How to show a product's dimensions and fittings on video

Last updated 2026-08-30 · 7 min read

What is the short version?

Most product videos sell a feeling. A listing video has a duller and more useful job: showing how long the thing is, where the screws go and what it looks like once it is on the wall — because those are the questions that stop people buying.

1. Go to Vizard Agent and upload the product and installation clips.
2. List the details that have to be shown — length, fixings, mounted.
3. Say which detail should open the video.

What do you need before you start?

Clips that actually contain the details in question. Vizard Agent finds those moments inside your existing footage, so nothing needs re-shooting provided it is in there somewhere, but a measurement that was never filmed at all cannot be shown.

• The clips. Product, detail and installation.
• The details. The specific facts to demonstrate.
• The measurement. Filmed against something, ideally.
• The order. Which question matters most.
• The length. Fifteen to thirty seconds.

What do you type into Vizard Agent?

List the details as facts rather than as shots. Vizard Agent searches the footage for the moments that demonstrate each one, so "show the 40cm length" and "show the three mounting holes" tell it what to look for far better than a shot list would.

Prompt

Variants worth knowing:

• The product as the opening. Rather than a lifestyle shot.
• A measurement held. Long enough to read.
• Installed and in use. The two states buyers picture.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real product video built from ten clips. The unglamorous step that saves the edit is the fourth: checking each clip's rotation, because phone footage of a product on a bench is frequently recorded sideways.

1. Downloads the footage and checks the metadata of every clip.
2. Extracts frames from each clip to see what is in it.
3. Reviews a preview of all the clips together.
4. Checks the orientation and rotation of every clip.
5. Builds vertical preview contact sheets for all of them.
6. Reviews clips one to five, then six to ten.
7. Checks the audio levels across the source clips.
8. Analyses the last clip and extracts detailed frames second by second for each one.
9. Combines the contact sheets for review, reads them in three batches, then loads the product-ad guidance and builds the sequence.

Step 8 is what finds the details. A measurement is visible for perhaps two seconds in a two-minute clip, and per-second frames are how that moment gets located rather than stumbled upon.

What does the result look like?

From the run this page is written from, probed on the delivered file: 478x850, H.264, 30fps, 16.33 seconds, AAC audio. Vertical, sixteen seconds, opening on the product itself, then the length shown against a measure, then the fixing holes, then the finished installation.

Every second answers a question. That is what makes a listing video different from an advertisement — nothing in it is atmosphere, because the viewer is deciding whether the thing will fit.

When does this not work well?

A video that demonstrates facts can only ever demonstrate what was actually filmed, and product footage is usually shot without this particular purpose in mind. These are the gaps Vizard Agent reports back to you rather than papering over them with a caption.

• Unfilmed details cannot be shown. No measurement shot, no measurement.
• A number on screen is not a demonstration. Buyers want to see it against something.
• Sideways clips need catching early. Rotation metadata is often wrong.
• Short videos hold few facts. Four details is about the limit at twenty seconds.
• Your claims are yours. A stated dimension had better be right.

How do you fix a result that came back wrong?

Name the detail that came out wrong and what should be there. Vizard Agent keeps all the per-second frames, the contact sheets and the rotation checks, so a moment can be swapped or held longer without re-reading every clip.

• "The length goes past too fast." Held longer from the same frames.
• "That clip is sideways." Corrected from the rotation check.
• "Show the fixings before the length." Re-ordered from the located moments.

How does Vizard Agent compare to doing it yourself?

By hand this means scrubbing through ten separate clips hunting for the two seconds where the tape measure is actually readable, and then discovering that three of them import sideways because the phone happened to record them that way.

Common questions

What details are worth showing? The ones buyers ask about. Vizard Agent shows size, fixings, the installation and the item in use.

Do I need a tape measure in shot? It helps enormously. Vizard Agent finds a number on screen persuades less than a measurement.

What if a clip is sideways? Vizard Agent checks the rotation metadata of every clip before it builds anything.

How many details fit? Around four in twenty seconds. Vizard Agent finds more than that and none of them lands.

Should the product open the video? For a listing video, yes. The viewer already knows what they are looking for.

Why extract frames every second? Because the moment that shows a measurement lasts a second or two inside a much longer clip, and sampling more coarsely walks straight past it.

Can it add the numbers on screen? Yes. Vizard Agent places them alongside the demonstration rather than instead of it.

Does this work for furniture and fittings? Especially well. Vizard Agent suits anything where the buyer is asking whether it will fit.

Can I get a longer version? Yes. Vizard Agent builds a longer one with more details from the same located moments.

Should the video have narration? Rarely. Vizard Agent lets the demonstration carry it, because a viewer checking whether something fits is reading the screen rather than listening to a description of it.

What should I film next time? The measurement against a rule, the fixings close up, and the item both installed and in use. Vizard Agent can only find what the camera captured, and those four shots answer most of the questions buyers ask.

Can one set of clips serve several listings? Often yes. Vizard Agent keeps the located moments, so a variant listing for the same product reuses the measurement and fixing shots without any of the searching being repeated.

Is this better than photographs with text on them? For anything about fit, yes. A photograph asserts the dimension; a video shows it being measured, and that is the difference between a claim and evidence.

Does Vizard Agent check the result? Yes. It reviews the located details and the sequence before delivery.
