warp stabilization render problem

Hi,

I would like to ask if it's possible to render (export) in the same quality after warp stabilization like the original file? (shot with 5D 1920X1080 25fps)

Itried with best settings, lossless

with current setting, lossless

same settings as composition, lossless

but all seem to be uch worse quality than original file. If I open it for editing in FCProX or Premiere still worse than the orginal next to it.

Thanks:)
