A place for Adobe Premiere Pro editors to learn their craft. An unknown error occurred during project manager operation. Re: Project Manager 'Unknown error' Premiere 2014 mloucks83 12:18 PM ( in response to Trent Happel ) As is the case with the OP, we use a variety of formats, but generally it's either Pro Res 422 or XDCAM. For example, the destination file can also be in use as an input file for another operation.
Destination file is in use by Premiere or destination file is in use by Adobe Media Encoder.' An application is using the destination file.
