  • Saving from Mac to Windows creates unsupported media error

    Posted by Chad Gilmour on April 7, 2016 at 2:56 pm

    I can build a simple project on a windows, open and save it on a mac, then open it on a windows and it will produce several errors:

    “After Effects Warning: Error with file: ‘\Volumes\Media_Drive\xxxxx.mov’.
    “After Effects Error: File “xxxxx.mov” cannot be opened, it may be an unsupported format.”

    It will do this with everything, mov’s, .mxf’s, jpegs, png’s, illustrator files, etc.

    The worst part is it can’t even be relinked via right clicking and selecting replace footage, that will produce the same errors. However I can find that assets, import it into the AE project and then alt+drag replace the media in the timeline, so I know the media type IS supported, but when the file comes from a Mac, AE thinks it isn’t supported and I literally have to rebuild the project.

    Anyone else have this issue or have a workaround for this?

    Using latest Adobe CC, Windows 7, Mac El Capitan.

    I’ve figured out that I can save a project file as an XML, alter the file paths from Mac to Windows, and it will open perfectly fine in Windows. I’m working on a script to do this for me, but what a dumb work-around, there’s got to be a better way to not run into this issue.

    I don’t think it’s necessarily an El Capitan issue because I get the same issue when a file saved from Yosemite too.

    My current bandaid is to open the .aep file, save an .aepx (XML) file, then run script on it that converts the filepath code to windows. That seems to do the trick for now.
