Well, I would say that I just don't understand how CinGG works! I was wrong in thinking that since Info-->Detail provided the same information as ffmpeg, then CinGG and ffmpeg worked the same way with non-square pixels. Instead we return to Raffaella Traniello's guide: the definitions of PAR=pixel aspecrt ratio; SAR=Storage aspect ratio; and DAR=display aspect ratio apply. And consequently the PAR=DAR/SAR formula applies, and so does the wikipedia table. However without knowing how to read the code of CinGG I am not able to understand anything. I think I will sleep on it now... My apologize.
Maybe a reason is that FFmpeg became implementet (heavily) in Cinelerra by GG version 4.6mod or was it 5.0?
But I want to ask Andrew here: How do the Set Format Presets take care of SAR, because selecting one I can't see it, or is it behind the scene somewhere?
