Real World article
(written from a Production point of view)

This category contains articles related to the release of Star Trek on various home media video formats.

Note to MA editors: It has been observed that video home media entertainment formats have different run times for releases that are produced for those regions employing the NTSC television format (typically North-America, Central-America, and Japan for example), and those that employ the PAL/SECAM television formats, (typically Europe, Southern-Asia, South-America, Oceania, and Africa). This is related to the different frame rate in which the source production is transferred onto its respective format – to wit 24 frames per second (fps, and the motion picture and television standard in which productions are filmed) vs. 25 fps respectively – and translates itself in practice to an approximately 4% shorter run time of the PAL/SECAM formats due to their higher fps rate, especially the VHS, Betamax, LaserDisc, DVD, and early generations of Blu-ray formats, and might lead uninitiated editors to erroneously conclude that scenes are omitted or curtailed, which is not the case.
When referring to a specific time-frame in a production, MA editors are therefore advised to indicate whether it concerns a NTSC production, or a PAL/SECAM production as a courtesy to other MA users.
It appears that this phenomenon no longer applies to the newer generations of Blu-ray releases – and their counterpart digital download formats for that matter – as the sharply increased picture quality with the advent of High Definition (television) has made the 25 fps format increasingly redundant. The newer generation Blu-ray releases adhere to the standard 24 fps format, regardless of which television format a territory employs. In the case of Star Trek, the synchronization appeared to have come into being around mid-2009, as the Star Trek III: The Search for Spock Blu-ray still featured the different run times, whereas the next release in the same year, Star Trek IV: The Voyage Home, was synchronized. For a more detailed treatise on the phenomenon, please refer to PAL's 4% Speedup.
