Hi everyone, I need to resize this composition and keep the animation, i've already searched online but didn't find anything that worked for me,cause it cuts the composition from the center and not from the layers, thank u in advace

You can parent all your layer to a Null object and scale it to resize the animation and adapt to your new composition settings.

you can use the region of interest tool to define the new border of your composition, then go to composition->crop to region of interest:
