Panning within character animator

Hey guys, My name is Claire I have created an animated series called @ThaBlock101 I have over 30 walking talking head turn lipsynced puppets with loads of triggers and magnets I created all by myself. I have attached some pictures as examples, and also a link to a music video I created also.

The problem I am having is after I export the video even at 4k and then put the video into premier pro to do panning etc. The bits that ive panned are all pixelated. If I zoom in at all even just a little it will be pixelated. The puppets and the backdrops are huge, when I zoom in via Character Animator however there is no pixelation.

There is another software called Moho in which you can record and then pan and zoom directly within the app. Can I do this in character animator? How?

I'd just really like a clean finish i've taken a long time on this project.

If I could just get on the phone with someone who knows what they are doing as I have self taught myself all of this within the last two months.

Thank you so much
