HELP! distorted edges in After Effects

[mknx]

hi people.

i'm writing in hope that someone has solution for this problem. basically i'm trying to animate moving images (PNG, 300dpi) on an image background (but it can be anything, even black colour), so i change position+scale+rotate and do keyframes. The problem is - when moving, the edges of my images look distorted , i tried to render in various settings (even without COMPRESSION!) but still the same it looks quite cheap and unprofessional, and i want it to look like the images are moving on that table (background) , like they do belong do the background. maybe i'm doing something wrong ?
please help!

thank you.

Do they look distorted, or do they flicker?

Or is there a noisy edge to the image?

There could be several things going on, most likely, a fielding issue that becomes evident with these high resolution images.

You're probably not doing anything wrong, just missing a step.
