Thanks GG/Phyllis for all. (last testing built 20190316).
All the aesthetic reported in this thread by me are perfect (except a little tweak on Preview pullDown, but maybe there isn't enough space, I think).

In Render-> ConfigureVideo(Audio)Compression-> VideoOptions: View, the "Kind" PullDown button shows three point. Is it right? The options are "codec" and "ffmpeg".
Thanks
