Is AI video really cheaper than CGI? Compare the approved deliverable

DELA clients ask whether AI can lower production costs. Here is a practical way to compare the complete job, including revisions and usable outputs.

Some clients ask DELA whether AI could make a proposed film more cheaply. This is an observation from our enquiries, not a market survey. The question is reasonable: if a tool can produce a compelling image quickly, it changes what people expect production to cost.

The answer depends on what the client is buying. A promising generated clip and an approved campaign deliverable are different stages of work. Compare the latter before deciding which route offers better value.

Start with an identical delivery brief

Specify duration, shot count, product accuracy, aspect ratios, language versions and the likely approval process. Ask each supplier to quote against that same list. Otherwise one estimate may cover an exploratory clip while another includes a complete film and several rounds of revision.

For an illustrative product launch, agree whether the label must be readable in close-up and whether three colour variants must share the same camera move. Those requirements can affect the production method more than the headline duration.

Count the work between generation and approval

A useful estimate includes preparation, generation or rendering, selection, repair, editing, sound, review and final exports. Record costs in the units the team can verify: paid tool usage, working time and external services. Do not assume that every generated second becomes a usable second.

AI may offer a strong advantage when the concept permits variation and a usable result arrives quickly. A controlled CGI scene may be more efficient when repeated exact changes are expected. Neither conclusion can be established from a subscription price alone.

Test one realistic revision

Ask for a change the client is likely to request. Keep the camera and product fixed, but alter the background. Or update one label while preserving motion and lighting. Measure the work required to complete that revision without disturbing approved elements.

This exposes a difference that a first-pass comparison can miss. In a CGI workflow, defined scene elements and compositing passes can support targeted changes; Blender documents how rendering information can be separated into passes. The actual benefit depends on how the scene and handover were prepared.

Compare cost per accepted output

For a small pilot, divide the total recorded production cost by the number of outputs accepted against the agreed brief. Keep exploratory work visible in the total. If nothing is accepted, report that outcome rather than inventing a favourable cost per deliverable.

Also record elapsed time and revision time separately. A workflow can use little paid compute while consuming substantial review time. Another can require more preparation but make the next approved variation easier. The relevant measure is the one connected to the campaign’s needs.

CGI has to explain its value clearly

Our editorial view is that the ability to produce an attractive image is becoming a less complete explanation of a CGI fee. A stronger proposal explains what the client can control, change and reuse: approved geometry, product variants, animation, editable scenes and a dependable revision process. Those deliverables must actually be included in the agreement.

If a simpler AI workflow satisfies the same requirements more economically, it deserves consideration. If it cannot preserve a critical detail, the cheaper first image is not yet a cheaper film. A short, representative test is a more useful answer than defending one technique in every situation.
