How to check an archive photo is really of the event you are naming

Last updated 2026-09-15 · 8 min read

Ask Vizard Agent to check each archive item's licence and its caption, not just what it looks like. It confirms the photograph is of the event you are naming rather than a similar one, checks a location clip really shows the place you claim, and rejects period footage with modern clutter in it.

What is the short version?

A picture that looks right is not evidence that it is right. Archives are full of photographs of other earthquakes, other riots and other years, and a caption beneath one of them turns a plausible image into a false claim.

Tell Vizard Agent what each shot is being used to claim.
Ask for the licence and the caption on every item.
Ask it to check period and place, not just subject.

What do you need before you start?

The script and a clear sense of what each shot is asserting. Vizard Agent checks material against a specific claim, so a brief like "a street in Caracas in the 1980s" is something it can go and verify, while "something that feels like Latin America" is not a claim at all and cannot be checked.

The script. What is said over each shot.
The claim per shot. Place, period, event.
How strict you need to be. Documentary or illustrative.
Where it will be published. It affects the licence needed.
Any material you already have. Rights already cleared.

What do you type into Vizard Agent?

Tell Vizard Agent what each shot has to prove. The test it applies is not whether the picture looks like the thing you mean — it is whether the picture can honestly carry the sentence that will be spoken over the top of it.

Prompt

This is a documentary, so every still and clip has to be what we say it is. For each one, check the licence allows use and read the caption to confirm it is actually this event. For the location shots, check the clip really shows that country. And do not use period footage with modern tourists or signage in it.

Variants worth knowing:

"Check the licence allows use." Separate from whether it fits.
"Read the caption to confirm." The picture cannot confirm itself.
"Not period footage with modern tourists." The commonest failure.

What does Vizard Agent actually do?

Here is the Vizard Agent sequence on a real documentary built from archive stills and location footage. Notice that the checking happens item by item and by name: a general question like "are these all right" only ever produces a correspondingly general answer.

Finds photographs published with the original reporting.
Searches free-photo archives for verified images of the same event.
Reads each item's licence and its caption.
Downloads the real photographs and tiles them into one sheet.
Finds public-domain historical images for the period sections.
Reviews the whole b-roll sheet for accuracy, not for looks.
Reviews the historical stills for use and rights.
Checks a location clip for tourist clutter and rejects it.
Checks a city clip really is the country it is being used for.
Checks a school clip before it is used for a particular country.

Step three is the one people assume is automatic. A licence and a caption are separate facts — an image can be perfectly free to use and be of a different event entirely, and it will pass any check that only looks at rights.

Step eight is a period test rather than a subject test. A clip of the Roman Forum is genuinely the Roman Forum and still cannot run under a sentence about antiquity, because it is full of people in shorts holding phones.

Step nine matters because cities look alike. A generic skyline standing in for a named country is the sort of thing a viewer from that country spots in one second and nobody else notices at all.

What does the result look like?

A cut where every shot can survive the question "how do you know". Vizard Agent tells you what each item is, where it came from and under what licence, so a challenge is answered with a source rather than with an impression.

When does this not work well?

Some claims cannot be sourced. Events before photography, private moments, and anything where the archive is thin will not yield a verified image, and the honest options are a reconstruction clearly labelled as one or a different shot.

Events with no photographic record. Nothing to verify.
Thin or contested archives. Sources disagree.
Images with no caption. Unverifiable whatever they show.
Rights that depend on use. Editorial-only material.
Recent events. Material may be unlicensed or unconfirmed.

How do you fix a result that came back wrong?

Say which of the claims the shot fails. "That is not Caracas" and "the licence does not cover commercial use" send Vizard Agent to two completely different checks, and it can go and replace the item on either ground once it knows which one you mean.

"That is not the right country." The identity is re-checked and replaced.
"There are tourists in it." A cleaner period shot is found.
"The licence is wrong for us." Re-searched under the right terms.
"The caption does not say that." The claim or the shot changes.

How does Vizard Agent compare to doing it yourself?

By hand you search, find something that looks right, and use it — because checking the caption means opening the archive record, and checking the licence means reading terms, and there are forty shots. The one you did not check is the one that gets quoted back at you.

	By hand	Vizard Agent

Common questions

Is public domain always safe? Usually for use, but it says nothing about whether the image is the right event.

Can it read the caption from the archive? Yes. Vizard Agent checks the record rather than the thumbnail.

What if two archives disagree? Vizard Agent flags the disagreement rather than choosing one silently.

Does it check every shot? Yes, if you ask for it item by item. A general check gives a general answer.

What is tourist clutter? Modern people and signage in a period shot. Vizard Agent treats it as a fail.

Can it verify a city is the right one? It checks for identifying features and says when it cannot confirm.

What about editorial-only licences? Tell Vizard Agent where it is publishing and it filters accordingly.

Will it tell me the source? Yes. Ask Vizard Agent for the source and licence of every item used.

What if nothing verifiable exists? Vizard Agent says so, and a labelled reconstruction is the honest alternative.

Can it use my own cleared material? Yes. Tell Vizard Agent what is already cleared and it prefers those.

Does this slow things down? It adds a checking pass, which is considerably cheaper than a correction.

What about generated images? Those are not evidence. Vizard Agent will not use one as archive material.

Can it caption the source on screen? Yes. Ask Vizard Agent for a credit line on each archive shot.

How do I know it actually checked? Ask for the list. Vizard Agent reports the licence and caption it read.
