Vordio is now available for both Mac OS & Windows platforms. You should run it on the same OS that the NLE uses. This is because access to the project media drives may be required to copy & transcode media. Afterwards the converted project may then be moved to a different OS.
The free unlicensed version has a 3 minute timeline length limit for the translated project file, but ALL media for the full project will still be transcoded/copied. This means the free version can be used by a picture editor to package up the media to send to a sound editor. For long projects, you only need one license at the receiving end. See this post for details on how to use the remote workflow.
For professional sound editors please purchase a license to remove project limits.
