Thank you for taking a look at the problems!
Yes, the originals are from a S2 in 12 MP mode and a Sigma 8mm

Most cubicals are converted from a 4000x2000 equirectangular with PanoCube.
Normally a jpeg-compression of max 75 turns out to be more than
sufficient, wich gives me filesizes of max 1,4 MB.
In this case settings are partly 'upgraded', e.g. the Mirror Room uses
6000x3000 input and a jpeg compression of (95 95 95 95 90 80) for the faces.
Big problem is the noisy input (Mirror Room: Light ~60 Lux, shutter
speed 15sec). Unfortunately, removing the noise ends up in very
'artifical' images and high compression ends up in a blurry panorama. A
good indicator are the red chairs on which i experimented the current
settings.
