Just found this out there on the web after much digging and wanted to share:
“In OS X 10.7 Lion the codecs need to be enabled one by one. For Sorenson3 you type into Terminal: qtdefaults write LegacyVideoCodecs SorensonVideo3 enabled”
It worked for me, I can now export Sorenson 3 from QT Pro 7.6.6 and more importantly (for me), Avid.
Cheers,
Chris
