Ad Spot, Explainer or Technical Animation: Which 3D Video Belongs at Which Stage of a B2B Sale

First, the basics: what a sales funnel actually is

Before we compare formats, one term needs pinning down, because everything else hangs off it. A sales funnel is a simplified map of the journey a buyer makes — from the moment they have never heard of your company to the moment they send a request for quotation. The name comes from the shape: plenty of people at the top, still looking around; a handful at the bottom, actually buying.

In B2B that journey tends to be long. The decision usually involves several people from different departments, the budget has to be defended in front of a board, and months can pass between first contact and a purchase order. The buyer is looking for information the whole time — and what they find at each stage genuinely affects whether they move on.

Three moments are enough for our purposes, because each one asks a completely different question:

• Top of the funnel — the buyer isn’t looking for anything. They don’t know your brand, and sometimes don’t even realise the problem you solve applies to them. The question here is: what is this?
• Middle of the funnel — the buyer knows they have a problem and is working out who can solve it. Your solution is open in one tab, two competitors in the others. The question here is: how does it work, and how is it different?
• Bottom of the funnel — the buyer has settled on a direction and is now hunting for reasons not to get this wrong, plus material to defend the choice internally. The question here is: will it work in my setup?

Those questions sit far enough apart that no single video answers all three. A film that stops people at a trade show will be too shallow for an engineer checking construction. Run it the other way and a precise cutaway won’t stop anyone scrolling LinkedIn. Hence three formats rather than one.

The ad spot — when the buyer doesn’t know you exist

An ad spot has one job: stop someone who wasn’t looking for your product. Everything else is subordinate to that. Length is counted in seconds, the pace is quick, and the message comes down to a single thing the viewer should walk away with. A spot deliberately doesn’t explain how anything works, because nobody is asking that yet — the question at this stage is closer to what is that, and why should I keep watching.

It earns its keep where you are competing for attention with the rest of the world: paid reach on LinkedIn, the screen on a trade show stand, the header of a website, an email to a list that doesn’t know you yet. The quickest way to ruin a spot is to cram a spec sheet into it. The material then becomes too slow to scroll past and too shallow to analyse — it works at no stage at all.

When 3D does something a camera cannot

In a spot, 3D offers an advantage footage struggles to match: the product can behave in ways physics doesn’t allow. In our work for KAAST a CNC lathe unfolds and turns into a robot — a sequence nobody can shoot, because no such machine exists. The point was never to explain how the machine cuts metal. The point was to make the brand stick in a hall full of competing stands.

The same logic drives consumer product work, where form, material and light carry the message rather than a cutaway — as in the product animation for Genesis.

The explainer — when the buyer is comparing options

An explainer is built to transfer understanding, not to impress. It shows the principle: what happens inside the housing, the order of assembly, where the medium flows, what changes when a function switches on. This is material for someone who already knows they have a problem and is putting your solution next to two others.

It runs longer than a spot — usually a minute to two — because it needs the time to walk through a mechanism. Its natural home is a product page, an attachment to a quote, a slide in a sales meeting, and training for the distributor who will sell your product on your behalf. This is also the stage where 3D starts beating a camera outright: heat transfer, pressure in a circuit and parts moving inside a sealed housing simply cannot be filmed.

In the work for AFL Motors the explainer takes a fan apart and labels every component on screen — the bearings, the mounting console, the EC motors with their power ratings. That same 3D model later fed the advertising animations, the catalogue visuals and the trade show material.

Explanation and advertising in one: the Knauf Therm case

Splitting video into three formats is convenient when you are planning. In practice the boundaries blur. Sometimes a single piece has to look like advertising and explain like an explainer at the same time — because it lands in a channel where nobody stops for a dry cutaway, and the specifics still have to get through.

Knauf Therm is a good example. The problem is typical of building materials: insulation only does its job hidden — inside walls, under floors, beneath the roof. In a finished building you cannot show it without taking a wall apart. What we built was a cross-sectioned model of a house with the layers partly peeled back, and the application point of every product marked directly on the building.

The material works on two levels at once. Visually it is an attractive architectural render that holds its own on social media and on a website. Substantively it is a map of applications a salesperson can walk through point by point. The same set of models later went onto the manufacturer’s site as an interactive presentation, and into catalogues and printed material.

Technical animation — when the buyer needs certainty

A technical animation sits closest to documentation and furthest from advertising. Its job is to take risk out of a decision: it shows construction, layers, materials, cutaways and the details that occupy three pages of tables in a quote. The person watching is usually not the client’s marketing team but a technical lead who has to say „yes, this will work for us” — or block the purchase.

It is the format for products whose value sits inside, out of sight. In the Magnat Mattresses work a 3D cross-section shows the layers in sequence — pocket springs, latex, foam, coir — in a single image instead of a wall of specification text. A buyer has no way to cut a product open in a shop, so until they see this, they are buying blind.

Industry works the same way. For Hexonic we produced cutaways opening up the inside of a heat exchanger, together with an animation of the heat transfer itself — a process no camera will ever record, because it happens inside a sealed housing and is invisible to begin with.

The three formats side by side

The table below is not a ranking. None of these formats is better than the others — each answers a different question, and each loses its point when used at the wrong moment.

The most common briefing mistake: one film for everything

The sentence that opens most project conversations is „we need a video about the product”. It says nothing about who should see it or when — and everything depends on that: length, pace, level of detail, whether we go inside the housing at all. Material built to satisfy everyone usually lands with no one.

The good news is that you don’t have to pick one format and give up the rest. The expensive part of the project is building the 3D model; the shots themselves are considerably cheaper against it. One model, once built, carries the next formats for years.

In the HF Inverter work the starting point was a folder of CAD files. What came out of it was catalogue visuals, trade show material, an explainer and an interactive 360° presentation on the website — a full set covering the whole funnel, ready before a physical prototype existed.

At AFL Motors the same model fed advertising animations, visuals, catalogues, leaflets, an explainer and large-format graphics for a stand. That changes how the budget adds up: a 3D model is not the cost of one advert, it is a component that serves one channel after another — and the cost per piece of material falls with every format you add.

How to pick the format for your situation

Rather than starting with a format, start with four questions. The answers usually point to what should be made first.

1. Who has to see it, and do they already know you? If they don’t — you need a spot. If they know you and are comparing — an explainer. If they know you, have compared, and are hesitating — a technical animation.
2. Where will it play? Trade show material follows different rules from an attachment to a quote. Settle the placement before the script.
3. Is the product’s value visible from the outside? If not, a cutaway will do more than the best-lit packshot.
4. Where are you actually losing buyers? If nobody knows you, a technical film won’t help. If enquiries arrive but never turn into orders, a spot won’t fix that. Start with the stage where something is jamming.

If the answer to any of these isn’t obvious, the usual move is to start with one 3D model and one format, then add the rest once you know where the material is genuinely needed.
