Why Video Became the Default Format, and What It Is Bad At

Video became the default communication format for reasons that had little to do with its merits as a medium. Understanding what those reasons actually were is what makes it possible to choose the format deliberately rather than by default, and choosing deliberately is where most of the available value sits.

What Actually Changed

Three infrastructural shifts, none of them about video’s expressive qualities.

Connections. Streaming a moving image reliably to a handheld device required bandwidth that did not previously exist. Once it did, video became viable everywhere rather than only on a desk.

Cameras. Capable cameras in every pocket removed both the equipment barrier and the skill barrier for basic production, which multiplied the amount of video being made by orders of magnitude.

Platform incentives. The services with the largest audiences built their recommendation systems around video, and content that a platform promotes is content that gets made. This is the largest factor and the least often named.

Format adoption follows distribution. Video did not win an argument about effectiveness; it became the thing the infrastructure and the platforms were arranged around.

What Video Is Genuinely Good At

Naming these precisely is more useful than a general claim about engagement.

Showing a process. Anything sequential, physical or spatial — how a thing is assembled, how a technique is performed, how a space is arranged — is communicated faster by watching than by reading. This is the strongest case and the most under-produced category of video in most organisations.

Conveying a person. Manner, credibility, warmth, competence and the sense of knowing who you are dealing with come across in a way text cannot replicate. For professional services and for anything where trust precedes the transaction, this is the substantive advantage.

Demonstrating that something exists and works. A claim in text is a claim; the same thing shown working is evidence.

Reaching people who were not looking. Video in a feed reaches an audience with no prior intent, which text in a feed largely does not. This is a distribution property rather than a communication one, and it is real.

Communicating with an audience that will not read. Not a criticism of the audience — reading a page of text requires a decision that watching does not.

What Video Is Bad At

The honest list, which is rarely written down.

Reference material. Anything a reader needs to consult rather than watch: specifications, instructions to follow while doing something, prices, comparisons, procedures. Video is linear, and returning to a precise point in a linear medium is slow.

Scanning. A reader skims a page and finds the relevant paragraph in seconds. A viewer cannot skim a video, and chapter markers are a partial remedy rather than a solution.

Searching and copying. Text is searchable, quotable and extractable. Video’s contents are effectively invisible unless a transcript exists.

Comparison. Two written specifications sit side by side. Two videos cannot be compared without watching both in sequence and holding one in memory.

Dense information. A page of text carries more information than a minute of speech, and speech cannot be re-read at the point where attention lapsed.

Speed of production and correction. A written page is made in an afternoon and corrected in a minute. A video takes days and a correction means a re-edit or a re-shoot.

The Choice That Should Be Made Deliberately

The most common waste in content production is a video made because video was assumed.

A useful test is to ask what the audience will do with the information. If they will watch it once to understand something, video is a candidate. If they will consult it, follow it while doing something else, compare it, or return to one part of it, text is better and cheaper.

The second test is whether motion or a person carries the substance. If the answer is neither — if the content is a list, a set of facts, a comparison or a procedure — the video version is a slower delivery of the same material.

Many subjects deserve both, and the efficient arrangement is a written page as the reference plus a short video for the part that benefits from being shown. That is a decision about which parts of the information each format handles rather than a duplication.

The Saturation Argument

The volume of video now being produced is frequently cited as a reason to produce more of it. The opposite conclusion follows at least as easily.

A saturated format means every piece competes harder for a fixed amount of attention, and the pieces that succeed are the specific and genuinely useful ones rather than the ones that exist. An organisation choosing between producing twelve unremarkable videos and three that answer questions its customers actually ask is not facing a close decision.

What Cannot Be Claimed Here

Statistics about video’s effectiveness circulate widely, are frequently produced by organisations selling video, and date immediately. This reference publishes none of them, because a figure whose methodology cannot be examined is not evidence.

What is verifiable instead is local and specific: an organisation’s own analytics on its own material, showing what people actually watched and where they stopped; its own support and sales questions, which indicate what content is missing; and the published specifications of the platforms it uses, which state what each format technically requires.
