Hello,
video recorded for 4/3 :
Stream #0:0[0x100]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002),
yuv420p(tv, bt470bg, top first), *720x576 [SAR 16:15 DAR 4:3]*, 25
fps, 25 tbr, 90k tbn
(container ts).
What I want to have is something like that :
Stream #0:0[0x100]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002),
yuv420p(tv, top first), *720x576 [SAR 64:45 DAR 16:9]*, 25 fps, 25
tbr, 90k tbn
Did some tries with -vf scale=720:576,setsar=64:45,setdar=16:9 or
something like that. But the result neither have the expected size nor
the video quality will be acceptable.
To resize the video via TV-settings will be possible, I hope the
transformation will also be possible without reencoding.
Any idea what to do ?
Best regards
Richard

What I have : 720x576 [SAR 16:15 DAR 4:3]
What I want : 720x576 [SAR 64:45 DAR 16:9]
What I get if I use -vf scale=720:576,setsar=64:45,setdar=16:9
will be the following : 720x576 [SAR 221:125 DAR 221:100]
Therefore the question, what I must do, to get with -vf the following
result : 720x576 [SAR 64:45 DAR 16:9]
There is mothing to crop.
Best regards
Richard
