I have prores 422 HQ files of interviews copied off the card from a KeyPro Mini that I opened in SoundTrack Pro. File opens as a .mov and after noise reduction and limiting I save the file first as a .stap incase later changes are called for. When I render all actions, flatten and save as a .mov, the scroll bar appears and shows a save, then I get an error message saying that the file could not be saved. I am saving to a local drive with 20x the file size available. Tried saving to a different local drive, same results. Any thoughts? I am working on cleaning up the audio before the clips are turned over to the client for editing.
