New description:

 currently, i use this, however, i am unable to run it specifying points in
 curves. Is any option to use a gnuplot file directly? or to extract
 smplayer options on brightness, gamma etc. to use them with ffmpeg
 somehow?

 for vids in *.avi; do ffmpeg  -hwaccel vaapi -hwaccel_output_format
 yuv420p -vaapi_device /dev/dri/renderD128 -i "$vids" -vf
 'curves=preset=lighter,setpts=2*PTS,format=nv12,hwupload,scale_vaapi=w=2560:h=1440:format=nv12'
 -strict experimental   -c:v hevc_vaapi  -b:v 20M -video_track_timescale
 90000  "a_${vids/.*}.mp4"; done;

 debian trixie linux,
 ffmpeg version 7.0.2-3
