ffmpeg version 7.1-essentials_build-www.gyan.dev Copyright (c)
2000-2024 the FFmpeg developers
built with gcc 14.2.0 (Rev1, Built by MSYS2 project)
here's my syntax:
ffmpeg -i $1 -c:v libx264 -crf 20 -c:a copy h264-$1
you can clearly see the guitarist's face is much wider after h264 processing
am i missing something obvious!?
p.s. note the default help syntax doesn't work in v6.0 nor 7.1 (this
is the command listed in https://trac.ffmpeg.org/wiki/Encode/H.264) :
ffmpeg -hide_banner -f lavfi -i nullsrc -c:v libx264 -preset help -f mp4 -
x264 [error]: invalid preset 'help'
Well overlaying both images on top of each other clearly shows the face
did not get wider, however because the transcoded image lacks some fine
details it appears to look wider.
