The Ontology of the Short-Form Frame: Defining the Disciplinary Scope

The endeavor to define short-form video is itself an exercise in compression. To encapsulate a medium that has simultaneously reconfigured global attention economies, democratized cinematic production, and spawned novel semiotic systems within a single definitional statement is to confront the very challenge that characterizes the medium: the necessity of achieving maximal signification with minimal means. Conventional approaches—anchored in duration thresholds, platform taxonomies, or distribution mechanics—prove inadequate, not merely because they fail to capture the medium’s heterogeneity, but because they mistake contingent attributes for essential qualities. This chapter argues that short-form video constitutes a distinct ontological category precisely *because* it operates under a unique constellation of perceptual, cognitive, and economic pressures that demand a specialized cinematic language. We propose a shift from defining the short by its brevity to understanding it through the lens of *compressed complexity*—a condition wherein narrative, aesthetic, and informational density are deliberately intensified to overcome the medium’s inherent constraints. This foundational reorientation allows us to move beyond platitudes about “short attention spans” and toward a rigorous framework for analyzing how meaning is constructed under conditions of extreme resource scarcity, where the primary scarce resource is not time, but *attention capital*.

The Insufficiency of Conventional Definitional Axes

Duration as a Proxy for Essence

The most immediate and pervasive attempt to define short-form video relies on temporal boundaries. Industry reports, academic studies, and platform documentation frequently invoke thresholds: videos under 60 seconds, under 90 seconds, or even more narrowly, under 15 or 30 seconds. TikTok’s original limit of 15 seconds, later expanded to 10 minutes, has become a cultural reference point, while Instagram Reels and YouTube Shorts typically cap at 60 and 90 seconds, respectively. These boundaries are not arbitrary in a practical sense—they are engineered constraints designed to optimize mobile viewing and infinite scroll behaviors—but they are ontologically insufficient. A 59-second lecture on quantum mechanics and a 59-second clip of a cat falling off a couch share a duration but belong to entirely different communicative universes. The temporal metric confuses a *container* with its *content*; it describes a boundary condition but not an internal logic.

Moreover, the historical elasticity of “short” reveals its contingency. The “short film” category in festivals often accommodates works up to 40 minutes, a duration that would be interminable on a For You Page. The very notion of “short” is relational, defined against a presumed norm of “long-form” content. But what constitutes long-form is itself in flux: the feature film standard of 90-120 minutes is a 20th-century industrial construct, while a 10-minute YouTube video is now considered “long” in many algorithmic contexts. Duration, therefore, is a variable parameter within a dynamic ecosystem, not a fixed essence. Relying on it as a primary definer leads to a category error, grouping together works based on a superficial commonality while obscuring profound differences in structure, purpose, and reception. It is akin to defining all novels as “books with more than 50,000 words”—a useful library-sorting heuristic but a barren ground for literary theory.

Platform Constraints as Deterministic Boundaries

A second common axis of definition is the platform itself: short-form video *is* TikTok, or Reels, or Shorts. This identification is understandable, as these platforms have been the primary vectors for the medium’s global diffusion and have established the dominant design patterns. However, it conflates a *distribution channel* with a *medium*. The platform provides the technical infrastructure (vertical 9:16 aspect ratio, full-screen immersion, native editing tools, algorithmic feed) and the social context (duets, stitches, sounds, challenges), but these are enabling environments, not the medium’s core ontology. To claim that short-form video is defined by TikTok is to ignore that identical formal strategies—rapid cuts, on-screen text, synchronized audio trends—migrate across platforms, appear in advertising, and infiltrate long-form content. The platform is a host, but the virus of compressed complexity can jump between hosts.

Furthermore, this definitional stance renders the medium hostage to corporate strategy and market competition. Should TikTok vanish tomorrow, would the cinematic language it cultivated disappear? Unlikely. Its formal innovations would be absorbed, adapted, and recombined within whatever environment succeeded it, as has happened repeatedly in media history (e.g., the migration of music video aesthetics from MTV to YouTube). The platform shapes the *expression* but does not determine the *essence*. A more robust approach examines the *affordances* common across platforms—the mobile-first, single-handed, scroll-based interaction model—rather than the proprietary features of any single app.

Distribution Mechanics as Constitutive Features

A third approach focuses on distribution: short-form video is defined by its algorithmic curation, infinite scroll feed, and performance-based virality. This perspective highlights the medium’s entanglement with platform capitalism and attention markets. The “For You Page” is not merely a delivery mechanism; it is an active agent that shapes creation through its reward signals. Creators optimize for watch time, completion rate, and shares—metrics that directly feed back into production decisions. Thus, distribution appears constitutive: the form is shaped by the logic of the feed.

However, this view risks a form of technological determinism. It posits that the algorithm *creates* the form, rather than recognizing a co-evolutionary relationship. The algorithm rewards certain patterns because they align with human perceptual and cognitive biases (e.g., motion detection, novelty seeking, pattern completion), which existed long before TikTok. The compressed complexity we observe is a solution to a universal problem—how to capture attention and convey meaning efficiently—that finds its most extreme and data-driven expression in the algorithmic feed. Distribution mechanics are a powerful *selective pressure*, but they operate on a pre-existing repertoire of cinematic techniques and human psychobiology. To define the medium solely by its distribution is to confuse the ecosystem with the organism.

Toward an Ontology of Compressed Complexity

If duration, platform, and distribution are inadequate as essential definitions, what remains? We propose that the defining characteristic of short-form video is not its length, but its *operational condition*: it must achieve its communicative or affective goal under conditions of extreme attention scarcity, high scroll velocity, and platform-native grammatical expectations. This condition forces a unique formal response: compressed complexity.

Defining Compressed Complexity

*Compressed complexity* refers to the deliberate intensification of narrative, aesthetic, and informational elements within a minimal temporal and spatial frame. It is not “simple” or “simplistic”; rather, it is *densely packed* with meaning, requiring the viewer to engage in active pattern-recognition and inference-making at an accelerated pace. A 30-second short may contain the narrative arc of a traditional three-act structure (setup, confrontation, resolution), but each act is suggested through a single shot, a caption, or a soundbite. The complexity is compressed, not removed. This model stands in direct opposition to the common critique that short-form content is intellectually vacuous, a “dumbing down” of culture. Instead, it represents a *transcoding* of cultural forms into a ne
