Post production for advertising spots: the phase that decides everything

April 2026

When an art director talks about a spot, they almost always talk about the shoot. The location, the crew, the cast, the day on set. Post production gets mentioned almost as a footnote — "we'll deal with that later."

After twenty years working on institutional spots, advertising campaigns and product videos, I can say this is the most common and most expensive inversion of priorities in the industry. Post production is not the phase where you fix what was shot. It is the phase where you decide what the spot actually becomes.

The set produces material. Post production produces the video.

This distinction seems obvious but it is not. On set you capture images — good ones, often excellent ones. But those images do not yet have rhythm, do not have chromatic coherence, do not have the emotional breathing that makes a thirty-second spot work. All of that is born in post.

The edit decides the narrative rhythm — where to accelerate, where to breathe, which shot takes the viewer exactly where you want them. The color grade decides the emotional tone — whether the story is warm or cold, whether the product looks luxurious or accessible, whether the brand communicates authority or closeness. The VFX and motion graphics decide what is possible to show — what cannot be filmed, what would cost ten times more on set, what exists only in the creative's head.

An experienced director of photography knows this: the set is half the work. The other half is what happens after.

The case where the set does not exist

The most extreme example of this principle is a project where the set did not exist at all. For the project PMI — Abbiamo Cura di Te, an institutional video for a ministerial campaign, there was no set. No shooting, no crew, no location. The client brief was one sentence: tell an emotional story about a life cycle, with the vague image of a tree from which fruit falls.

Ten days to transform that sentence into a visual concept, a narrative and a graphic style. Seven days to realize the video in motion graphics using the continuous line technique — a flow of animated drawing that passes through every scene without interruption, where the main challenge was not technical but compositional: finding the connections between scenes so that every transition was as beautiful as the scene itself.

The result is a video that does not have a single frame shot on camera. It exists entirely in post production. It is also the project that most clearly shows what it means to have post production at the center of the creative process, not at the end of it.

The phases nobody explains in the quote

When an agency receives a post production quote, they typically see three line items: editing, color grading, sound design. This list is correct but incomplete — and the missing part is often what determines the final result.

Conforming. Before creative editing, the shot material must be organized, synchronized and prepared for work. On a single shooting day with two cameras and separate audio, conforming can require four or five hours of invisible work that never appears in the quote but that, if missing, would make editing impossible.

VFX supervision in pre-production. Every visual effect that will be added in post must be planned before the shoot — camera angles, set lighting, tracking markers. When this supervision is absent, the VFX artist works on material that was not shot with post production in mind, and costs triple.

The color roundtrip. In projects involving an external colorist — like the work on Along Came Ruby, where I collaborated with Walter Volpatto via DaVinci Cloud — the material must be prepared for output, sent, received and reintegrated into the editing project. This technical management is not creative but it is indispensable, and requires specific competence in codecs, color spaces and delivery workflows.

Multi-format delivery. A finished spot is not a file. It is a family of files — TV version in 16:9, social version in 9:16 and 1:1, open subtitles version, closed subtitles version, no-audio version for autoplay, audio version for pre-roll. On a mid-level media campaign, delivery can require fifteen or twenty different versions of the same spot. If this was not planned before editing, each version requires additional work.

Where the costs nobody tells you are hidden

The post production costs that appear in quotes are the predictable ones. The ones that blow up budgets are the costs nobody plans for because nobody discussed them beforehand.

Unstructured revisions. The most common revision system in agencies is still email with attached screenshots and comments like "this color is not right" or "this edit feels slow." Every revision cycle managed this way produces a new round of work instead of converging on the final result. On a project with three unstructured revision cycles, the actual working time can double compared to the quote.

Brief changes in post production. The brief changes during production — it always does. But when the brief changes after the edit is already approved, or after color grading is complete, the cost of that change is exponential. Every modification upstream invalidates the work done downstream.

Missing material. The footage does not cover the editing needs. Inserts are missing, a reaction is missing, the cutaway that allows a rhythm change at a specific point is missing. In these cases you proceed with what you have — and the result shows it.

The solution to all three of these problems is the same: have the post production professional in the creative process from the beginning, not called in after the set has been struck.

What changes with AI — and what does not

AI has changed specific phases of spot post production. It has done so in a real way, not a theoretical one.

For certain environmental elements — skies, backgrounds, set extensions — AI generation produces broadcast-quality material in a fraction of the time that traditional compositing would require. For visual prototyping in pre-production, I can show a director or art director how an effect will look before a single frame is shot. For creative variants — the same spot with three different emotional tones — the AI workflow significantly accelerates the exploration phase.

What does not change: judgment. Knowing which variant works and why. Knowing when AI output is usable and when it is not. Knowing how to integrate generated material with filmed material so the boundary does not show. This is not a technical problem. It is a problem of eye and experience — and it accumulates over years, not weeks.

The Roche Jingle AI project is an example of this balance: a broadcast-quality video made entirely with AI generative tools, but where every generated clip passed through a traditional post production workflow — color correction, stabilization, compositing, grading. The model generated the material. Post production transformed it into a deliverable product.

How to evaluate a post production professional before engaging them

The right question is not "how much does post production cost?" The right question is "does the person doing post production understand this project before I even explain the brief?"

A senior post production professional, looking at a spot or reading a brief, should be able to identify the critical points before they become problems. They should ask about the VFX supervision plan, not just the number of effects. They should ask about the revision system, not just the deadline. They should ask about delivery formats before editing, not after.

If they do not ask these questions, they will probably answer them with an extra charge at the end of the project.

The advantage of working with an integrated workflow — where VFX, editing, color and motion graphics are managed by the same professional — is that these questions do not get lost in handoffs between different specialists. The hidden cost of fragmentation is not only economic. It is one of creative coherence: every handoff introduces an interpretation, and three different interpretations of the same brief produce a result that resembles nobody's brief.

If you are working on a project with complex post production — VFX, motion graphics, color, or simply many versions to deliver — tell me what you need. The best way to understand if I can help you is to talk before the set is already booked.
