I can confirm 2) mp4, because I just testet rendering the same hdv clip 
to mp4 without any Setting > Format preset or user defined, mp4 displays 
correctly with SAR 4:3 DAR 16:9:
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, 
bt709/unknown/unknown), 1440x1080 [SAR 4:3 DAR 16:9], 9132 kb/s, 25 fps, 
25 tbr, 12800 tbn, 50 tbc (default)

Yes, I would be thankful if you can upgrade the previous 
cin-aom-38_svt.AppImage ....

Do you possibly have any clue why Igot all those startup error messages?
(AppImageLauncher:4019): GdkPixbuf-CRITICAL **: 11:01:03.063: 
gdk_pixbuf_get_pixels_with_length: assertion 'GDK_IS_PIXBUF (pixbuf)' failed

These post did report similar messages (though not identical)

I asked about similar messages once upon a time previously, I don't 
remember if it was a test  version, but they disapperared.
What I can see is that the testversion has a theme with darker black 
screen and sharper green color on the gui buttons ...

Tubleweed-Slowroll currently has Kernel 6.6.3 and Gnome 45.2 desktop 
(newer than on Leap)
