The Transition Is Part of the Story

A transition is easy to think of as punctuation between two scenes.

One image ends, something visually interesting happens, and the next one begins. That can be enough when its only job is to move the viewer somewhere else. But when a film shifts between a person and the technology, science or system behind their experience, the transition can carry part of the explanation itself. It can show why those two worlds belong together.

A recent Caris Detect campaign with Kevin Costner is an interesting example. The film begins in a classroom and then moves through a school corridor where genes and DNA become part of the visual environment before the journey reaches a laboratory. The scientific layer does not arrive as a separate explanatory chapter inserted between human scenes. Instead, the film starts moving towards it while the story is still progressing through a familiar space.

That distinction is important to me because scientific and technological CGI can very easily feel like an insert. We watch a person, stop the story, enter an abstract environment for an explanation, and then return to the person. Sometimes that is exactly the right structure. But when the two layers are meant to explain each other, separating them too cleanly can weaken the idea.

Two worlds should have a relationship

When I directed the launch film for Opera for iOS, the concept was also built around two worlds. One showed the user and the everyday experience of browsing. The other revealed the developers and the technology behind the browser, almost as if we were looking behind the surface of the product while it was being built.

The idea was that the developers were constantly responding to how people use the browser, anticipating what they might need next and improving the product almost in flight. On the other side, the user experienced the result of those decisions in a very simple, everyday way. What interested me was not just the contrast between these spaces, but the relationship between them.

I thought about it almost as a dance. The user and the people building the product are partners, attentive to each other's movements. One side creates a need or a behaviour, the other responds, improves something, and changes what becomes possible next. The transition between those worlds therefore could not feel like a technical break in the film. It had to preserve the sense that both sides were part of the same conversation.

Simply cutting from a person using Opera to an impressive technological environment would have shown the technology, but not necessarily explained its relationship with the user. By allowing one world to lead into the other, the transition became part of the idea rather than an effect placed between two parts of it.

The transition starts before post-production

A convincing transition between two worlds is rarely solved by finding the right effect at the end. Its logic starts much earlier, often while the environments themselves are still only drawings or rough geometry. In a treatment or storyboard, the first questions are already spatial: where are we going, what remains constant, what begins to change, and what should the viewer understand while that change is happening?

Previs makes those questions much more concrete. You can test what the camera continues to follow, whether the perspective survives the move into another environment, how motion carries from one space to the next, or how quickly the image can transform before it begins to feel like a completely separate sequence. Those decisions may sound technical, but they directly affect whether the audience experiences one continuous thought or two disconnected pieces of film.

This becomes particularly important when live action, product storytelling and CGI have to coexist. Scientific CGI is often visually strong enough to command attention on its own, which is exactly why it can accidentally interrupt the story. If the molecular, technological or data-driven layer is meant to reveal something that already exists behind the human experience, the transition has to prepare that relationship before the viewer arrives there.

Something should survive the change

Continuity does not mean that two environments need to look similar. In many cases they should feel radically different. The useful question is what survives as one world becomes the other. It might be camera direction, the position of a subject, a line of movement, a source of light, a shape that changes function, or simply the rhythm of the action.

Those connections allow CGI to inherit something from the scene before it. The new environment can be abstract, microscopic or completely impossible, while still feeling like the next part of the same thought. That is what I find interesting in the Caris Detect example. The classroom, corridor, molecular imagery and laboratory are clearly different spaces, but the viewer keeps moving through the idea rather than stopping to receive a separate science sequence.

The same principle can be useful far beyond scientific visualization. Technology, data, mechanics or any other invisible system often sits behind an experience we can easily photograph. The transition gives us a chance to reveal that hidden layer without abandoning the story that brought us there.

Previs is a storytelling tool

This is one of the reasons I value previs beyond its obvious production benefits. Of course it helps to test camera movement, timing, scale and whether a shot is practically achievable. More importantly, it gives us a cheap and flexible place to ask whether the idea actually reads.

Do I understand why we entered this second world? Does the movement reveal something about the relationship between the two spaces, or are we moving the camera because the shot looks impressive? Does the scene still feel like one story once the visual language changes? These are much easier questions to answer while the world is still simple.

Later in production, environments become detailed, simulations begin to work, materials are refined and lighting starts to make individual shots beautiful. At that point it becomes much harder to question a transition that has already consumed a lot of work. A strong previs gives us the opportunity to solve the narrative relationship before craftsmanship makes us emotionally attached to the image.

For me, the best transitions are not necessarily the ones the viewer notices most. They are the ones that make the next world feel like it was always there, waiting to be revealed.
