[help] another delogo try - samples

[maudit]

Hi, it's me again with another logo.

in this link there are: the mask, the script, the original file sample, the encode sample.

https://www.dropbox.com/sh/pl6sg6u3ome31pe/AACoTrhjoVKqjX7PMLDRGeEMa?dl=0

The logo remnants/artifacts are barely visible in some scenes, pretty invisible in static scenes and much visible on moving/dark scenes.
as a whole is not very good to see.

I would like to ask, is this the better result I can get or I can do it better?

You can't do better on this source.

I have no doubts, but just for understand the reason.
is it because the source is 576? or cause the logo is poorly designed?
cause the logo is not so much transparent?
what is the reason?

Because video is not high quality [lower bitrate] when logo's transparency is low.

fine, thx, i got it.
you have to imagine that the same movie downloaded from the TV website where they stream it, is even worse than this DVB capture.
