Issue using time remapping and motion effects on the same clip

Hi all

I'm new to premiere and editing at i've run into a problem i can't seem to get around so i'm here for help.

A bit of background to my issue.

I have a timelapse clip that is is about 45 seconds and i want to speed it up using the time remapping feature so that the clip reduces to about 3-5 secs so everything is moving really fast. At the same time i want to pan the clip from left to right using the position function in the motion effects. I have increased the scale so the clip is zoomed in enough to accomadate the pan.

I started by selecting the clip and applying time remapping so i reduced the clip length to the size that i want. Then i added keyframes on the position motion effect at the start and end of the clip (from 1147 to finish at 772). When i click play the clip plays at the speed i want but no pan. I remove the keyframes and try again multiple times without success. Weirdly though every time i would play the clip with keyframes i can see the postion x axis number changing from 1147 (start frame) to 772 (end frame) as if it should be panning across the image but i'm getting a still frame.

i decided to reverse the process and delete the clip altogether and start by adding the motion effect keyframes first. This time i'm getting the pan effect i wanted but i can no longer reduce the clip from 45 seconds to 5 using time remapping.

What am i doing wrong? How do i get both the motion effect and time remapping to work on one clip?

sorry if this has been discussed on a previous thread, i was unable to find it
