I don't know if the AppImages *cin_svt_aspect-ratio* (Andrea) and 
*cin-x86_64 *(Phyllis) are quite identical or of same patch-levels.
But for both AppImages I used the _same_ *DV* and *HDV* source files, 
s*vt-av1* and *opus webm* rendering, without any Set>Format input from 
my side.

As I have installed TW-SR/*cin_svt_aspect-ratio*/FFmpeg6 and 
LP15/*cin-x86_64/*FFmpeg4 in dualboot on the same workstation, I have 
cross-tested both set of outputs.
In the comparison tables below,  the file names suffixed *_tw.webm* are 
rendered on Tumbleweed_Slowroll, *FF6* is ffprobe output on ditto Tw-Sr, 
while, *FF4* are ditto on LP15.

I will report differences if discovered
