Justification file: our method, line by line
A healthcare video rarely gets stuck on the animation: it gets stuck on a line. At EryonStudio, the script is fully referenced before the first frame, and every line keeps its reference, its page and the exact passage that supports it. This is the justification file, delivered with every client film.

The script first, the visuals second
Six rules, applied to every film before the first frame.
![Animation: a frame from our video on varicocele; the camera moves towards the line of sources, the source “[2] CNGOF 2024, p. 13” lights up, a thread links it to the exact passage, highlighted word by word in the document, then the film's figures: 29 referenced lines, 16 references, 59 exact passages](/assets/images/studio/preuve-phrase-source-passage-en-1600-RHV--ae.jpg)
-
Sources first
Guidelines from the HAS, the French National Authority for Health, and from medical societies, institutional reports, literature reviews, the SmPC or the leaflet for a product: the list of sources is fixed before writing begins.
-
One line, one verifiable idea
Every line carries a single idea, precise enough to be checked against a passage. If the source does not say exactly what the line says, we rewrite the line, never the source.
-
The exact passage, with its page
For every line, the passage that supports it is copied word for word, with the page of the document. A translation is marked as such.
-
Caution where the evidence calls for it
A mechanism that is only probable is worded with may or could; the type of data, in humans, in animals or in vitro, is stated when it matters.
-
Distribution rules from the first draft
Information or advertising, general public or professionals: the framework is set at scoping, and the expected statements are written with the script.
-
The visuals follow the text
The storyboard starts from the approved script. On screen, the line of sources accompanies every spoken line, as in our films.
A published video, with all its sources
Our video on varicocele shows its sources during every line. Its page gives the text of the voice-over, in French, line by line, with the on-screen sources and its 16 references.

The justification file, row by row
Five rows from the file of our video on varicocele, in French: the spoken line, the source, the page and the exact passage. A single line can rest on several sources.
| Line from the video | Source | PDF page | Exact passage |

The full file for this video ties its 29 lines to 59 exact passages, cited 64 times.
Who uses it, and how
The same file serves everyone who reviews.
A pharmaceutical company's MLR reviewers check every claim without hunting for the sources themselves.
In France, the company's responsible pharmacist (pharmacien responsable) prepares the ANSM advertising visa application with references already paginated.
The co-authoring doctor reads the quoted passages before approving the medical lines.
A patient organisation shows where each piece of information comes from when a member asks a question.
The marketing team reuses the approved lines in adapted versions, without losing their sources.
Four steps, from source to approval
The four steps of every film, and the justification chain of a real line.
- 01
Scoping, in 30 minutes
Objective, audience, where the video will be shown, available references and regulatory points to watch.
- 02
The referenced script
Every line is tied to a reference, with its page and the exact passage that supports it.
- 03
The visuals
Motion design and medical animation, with AI assisting part of the production. Diagrams remain illustrations.
- 04
Checks and delivery
An automated check finds every passage, word for word, on the page cited; two independent AI-assisted audits then re-check a sample in the documents; your review committee, or your MLR review in a pharmaceutical company, approves the final version.
What you receive
The justification file is part of the deliverables of every client film, with the script and the references.
The film and its broadcast files
Landscape for your website, YouTube and the training room; portrait, square or 4:5 for social media.
Subtitles and transcript
SRT file and full text: accessibility, viewing without sound and search visibility for the page that hosts the film.
The script and the justification file
Every line, its reference, its page and the exact passage, ready for your internal review.
The bibliographic references
The full list, in order of appearance, with links to the public sources.
The versions you need
Short excerpts, stills, a poster or slides, depending on your channels. Quoted with the final version.
Languages
The languages you choose: every translated line keeps its source and exact passage, and the rules of the country where the video is shown are checked at scoping.
What the method does not do
The justification file replaces neither your committee's medical review, nor, for a promotional video shown in France, the ANSM visa, nor the prior authorisation some medical device advertisements require. It does not say that a video is compliant: it shows where each line comes from, so that those who approve it can do so quickly and on the evidence. Today, an automated check finds every passage on its page, then two independent AI-assisted audits re-check a sample; this double audit applies to scripts written since 22 October 2026. No doctor has yet signed off the review of our awareness videos: their publication is decided by an Eryon founder, who is not a doctor. Your films, for their part, are approved by your review committee.
Frequently asked questions
What does a justification file contain?
For every line of the voice-over: the reference or references that support it, the page of the document, the exact passage copied word for word, its translation when the passage is in English and the film in French, and the type of source (guideline, systematic review, information sheet). It is delivered as a spreadsheet, with the script and the list of references.
Is the justification file public?
For a client film, it belongs to you and serves your review. For our awareness videos, it is not published: each video's page shows, line by line, the on-screen sources and the list of references. A source to discuss? Write to contact@eryon.eu.
Who checks the quoted passages?
An automated check finds every passage word for word on the page cited; two AI-assisted audits independent of the writing, one of them by a model from another family, then re-check a sample. Our video on varicocele went through the automated check and one independent audit, on 15 October, on the previous version of the script. For your films, your review committee, or your MLR review in a pharmaceutical company, then approves the script. For our awareness videos, no doctor has yet signed off the review: their publication is decided by an Eryon founder, who is not a doctor.
Is the justification file enough to obtain the ANSM visa in France?
No. It makes the application easier to prepare, because every claim in it is tied to its reference and its page, but the decision lies with the ANSM, and internal approval with your responsible pharmacist (pharmacien responsable) and your MLR review.
Can you reference a script we have already written?
Yes. We start from your texts and your references: every line is tied to its source and its exact passage, and any line that no source supports is flagged to you before production.
