hello russ
that was fast. thanks. did exactly as you asked, and the results worked like a charm. nice, elegant
but there's a critical problem: it seems as if the .ac3 file was stereo encoded (mixed down) in the resultant QT output. this is exactly what premiere cs 6 does. i was wondering if the same is true of final cut x & compressor? i need a QT playback device to recognize the embedded audio as an .ac3 (dolby digital), and not LtRt or stereo track. any ideas?
here is the header info from the merged file exported through mpeg streamclip:
