Decide whether the pictures are actually the same release
Plex’s version guide distinguishes the same film encoded at different resolutions or with different codecs from genuinely different cuts. A smaller H.264 copy and a larger HEVC copy of one theatrical release are versions. A director’s cut and the theatrical release are editions. Those differences determine whether automatic playback selection is a sensible default or risks choosing a different creative release.
Do not rely on a filename suffix becoming menu text
The guide permits arbitrary descriptive text in filenames for your own file organisation, but says that text is not displayed by Plex. Apps that expose Play Version can instead show technical characteristics. Some apps do not offer manual version selection at all. A suffix saying Director Cut therefore does not prove that every television user will see an intelligible choice before playback.
Plan the library around the viewing decision
For legally held personal media, organise distinct cuts as editions if that is the distinction viewers need. Keep alternative quality encodes under the appropriate edition rather than merging different cuts simply because their title matches. Before changing an established library, note its current metadata and watched state and consult the edition instructions for the intended change. This article does not modify files or supply films. Its purpose is to explain why a technically correct resolution menu can still be the wrong interface for selecting an artistic cut.
