AI Health Video Generator

Science 3D, the default here, renders every scene as a microscopic medical image: translucent cells, organs, blood vessels and viruses on dark backgrounds. It suits how-the-body-works videos, where the subject is something no camera can film: a kidney filtering blood, an immune cell meeting a virus, a nerve signal crossing the brain. A video in it typically costs about 25 credits. The renders are illustrations, not medical imaging, so the accuracy has to come from the script.

Flat Vector builds each scene from clean geometric shapes, the modern science-explainer look. It suits what a condition is, explained for a general audience without graphic detail: what happens during a migraine, or how blood pushes against the walls of the arteries. An antibody becomes a simple Y shape and an artery a tube, which keeps each scene about one idea. About 25 credits.

Whiteboard draws marker doodles on white, the look of a lesson, with a finished sketch for each step. It suits explainers built on numbers: what the two numbers in a blood pressure reading mean, or how 150 minutes of activity fits into a week. About 25 credits.

Cartoon Explainer draws bold, expressive cartoon characters, which turns a habit into a small story, such as a commuter who starts walking to work. The AI plans recurring characters, a shared setting and a palette before any image is drawn; small details can still slip, so describe your character once near the start of the script. Make that character an everyday person, never a doctor. About 25 credits.

Documentary stock footage is the cheapest, at about 12 credits a video: real clips of people exercising, cooking, eating and visiting clinics, licensed for commercial use with nothing to attribute. It suits habit videos, where the subject is something people do. It can't show the inside of the body, and the people on screen are strangers, so never let the narration present one of them as having a condition. Mixed, which combines footage and AI images, typically costs about 14.

Science 3D, Flat Vector, Whiteboard and Cartoon Explainer can also turn each image into a short AI video clip. At about 464 credits a video, keep that for a flagship explainer rather than the daily post. Photoreal looks such as Cinematic or AI Images are a weaker fit: a realistic AI patient, doctor or hospital ward invites the question of what's real, brings YouTube's AI disclosure into play and edges toward the AI 'doctor' YouTube won't monetise (see below).

"How your kidneys clean your blood, from NIDDK, part of the US National Institutes of Health: each kidney has about a million filtering units called nephrons. In each one, a glomerulus filters the blood and a tubule returns what the body needs. They filter about 150 quarts of blood a day; only 1 to 2 quarts become urine. Science 3D look, calm narrator, name NIDDK as the source."

"What a migraine is, from the NHS: a throbbing headache, often on one side, with feeling sick and sensitivity to light and sound; some people first see zigzag lines or flashing lights. Attacks usually last 4 hours to 3 days. Say it's not known what causes migraine. Flat Vector look, calm narrator, no treatment advice, end on the NHS advice to see a GP if attacks happen more than once a week."

"How much movement adults need, from WHO's physical activity fact sheet (June 2024): at least 150 minutes of moderate-intensity activity a week. Walking, cycling, sport and play all count. In 2022, 31% of adults worldwide, 1.8 billion people, fell short. Documentary footage, upbeat narrator, name WHO as the source, end on WHO's line that any amount of activity is better than none."

Each fits the 400-character limit of the box above, and every fact in them comes from the health authority it names. Before you use one, open that page, check it hasn't changed, and keep the source's name in the narration: it's the only citation the video itself will carry.

Build every video on one question and one page from a health authority: the WHO, the CDC or the NIH in the US, the NHS in the UK, or your own country's health ministry. Their pages carry a date, such as the NHS's 'Page last reviewed', so note it, and name the source in the narration. Say whose guidance it is, because it differs between countries. The CDC says 'High blood pressure is consistently at or above 130/80 mm Hg'; the NHS usually counts it from 140/90 when checked by a healthcare professional, or 135/85 at home. Each is the guidance in its own country, and a script that blends them matches neither.

Say what's known and what isn't. Health authorities are plain about the limits of the evidence, and the narration should be too. The NHS says 'It's not known what causes migraine', and 'Migraine cannot be cured, but treatment can help'. When a draft fills that gap with a confident cause or a cure, cut the line: the source doesn't support it, and a promised cure is the kind of claim the platform rules below single out.

