There are no black borders in the pictures. Your player is applying
SAR to get 768x576 and then adding the black borders for your 16x9
display.

Yes of course :
... by me : There is mothing to crop.
But I agree the "Head : Remove black border ..." is not the best
formulation.
To make it complete, again :
Only the syntax must be changed : -vf
scale=720x576,setsar=64/45,setdar=16/9 then I get 720x576 [SAR 64:45 DAR
16:9]
But the video quality is very bad. I did try it with -crf 0, but this
parameter will not be used by ffmpeg in this context.
Is there a way not use somethung like that : -vcodec libx265 -crf 16 to
improve the video quality ?
Best regards
Richard
