Product demo

Demo pokazuje proizvod dok radi. Ruke, površina, rezultat. Nema lika koji ubeđuje, nema scene koja se glumi. Ceo format je jedna tvrdnja pretvorena u dokaz koji se vidi. Radi na publici koja već zna da problem postoji i sada procenjuje da li baš tvoje rešenje radi.

Write concept, script and explanations in the user's language. **Write all generation prompts in English**, because the models perform better and the user pastes them unchanged.

What it earns, honestly

Ovo je format koji AI najlakše pokvari. Demo mora da bude fizički uverljiv. Ako se tečnost ponaša pogrešno, ako se materijal savija kako ne bi trebalo, ili ako proizvod menja oblik u pokretu, gledalac to primeti trenutno i ceo dokaz pada. Zato ovde ide referentna fotografija proizvoda obavezno, ne opis rečima.

Why it persuades

• Vizuelni dokaz zaobilazi raspravu. Gledalac ne procenjuje da li si iskren nego da li mu se sviđa ono što vidi.
• Ruke u kadru daju taktilnost. Mozak simulira dodir i proizvod postaje opipljiv.
• Format ne traži jezik. Isti klip radi na svakom tržištu bez izmene.
• Kratko je i ponovljivo. Jedan proizvod, deset funkcija, deset klipova.

Stage 1 — Interrogate the product

Ask what the user is selling, at what price, to whom, and what the single claim is. Do not proceed on assumptions. If they already gave enough context, answer for them and show it for confirmation rather than asking again.

The governing rule: the concept is derived FROM the product, never applied TO it. Quality test before delivering: would this same concept work with a competitor's product? If yes, rewrite.

Stage 2 — Pick the style variant

Demo prodaje dokazom. Animacija ukida dokaz, jer nacrtano može da radi sve. Ako je proces nemoguće snimiti, to je objašnjivač, ne demo.

If the user does not choose, recommend one and say why in one line.

Stage 3 — Script the beats

Jedna funkcija po klipu. Tri funkcije u jednom demou znače da nijedna nije zapamćena.

Write the actual lines verbatim in the user's language. Do not describe what is said.

Stage 4 — Five hooks against one body

Always deliver five opening variants. When hold rate is fine and hook rate is low, only the first three seconds get regenerated, which is five ads for the price of one production.

Structures that hold for this format:

• Ruka već drži proizvod u prvom frejmu
• Radnja počne pre nego što se vidi šta je
• Prvi kadar je rezultat, pa se vraća na početak
• Nešto se prospe, pa se čisti
• Makro na teksturu pre nego što se vidi ceo proizvod

The hook must be a single visible thing. "Curiosity" is not a hook.

Stage 5 — Production

Order of work, do not deviate

1. Ubaci pravu fotografiju proizvoda kao referencu Ovo je jedini format gde je referenca obavezna. Opis rečima ne drži boju ni oblik.
2. Generiši kadar uzimanja On postavlja površinu, svetlo i ruke.
3. Ostali kadrovi iz iste postavke Ista površina, isto svetlo, ista ruka.
4. Video kratko po kadru Dve do tri sekunde po generaciji. Duži klipovi deformišu proizvod.
5. Sklopi bez naracije Ako treba glas, dodaje se preko u montaži.

Model routing

Shot	Image	Video
Ruke i proizvod	Nano Banana Pro sa referencom	Seedance 2.0, drži težinu i fiziku
Tečnost, prosipanje, pena	Nano Banana Pro	Seedance 2.0 ili Sora 2 za fiziku
Makro detalj	Nano Banana Pro	Kling 2.5
Hypermotion	Nano Banana Pro	Seedance 2.0, kontinuiran pokret

On-camera Serbian goes through Google Omni Flash. Other models carry a foreign accent local audiences detect within half a second. If pronunciation still fails, generate the voice separately and apply lip sync with an audio-driven tool over the finished image rather than accepting a foreign-sounding take.

Locked parameters

Every prompt carries these, explicitly or by clear implication. Changing one means generating a different format.

Prompt skeletons

KADAR, uzimanje (Nano Banana Pro sa referencom)

Two hands picking up [PRODUCT] from [SURFACE], the product exactly matching the reference image in colour, shape and proportion. The surface is real and lived-in with faint marks of use. One soft key light from camera left plus a hard raking light across the surface to reveal texture. Static camera looking down at a slight angle, 50mm, shallow depth of field, clean neutral grade. Natural skin texture on the hands with visible pores. No logos other than the product itself, no readable text, no packaging text of any kind.

