Hi Hans
If I understand right, in CubicConverter we have to preset
the compression.
(Maybe my panos are also bigger than needed)
Which one is the 40%-standard?
In CC I find only find the settings in words, like
QT-VR Panning quality for Motion - normal
QT-VR Panning quality for Static - high
There are some more settings.
Could you please explain, which settings are the best.
(high quality and small file sizes)
Thanks
Rolf
