I created a bd.m2ts file by putting "HDV 1080i/25" as the preset.
Bd-render worked until the renderig was complete then CinGG shut down
(I don't have a BD-burner). Doing ffprobe on this video I get:
Input #0, mpegts, from 'bd.m2ts':

The video is slightly stretched and reduced to 4:3 from the original
16:9. By applying the downsample filter and setting H and V to 40 the
pixels become clearly visible and can be seen to be square.(cfr

In postimage, I have uploaded several screenshots showing the
"info--details" of the three original sources that make up the video,
of the bd.m2ts (hdv.jpeg) file, and also of how the "set format" is
automatically set.
[@Andrew, is it possible to put PAR and DAR in the Set Format window
as shown in the image?]
well, I can put DAR string in there easily, but other two fields currently NOT calculated as canonical PAR, in sense you can't put 4 and 3 there and get 1.333 horizontally stretched image ... at least in my tests??
I'll try to look harder at how it computed.
Can you please file bug about setformat window as being somewhat confusing in how aspect ratio there works?
I'll try my best to remember but *something* might distract me long enough so I start to skip on details ....
