File:Black Alert sequence from Star Trek Discovery S02E02.webm

{{Non-free use rationale 2

|Description = A 21-second video clip from Star Trek: Discovery season 2, episode 2, depicting a full "Black Alert" spore jump sequence aboard the USS Discovery. The scene includes the black alert lighting cue transition, spore drive initiation by Stamets, mycelial spore cloud animation, and the ship's interdimensional jump and arrival. It also highlights discussed production design features such as the height-differentiated bridge layout, practical OLED-style screens, and the rotating saucer and ring mechanisms. These visuals incorporate unused concepts by Ralph McQuarrie from the unproduced film Planet of the Titans and are used in the Spore drive#Design and production section to illustrate the sequence’s relevance to the show's visual and conceptual evolution.

|Source = Excerpt taken by editor from legally owned Blu-ray copy of Star Trek: Discovery season 2, episode 2, distributed by CBS Studios / Paramount Global.

|Date = 2019

|Author = CBS Studios / Paramount Global

|Article = Spore drive

|Purpose = This video illustrates the unique visual effects and production design of the "Black Alert" spore jump as it appears in Star Trek: Discovery season 2, episode 2. It supports the article’s "Design and production" section, which discusses how the sequence was created using unused visual concepts by Ralph McQuarrie originally developed for the unproduced film Star Trek: Planet of the Titans. The clip shows lighting cues, set transitions, spore cloud animation, and the interdimensional jump, all of which are discussed in the article text.

|Replaceability = No freely licensed equivalent can accurately represent this canonical sequence from Star Trek: Discovery. A recreation, static image, or summary cannot reproduce the visual elements—such as spore cloud effects, lighting cues, and transition design—being analyzed and discussed in the article.

|Replaceability_text = The clip contains complex visual transitions and effects that cannot be described adequately through text alone. The animation of the spores, changes in lighting, and timing of the jump sequence are essential to understanding how the spore drive is presented onscreen and why it differs from traditional science fiction warp effects. A still image or written summary cannot convey the dynamic, layered design that the video captures.

|Minimality = This file uses only a single 21-second excerpt from a full-length episode to illustrate one specific, discussed design element. It does not include dialogue, narrative context, or unrelated scenes. It will only be used in the "Spore drive" article, in the "Design and production" section, to support cited commentary about the drive’s visual presentation. The resolution is limited to 1080p and the file size is compressed for minimal impact. No additional clips from the episode are used elsewhere in the article.

|Commercial = This file is a short, low-resolution excerpt from a much longer copyrighted episode. It does not include full plot content or substitute for commercial access. Its use for educational and encyclopedic commentary in one article does not interfere with CBS Studios / Paramount Global’s ability to profit from licensed distribution.

|Other information = This file satisfies all 10 criteria for non-free content use on English Wikipedia. It is used to support critical commentary in the "Spore drive" article, specifically the "Design and production" section, where this precise sequence is discussed. The video is a 21-second, low-resolution, dialogue-free excerpt limited to one article. It is necessary to illustrate the canonical visual effect of the spore jump sequence, including the implementation of Ralph McQuarrie's legacy design work. No free alternative could capture the specific animation, lighting transitions, and set effects depicted here. This use is transformative, educational, and minimal as required under WP:NFCC, WP:NONFREE, and Wikipedia policy on non-free visual content.
