How to show a product modification you have not built yet

Last updated 2026-09-01 · 8 min read

What is the short version?

You have an idea for a modification and no way to show it. A drawing does not convince anyone; a video of it working does — and the whole question is whether the parts in that video look like the parts people can actually buy.

1. Go to Vizard Agent and name the real products by model number.
2. Describe the mounting: where, how high, which side.
3. Say what the rig does as it moves.

What do you need before you start?

Model numbers and a clear description of the geometry. Vizard Agent looks the products up and works from their real photographs, so naming a specific model gets you something recognisable while "a hedge trimmer" gets you a generic one.

• The model numbers. Both products, exactly.
• The mounting. Which end, which side, how high.
• The action. What it does as it moves forward.
• The setting. Where the rig is being used.
• The length. Thirty to sixty seconds.

What do you type into Vizard Agent?

Describe the geometry precisely and let it find the parts. Vizard Agent researches each product itself, so specifying the mounting in measurements rather than adjectives is what determines whether the finished video shows your idea or something adjacent to it.

Prompt

Variants worth knowing:

• Model numbers, always. They get you the real object.
• Heights in numbers. "Six inches", not "low".
• Say which side. Left and right are not interchangeable.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real modification concept video. Nearly half the session goes by before anything is generated at all: it spends that time finding real photographs of both products across several retailers and checking its own generated references against them.

1. Checks the client history and the previous delivery's style.
2. Researches both products and fetches reference images from the web.
3. Pulls product photos from the manufacturers' own pages.
4. Screenshots the product pages from three separate retailers.
5. Views each page and crops the product out of the screenshots.
6. Generates product reference images for both items.
7. Checks the generated references against the real photographs for accuracy.
8. Generates the mounted assembly references — the two parts joined as described.
9. Reviews the assembly sheet and the rig in the field.
10. Generates a first-frame still for each shot and reviews them all together.
11. Animates every shot and generates the audio.
12. Reviews the motion frames and inspects the blade clip closely.
13. Regenerates the weak shots and reviews the retakes frame by frame.
14. Assembles the cut with crossfades, mixes the audio and diagnoses an audio dip.
15. Rebuilds a tighter edit, verifies the levels and reviews the delivered cut.

Step seven is what keeps this honest. Vizard Agent compares its generated product references against the manufacturers' actual photographs, because a video of a modification is worthless if the tool in it is not the tool you told people to buy.

What does the result look like?

The film this page is written from ran to 61 steps and delivered a short product-demonstration cut: the rig assembled as described, the blade at the stated height on the stated side, and the cart moving forward through the crop with the sound to match.

What matters is that both products are recognisable. Someone who owns that trimmer and that cart can look at the video and see their own equipment, which is the only reason a concept video persuades anyone.

When does this not work well?

This shows an idea convincingly, which is precisely the reason it needs handling with care. Vizard Agent generates exactly what you describe to it, and what you describe had better be something that would genuinely work — and be safe — if somebody went and built it.

• It is a concept, not a test. Nothing here proves it is safe.
• Obscure products. Little reference imagery to work from.
• Complex mechanisms. Fine detail drifts between shots.
• Someone else's brand. Say clearly it is unofficial.
• Implied endorsement. The manufacturers have not approved it.

How do you fix a result that came back wrong?

Say what is wrong with the rig itself, or with a particular shot of it. Vizard Agent keeps the verified product references, the mounted assembly sheet and every first-frame still, so a corrected mounting is regenerated from the same parts you already approved.

• "The blade is on the wrong side." Assembly regenerated mirrored.
• "That is not what the cart looks like." Reference re-checked against the real photos.
• "The blade sits too high." Re-generated at the stated height.

How does Vizard Agent compare to doing it yourself?

By hand you either build the thing and film it, or you accept a drawing. Prompting a generator directly gets you a plausible tool that is not the one you named. Vizard Agent grounds the references in real product photography first.

Common questions

Do I need to own the products? No. Vizard Agent works from the manufacturers' published photographs.

Why give model numbers? So the video shows the actual product. Vizard Agent looks each one up specifically.

Will it look like the real thing? That is the point of the reference stage. Vizard Agent checks its images against the real photos.

Can it show the modification working? Yes. Vizard Agent animates the rig performing the action you describe.

How long should it be? Thirty to sixty seconds. Vizard Agent uses a handful of shots rather than many.

Can I use it to sell the idea? Yes, with a clear label. Vizard Agent builds the demonstration; calling it a concept is your job.

What about the manufacturers' brands? They appear because they are the real products. Say plainly that the modification is unofficial.

Can it show several mounting options? Yes. Vizard Agent generates assembly references for each and you pick.

Does it add sound? Yes. Vizard Agent generates effects for the machinery and the material being cut.

What if a shot looks wrong? It regenerates it. Vizard Agent reviews every clip and re-shoots the weak ones.

Is this the same as a product ad? No, and the difference matters. An ad shows something you can buy; this shows something you are proposing, and it should say so.

Can it work for a prototype I designed? Yes. Vizard Agent uses your drawings or photographs as the reference instead of a manufacturer's.

Does it check the finished cut? Yes. Vizard Agent reviews the frames, the audio waveform and the motion quality before delivering, and rebuilds the edit when it finds a problem such as a dip in the sound.

How many shots does it use? A handful. Vizard Agent generates a first-frame still for each one so you can see the whole sequence before any of it is animated.

Can it show the rig from several angles? Yes. Vizard Agent generates the assembly from more than one viewpoint and cuts between them.