Explain the condition; never diagnose the viewer. 'The NHS lists a throbbing headache, often on one side, among the main symptoms of a migraine attack' is education. 'If your head throbs on one side, you have a migraine' is a diagnosis, and a narrator who knows nothing about the viewer can't make one. Treatment works the same way: say what the authority says treatment can do, never what to take, how much, or what to stop taking. Where it fits, end on the source's own advice on when to see a doctor; the NHS page on migraine, for example, says to see a GP if attacks come more than once a week.

Keep the narrator a narrator. No 'Dr.' before a name, no 'as a nurse', no 'my patients', and no doctor in the scenes: the AI that splits your script plans recurring characters, so a line like 'Dr. Lee explains' can turn into a recurring doctor on screen. A voice that says 'according to the NHS' is a narrator; a voice that says 'I recommend' is a persona.

YouTube's medical misinformation policy doesn't allow 'content that poses a serious risk of egregious harm by spreading medical misinformation that contradicts local health authority (LHA) guidance about specific health conditions and substances'. It covers prevention, including how conditions are prevented or transmitted and the safety, efficacy or ingredients of approved vaccines, and treatment, including promoting 'specific harmful substances or practices that have not been approved by local health authorities as safe or effective'. Its examples include 'Content that claims that there is a guaranteed cure for cancer outside of approved treatment' and 'Content that promotes diet and exercise instead of seeking approved treatment for cancer', and it applies to video descriptions and external links too. YouTube may make exceptions for educational, documentary, scientific or artistic content with added context, but says 'This is not a pass to promote misinformation'. A first violation likely brings a warning; repeated ones can bring strikes and a terminated channel. The policy also changes when health authorities' guidance changes, one more reason to date your sources.

YouTube's monetisation policies add 'AI Personas Related to Sensitive Topics'. It covers 'channels that use AI-generated personas to deliver information on sensitive topics', including 'any content that presents itself as a human expert providing advice to viewers on topics such as health, legal issues, finances, or politics', and says 'channels uploading this content will not be allowed to monetize'. The first example on its list is 'An AI "doctor" providing medical diagnoses, health advice, or wellness remedies'. The penalty falls on the channel, not one video, and YouTube doesn't define 'persona' further, so give the narrator no medical identity at all: no title, no credentials, no white coat in the scenes, no remedies.

TikTok's Community Guidelines don't allow 'Health misinformation that could cause significant harm, such as promoting unproven treatments that may be fatal, discouraging professional care for life-threatening conditions (e.g., vaccine effectiveness), or spreading false information about how such conditions are transmitted'. Health misinformation that can cause moderate harm, 'such as false claims about treating non-life threatening conditions like the common cold', is ineligible for the For You feed, and so is the 'Misuse of authoritative sources to push misleading conclusions, such as selectively referencing certain scientific data to support a conclusion that is counter to the findings of the study'. Quote a study's conclusion, not one number lifted out of it. 'Documentary or educational content reporting on or condemning misinformation' is on TikTok's allowed list, which is where a myth-busting video belongs.

Diet and weight videos have rules of their own on TikTok. Its guidelines on disordered eating and risky weight management make content that shows, describes or promotes 'Diets, exercises, products, or services that include exaggerated or harmful claims, such as those promising fast or dramatic results' or 'Restrictive low-calorie diets, including extended intermittent fasting' ineligible for the For You feed and age-restricted. The same goes for 'Documentary or educational content that reports on disordered eating using detailed descriptions or non-graphic imagery', so a detailed explainer about an eating disorder won't be eligible for the For You feed, however careful it is. 'Fitness routines and nutrition focused on sports or general athleticism, not extreme weight loss' are allowed.

