now I somehow I have to move them to a vertical strip. Might use imagemagick or ffmpeg… hm.

going to try:
ffmpeg -i front%05d.tif -i right%05d.tif -i back%05d.tif -i left%05d.tif -i top%05d.tif -i bottom%05d.tif -filter_complex vstack stacked%05d.tif
probably won’t work but i’ll try it.

ok. It stacked the 1st two. So, I’ll do two at a time:
1)
ffmpeg -i front%05d.tif -i right%05d.tif -filter_complex vstack 1_stacked%05d.tif
2)
check.
3)
If it works, then
del front*.tif
del right*.tif
4)
ffmpeg -i 1_stacked%05d.tif -i back%05d.tif -filter_complex vstack 2_stacked%05d.tif
5)
check
6) if it works,
del 1_stacked*.tif
del back*.tif
7)
ffmpeg -i 2_stacked%05d.tif -i left%05d.tif -filter_complex vstack 3_stacked%05d.tif
8)
check
9) if it works,
del 2_stacked*.tif
del left*.tif
10)
ffmpeg -i 3_stacked%05d.tif -i top%05d.tif -filter_complex vstack 4_stacked%05d.tif
11)
check
12) if works,
del 3_stacked*.tif
del top*.tif
13)
ffmpeg -i 4_stacked%05d.tif -i bottom%05d.tif -filter_complex vstack 5_stacked%05d.tif
14)
check
15) if works,
del 4_stacked*.tif
del bottom*.tif
and I should end up with properly vertically stacked strips for pano conversion.

YES! IT STACKED!
now to try the pano2vr again.
