Do you think it is better to adopt SampleAR which is congruent with
Info --> Detail.
Or is it better to PixelAR which is the one used by wikipedia and
every other guide I found?

Well, I would go for FFmpegs SAR. That is the simple and informative
table from ffmpeg-users, (complemented with HDV by me):<br>
<a class="moz-txt-link-freetext" href="https://lists.cinelerra-gg.org/pipermail/cin/2024-January/007800.html">https://lists.cinelerra-gg.org/pipermail/cin/2024-January/007800.html</a><br>
<br>
I suggest also to a cross reference to Wikipedia that lists PAR/SAR
opposite, but also refers to FFmpegs way:<br>
<a class="moz-txt-link-freetext" href="https://en.wikipedia.org/wiki/Pixel_aspect_ratio#Confusion_with_display_aspect_ratio">https://en.wikipedia.org/wiki/Pixel_aspect_ratio#Confusion_with_display_aspect_ratio</a><br>
<br>
<br>
My reasons are that SAR is what ffprobe display when we check video
files (and is also used by ffmpeg setsar), for example:<br>
<br>
4:3-576 PAL DV: <br>
Video: dvvideo, yuv420p, <b>720x576 [SAR 16:15 DAR 4:3</b>], 25000
kb/s, 25 fps, 25 tbr, 25 tbn, 25 tbc<br>
16:9-1080 HDV: <br>
Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, bt709,
top first), <b>1440x1080 [SAR 4:3 DAR 16:9]</b>, 25000 kb/s, 25
fps, 25 tbr, 90k tbn, 50 tbc<br>
<br>
In CinGG I think we concluded there is no way to set user defined
SAR or control Presets in Set Format. CinGG is dependent of to set
Preset for a different output anamorphic format (using SAR coded in
ffmpeg.c), if I understood things right.<br>
