Hello,
Stream #0:0[0x100]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, bt470bg, top

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.cribe".
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 ?
What is your FFmpeg command line, Richard?
