I created a movie in 1280x720 project with 720p footage. I added some animations to the wall behind the narrator. I put animations in precomps. My precomp compositions have 1920x1080 dimensions. 

Customer called me and they say they want 1920x1080 version of it. They'are sending 1080p footage now.

Now i need to scale the corner pinned precomp layers to fit 1920x1080. When i scale my precomp from 100% to 150% it fits correct position and size but looks blurry because "continously rasterize" must be off.

Corner pins have no keyframes, camera is fixed (has a lot of different angles) but i have hundreds precomped animation layers. I dont want to fix corner points one by one manually.

I tried to change corner pin point positions with expression but I couldnt solve it. 

Do you have any idea about to fix it? If you know a solution share with me and save my night :)

Thanks a lot and have a nice year!
