So, you enter NOT 4 and 3 there (it will make cannas 4*1440 > width, 1080 * 3 height!) but 1.3333 and 1.0 to see dimensions go fullHD. or > set fullhd from dropdown menu and see ratio go to 1.333/1.0 Seems more like > local calculator, because ratio[] array is local to this code module and > mainwindow.C does not consult it for SAR - going purely by set display > aspect ratio and dimensions. > > > I looked at code at cinelerra/setformat.C and I am not sure how it works :) > > I will look at screenshots a bit later, now Fennec dog wants out > (fireworks finally faded away) > I also found some recent bugreports about various video software and asoect ratio https://github.com/HandBrake/HandBrake/issues/5658 see log, where it says [20:12:27] WARNING: bitstream PAR 1:1 != container PAR 9:16 so, may be we also should be super verbose and print TWO SAR values if detected, one from bitstream (codec) and another from container?
