Outputs Blanks TIFs

I tried all three methods, all three exit cleanly (0), but all three produce a white TIF. The original TIF is produced from a small 68 image test and looks fine, but the doesn’t seem to work. Perhaps I’m using it wrong:

Anybody using this successfully? I’d love to be able to get this working properly. It looks great in the screenshots.

Update: I was able to open the output in QGIS but it’s a single grey layer which probably explains why it wasn’t opening properly with regular picture viewers. Still, I expected it to be several layers like the regular GeoTIFF that it requires as input. Sadly I’m not familiar enough with Python to know where to start looking.
