If you have an example, I'm interested.

ffmpeg -i input.mp4 -c:v libx264 -filter_complex
"scale=640:-1,split=2[v1][v2];
[v1]crop=200:306:456:0,lutyuv=y=val*0.75[brightpart];
[v2]lutyuv=y=val*2.5[darkpart];
[darkpart][brightpart]overlay=x=456:y=0[v]" -map "[v]" -c:a copy
-threads 2 -crf 20 -f mp4 output.mp4

Thanks much!
