Now I have found how to output AVC/H.264, but Nuendo only imports the audio. Video is an empty track and the audio-files must be searched/reconnected. If I import video with „import/video“ menu it works.
It‘s on a NAS not with a device-letter like x:
My path is \NASNAME\directory\filename
I checked an import of AAF in Edius and it works. Seems, that AAF-import in Nuendo has problems with NAS and UNC.
To the mov I have to check. There are several output-formats hidden in an extra dialog named „Details“ in Edius.
I think, that I have to choose „copy and shrink“, that it reencodes with the wanted fileformat. Perhaps the „copy only“ option does not reencode.
