Cube converter issues & recommendations
Im in the process of converting to 'Flash'
Ive been laboriously converting my equirectangular tif images into
cube faces with dosup then individually saving them to jpegs
with 'save for web' in photoshop (6)
So now Ive just tried pano2qtvr to convert which works great except
the jpg converter gives definitely less quality for the same file
size (patchy areas in plain areas of the image at high compression
Are there any ways to fix this or what about other converters? Any

is even slightly smaller than that.
I just tried making a mov and a set of cubefaces from your TIFF
image. I took the liberty of patching the zenith and nadir (sorry,
force of habit! :-) although I didn't labour over this. I used
Pano2VR to make both the QTVR and cubefaces at 1500px, with JPEG
quality at 60% - more than I normally use, but this helps with the
plain walls and delicate shading.
The results came in at just over 930KB. You can see the mov at

cubefaces from http://www.panoramaphotographer.com/bar.zip
If you're a Windows user then Pano2VR is probably one of the best
modern solutions for creating your cubefaces. Don't generate faces
larger than your input image can deliver, and treat the compression
for each image as a separate case. You'll find that many will work
fine with a particular compression level, but don't assume that all
