There needs to be a workspace on the shared storage and a user with read/write access to it.
Use the screenshot below as reference for setup:
The default workgroup shown in Avid Interplay Access is AvidWG, which is NOT the name of the workgroup that should be used in the URI. It needs to be the ACTUAL workgroup in use, CINEWG in the above example.
The HTTP port of Interplay Services is almost always 81, but it can possibly be something else if someone had a reason.
There is a 4th button on the bottom left now that allows the user to set the head frame number, meaning which frame is selected to generate the preview for Interplay Access.
The shared storage workspace will need to be mounted with the ISIS/NEXIS client and have a drive letter.
