project file link).
• Close the Open/Home screen (and you will be in PP without a project open).
• Go into Edit/Preferences/Media Cache (Mac users adjust menu name)
• Then Press: Remove Media Cache Files: and Delete...
• Select: Delete all media cache files from the system and OK
• Close PP - It will create any needed cache files on the fly as you edit.

Try and set the keyframes to linear.