For AI labels, the look decides. YouTube asks you to disclose AI content that looks realistic and shows a real person doing or saying something they didn't, alters footage of a real event or place, or generates a realistic scene that didn't happen. Two of its examples could come from a health channel: 'Making it appear as if someone gave advice that they did not actually give' and 'Making it appear as if hospital workers turned away sick or wounded patients'. You answer Yes under 'AI use' when you upload; for videos ShortFast posts for you, the setting is in YouTube Studio. Its examples that need no disclosure include clearly unrealistic content, animation, and using AI for the script or the captions, and it says disclosing alone won't limit a video's audience or its eligibility to earn money. A Science 3D render, a flat vector diagram or a whiteboard doodle illustrates how the body works rather than showing a real event; with a photoreal look such as Cinematic or AI Images showing patients, a clinic or a real person, answer Yes, and if you're unsure whether a scene reads as real, answer Yes anyway.

TikTok requires a label on AI-generated content that contains realistic images, audio or video. Its Community Guidelines say disclosure isn't needed for artistic styles, like anime, or for generic text-to-speech narration that isn't a recognisable voice of a known individual, so the AI narrator alone doesn't call for one. TikTok encourages labeling AI-generated content and says the setting won't affect distribution, so turning on its AI-generated content setting costs nothing. Even with a label, TikTok doesn't allow AI content that shows fake authoritative sources or crisis events: never dress a video up as an announcement from the WHO, the CDC, the NHS or a hospital.

It doesn't check facts. Nothing in ShortFast verifies a symptom, a figure or a threshold, whether you paste the script or it writes one, and an AI draft can blend guidance from different countries or repeat a popular myth. Check every line against the authority's page before you render; in script mode ShortFast narrates your checked text word for word.

AI images can draw anatomy wrong: an organ in the wrong place, a heart with the wrong number of chambers, a joint that bends the wrong way, a label in garbled text. Science 3D and Flat Vector scenes are illustrations, not medical images, so look at every scene before posting and swap any that's wrong for another image or one you upload. If a scene needs an exact diagram, upload one you have the right to use.

There are no citations on screen. The only text ShortFast adds is the burned-in captions of what the narrator says: no source card, footnote or link. Name the source in the narration ('the NHS says…') and put the link in the post text, which goes out with the video to every platform you connect.

The narration is fixed once rendered. You can edit captions, swap scenes, change music, title and post text and re-render, but a wrong figure or an overclaim in the narration means generating again; fixing only the caption would leave the narrator saying it.

A series has no approval step. An automation writes each episode, topic and script included, and posts it or emails it to you, and nothing checks those scripts either. For health, choose email delivery and read each episode against its source before you post it. The next two episodes are queued: you can edit their captions, scenes and post text, re-time or delete one, but not change its script.

None of these channels use ShortFast; they show what health explainers look like when they teach. Nucleus Medical Media makes 3D medical animations of what happens inside the body, the closest of the five to the Science 3D look, with titles such as 'How High Blood Pressure (Hypertension) Affects Your Heart' and 'How COPD Affects the Lungs'. Osmosis from Elsevier, a medical education platform, says its YouTube channel 'features general consumer health videos to educate the public about important medical concepts'; many take a single condition, such as atrial fibrillation or diabetes insipidus, and explain it in drawn illustrations. TED-Ed's animated lessons each take one question and put the educator's name in the title: 'How does your body know you're full? - Hilary Coller'. Armando Hasudungan describes himself as 'a physician passionate about medical education' and explains medicine in hand-drawn illustrations, including Shorts such as 'Pulmonology Insights: What happens inside your airways during asthma?'. Alila Medical Media makes animated anatomy mini-lectures, and its channel description says its images and videos 'are for information purposes ONLY and are NOT intended to replace professional medical advice, diagnosis or treatment'.

What they share is a clear answer to 'says who?': a named educator, a physician, a medical education platform. A faceless channel has no credentials to show, and an AI narrator mustn't borrow any, so yours answers with its sources: the authority named in the narration and linked in the post text. That is the part to copy; the scenes, the voice and the captions are the part ShortFast handles.
