I’ve been dealing with Avid support on this for weeks now.
We tried both Symphony and MC at 6.0x and latest 6.5.
We are getting the same black screen result in QTX.
However, I can see the results in QuickTime Pro 7, but only with exports of 20 minutes to 25 minutes.
Anything above that say 2 hours will show the first few frames in QT7 then green after.
You can hear the audio but no video.
We tried this across 4 computers and still no go.
We then tried to replicate this issue with all Adobe products.
None of them support QT REf?
On a side note, the issue also occurs with Share to Sorenson from all Avid software.
Rather annoying bug 😛
