Best way of rendering

Hi,
I would ask how can I get the best output if I animates imported picture (png).

Example:
Screen from the Synfig Studio Editor: s17.postimage.org/vk1dsdefz/image.png
Screen of an output (rendered to PNG): s9.postimage.org/xsh4hw6jj/image.png

Doesn’t matter output type. I just need the best quality output (in the best case as in first link). I have tried many formats of output but it’s not good yet.

I thank everyone for all the advice.

Rendering to a lossless format like png should give you excellent result.
Your second image is very small, what are your project dimensions?

I’ve solved it.
If I incremented resolution of project, exported format si much better. Thank you, rylleman.
