Hi Robin,
The link you posted does indeed get to Quicktime 7 but the registration codes needed to unlock the Pro version is what’s not available from Apple anymore…at least not officially. People are offering their old codes online so I have subsequently been able to get a fully functioning version of Pro 7.
However, what I’ve now discovered is that you can change the metadata within Quicktime 7 Pro but it doesn’t actually translate to the file labels as they would appear in an NLE. That still shows each track labeled identically with the main file name. Presumably, distributors would be opening up the Master file in an NLE to create submasters, etc. so it would be better if each track in the timeline was labeled with it’s correct channel assignment.
Perhaps I’m doing something wrong, but after I’ve changed the metadata for each audio track in Quicktime Pro, everything from FCPX, Resolve, Avid MCP and even ProTools are still not displaying the changed track info.
