We speak about videos, again give me an example of your not lossy video world.
Harald makes a fair point. The definition of ‘lossy’ is that you will loose
quality when going to a ‘lossy’ codec.
Now end this pointless conversation and start helping the OP please.

Its a trivial point, to say without lossy its not possible, we live in a
world of h.262 (DVD), h.264 (HD-TV) h.265 (UHD-TV), all are based on
lossy codecs. Its only a pointless discussion for people who live in a
not lossy world.
Also a hint by ffmpeg wiki :
H.265/HEVC Video Encoding Guide
This guide focuses on the encoder libx265 which can offer around 25–50%
bitrate savings compared to H.264 video encoded with libx264, while
retaining the same visual quality.
refer to https://trac.ffmpeg.org/wiki/Encode/H.265
Back to my question, ..."while retaining the same visual quality." by
compression with h.265, which ffmpeg parameter to use to compress h.262
videos ?