**KADAR, makro dokaz** (Nano Banana Pro)

Extreme macro of [THE DETAIL THAT PROVES IT WORKS], filling the frame, [WHAT IS VISIBLY DIFFERENT]. Shallow depth of field, one hard light raking across the surface to reveal texture, plain background falling out of focus. 100mm macro lens, static camera, clean neutral grade. Photographic, not rendered.

**VIDEO, radnja** (Seedance 2.0)

[FIRST FRAME] comes alive. The hands [PERFORM THE ACTION], moving with real weight, [ONE PHYSICAL CONSEQUENCE THAT PROVES THE MATERIAL IS REAL]. The product itself stays completely rigid and unchanged in shape and colour throughout. The camera holds still and does not move. Audio: only the working sounds of the action, no music, no speech. A single uninterrupted take filmed in one breath.

### Two phrases that are not optional

Every video prompt closes with `A single uninterrupted take filmed in one breath`, or the models
insert hidden cuts. Never write `zoom`; write `the camera travels toward`. Never name a phone or
camera, or the model draws one into the shot.

## Worked example — Proizvod: sredstvo za uklanjanje masnoće, 890 din. Dokaz: jedan potez brisanja na masnoj ploči šporeta.

**PRIMER · KADAR** (Nano Banana Pro)

Two hands holding a plain spray bottle above a stainless steel cooker hob covered in a dull film of cooking grease, the bottle exactly matching the reference image in colour, shape and proportion. The hob is real and lived-in with faint scratches and one burnt ring. One soft key light from camera left plus a hard raking light across the steel to reveal the greasy film. Static camera looking down at a slight angle, 50mm, shallow depth of field, clean neutral grade. Natural skin texture on the hands with visible pores. No readable text of any kind.

**PRIMER · VIDEO** (Seedance 2.0)

The frame comes alive. The hands press the trigger once and wipe a single straight path across the greasy steel with a cloth, the grease film lifting cleanly and leaving a bright reflective stripe with a soft ridge of residue pushed up at the edge. The bottle stays completely rigid and unchanged in shape and colour throughout. The camera holds still and does not move. Audio: the spray, the drag of cloth on steel, faint kitchen ambience, no music. A single uninterrupted take filmed in one breath.

Use this to calibrate how much detail belongs in each bracketed slot.

## Failures and repairs

**Proizvod menja oblik u pokretu**
→ Kratke generacije, dve do tri sekunde. I obavezno referentna fotografija.

**Model izmisli natpis na pakovanju**
→ Dodaj `no readable text of any kind` u svaki prompt.

**Tečnost se ponaša pogrešno**
→ Seedance 2.0 ili Sora 2 za fiziku. Kling ovde gubi.

**Nema teksture na površini**
→ Traži `hard raking light across the surface`. Bez kosog svetla nema dokaza.

**Ruke izgledaju plastično**
→ Traži pore i sitne nepravilnosti. Ruke su najteži deo za AI.

**Tri funkcije u jednom klipu**
→ Jedna po klipu. Napravi tri klipa umesto jednog.


**Three-attempt rule.** If the same problem survives two generations, change the approach rather
than the prompt: add a reference image, halve the shot, or split the action into two generations
joined in the edit.

## Assembly

- **Redosled** Uzimanje, radnja, rezultat, makro, poziv. Do 20 sekundi.
- **Rezovi** Na pokretu, ne između. Rez u mirovanju izgleda kao greška.
- **Titlovi** Kratki, samo ključna tvrdnja. Slika nosi dokaz.
- **Zvuk** Zvuk radnje je pola formata. Muzika tiho ili nikako.
- **Serija** Isti proizvod, deset funkcija, deset klipova iz iste postavke.

## Deliver

KONCEPT:      [one paragraph, what happens and why it comes from this product]
VARIJANTA:    [which style, and why]
SCENARIO:     [beat by beat, with verbatim lines]
PET HOOKOVA:  [five openings against the same body]

Then every prompt in English, complete and pasteable, labelled by shot. Then one line on what to
check first in the result.

## Never

- Deliver prompts without a concept behind them.
- Deliver a concept that would survive a product swap.
- Return prompt fragments or advice about what the user should edit. Full prompts only.
- Recommend a style variant this format does not support.
- Let the word "zoom" or a named recording device into a prompt.
- Substitute a model when Serbian speech is on camera.
