The Format Library

A reference for the repeatable structures behind short-form video. Every entry documents one format: what it is, why it holds attention, the beat-by-beat anatomy you can reuse, and the mistakes that kill it.

Short-form video is not really a medium of ideas, it is a medium of formats. The same structure - a countdown, a narrated confession, a binary choice - gets refilled with new subject matter thousands of times a week, and it keeps working long after any individual trend has died. A creator who understands the structure can produce indefinitely. A creator chasing trends is starting over every week.

This library exists because that structural knowledge is mostly undocumented. It lives in creators' heads and in scattered tutorials about individual trends, and there is no reference that treats formats as a taxonomy. These pages are our attempt at one.

Formats you can build in ViraShort

• Ranking CountdownA ranking countdown is a short-form video that presents five or so items in descending numbered order, using the unresolved question of what places highest to hold a viewer through the middle of the video.
• Commentary ShortA commentary short is a vertical video in which a narration track drives the video and the footage supports it, rather than the other way round.

Reference formats

Documented here because they matter to anyone running a faceless channel. ViraShort does not generate these yet; each page says plainly what the product does and does not do.

• Reddit StoryA Reddit story short is a vertical video in which a narrator reads a first-person post from a confession or judgement subreddit - r/AmItheAsshole, r/TIFU, r/MaliciousCompliance - over unrelated looping background footage, usually mobile gameplay, with the narration burned in as synchronised captions.
• Text Message StoryA text message story is a short-form video that tells a story entirely through a simulated messaging thread - usually iMessage - in which bubbles, typing indicators and read receipts appear one at a time, often with a narration track reading each message, over a looping background such as mobile gameplay.
• POVA POV short is a vertical video that opens with an on-screen caption beginning 'POV:' which assigns the viewer a role or a situation, then plays that scenario out as though the camera is the viewer's own eyes.
• Would You RatherA would you rather short is a vertical video that presents the viewer with a series of two-option dilemmas, one at a time, and forces a choice between them with no third answer available.
• QuizA quiz short is a vertical video that poses a series of trivia questions on screen, gives the viewer a visible countdown of a few seconds to answer each one, then reveals the correct answer before moving to the next question.
• Tier ListA tier list is a short-form video that sorts a set of items into labelled bands - conventionally S, A, B, C and D, with S as the highest - on a grid that stays visible on screen while the creator places each item and defends the controversial placements.
• ListicleA listicle is a short-form video that presents a fixed number of items about one subject in an order that carries no meaning, using an on-screen counter to give the viewer a sense of progress.
• Split ScreenA split screen short is a vertical video divided into two or more stacked panels, where one panel carries the audio and the actual content - a narration, a story, a clip - and the other plays unrelated, muted, rhythmic footage such as mobile gameplay, soap cutting or marble runs whose only job is to occupy the viewer's eye.
• Before & AfterA before and after video is a short-form transformation reveal built on a single cut between two states of the same subject, shot from the same camera position so the viewer can compare the two frames directly.

How to use a format

Pick the format before you pick the topic. This is the inversion most creators never make: they find something interesting and then look for a way to present it, which produces a video with no structural reason for anyone to finish it. Working the other way round - choosing the countdown, then asking what would make a good countdown - produces videos that hold attention because the retention mechanism was decided first.

Then treat the anatomy on each page as a constraint rather than a suggestion. The timings exist because attention decays at a fairly predictable rate on vertical feeds, and formats that violate the beat structure tend to leak viewers at exactly the point where they diverge from it.
