I just did a trailer where I edited the video and had to do the basic sound design layout in Resolve 16. I finally figured out the best way to export the AAF, (I exported the file as ManChicken recommended) and the music that was sent to me as mp3 files did not export with the AAF. All the other files were 48khz 16 bit WAV and they exported with handles, and the best part was the clip volumes actually transferred! I went back and converted the mp3’s to 48k and voila, everything worked. I can’t tell you how cool it is to build the rough cut sound in Fairlight, but then have it transfer with clip volumes to Nuendo. The basic mix I did in Fairlight for approval wasn’t lost. Can’t do that from ProTools without turning clip gain into automation. I think Fredo is correct in stating Resolve wants everything to be the same sample rate in order for it to properly export the AAF.
