When I export a QT Reference from Avid Media Composer 5.0 I just get a white screen when I open it in TMPEGEnc 4.0. This also happens when I export a higher resolution QT file. I finally was able to get video by exporting a reduced size QT file. What is the issue? It seems to me I have been able to export QT references and bring them into TMPEG before.

Thanks
