Gambling Clip Disclosure Requirements: The On-Screen Spec for a 9:16 Frame

This page is about short-form video clipping — vertical clips cut from streams or long videos and posted by creator accounts. Not press clipping or media monitoring, not audio clipping, not the Los Angeles Clippers, and not the black-market practice of laundering ads through fake accounts. It is the production spec: what the frame has to show, at what size, for how long, and which instrument says so.

Four elements exist across the world's gambling advertising rules, and no single market requires all four at once.

One piece of United States guidance belongs here because it governs rendering rather than existence. 16 CFR §255.0(f) states that “in any communication using an interactive electronic medium, such as social media or the internet, the disclosure should be unavoidable.” The FTC's own Disclosures 101 guidance puts it in production terms: “if making an endorsement in a video, the disclosure should be in the video and not just in the description.”

Four regulators have written down a measurable on-screen specification for gambling advertising. Every other market reviewed for this page sets a standard you cannot measure.

Spain. Real Decreto 958/2020 of 3 November 2020 (BOE núm. 291, 4 November 2020) requires the responsible-gambling message and the age warning to be “claramente visible en toda la comunicación comercial” — clearly visible throughout the whole commercial communication — or else to “ocupar toda la imagen, al menos durante dos segundos”, occupying the whole image for at least two seconds. Article 2 extends the decree to “páginas web y redes sociales”, so it binds social video and not only broadcast.

South Australia is the most prescriptive of the four. The Authorised Betting Operations Gambling Code of Practice, clauses 16 and 19, effective 31 March 2024, requires the prescribed tagline in digital advertising to be “displayed in upper case Arial bold 60pt which occupies at least 1/3rd of the canvas”, and the call-to-action message “in sentence case Arial bold 40pt which occupies at least 1/3rd of the canvas” — upper case for one, sentence case for the other. Video carries white text on black under cl. 16(3); digital and print run black on white. Both blocks sit at the end of the advertisement.

The 15-second rule in South Australia runs the opposite way to how it is usually reported. Clause 16(2) states that television and video advertising “that is 15 seconds or less, may not include the short-form call-to-action message”. A short ad is relieved of that element, not loaded with it. The voiceover obligation attaches to advertising longer than 15 seconds, at cl. 16(1)(a). This is South Australian state law, not a national Australian rule.

Massachusetts is the only United States jurisdiction found to set a percentage-of-frame rule, and it applies to sports wagering advertising under 205 CMR 256.06(4)(d). One route keeps the responsible-gaming message visible for the entire advertisement at a font height of “at least 2% of the height or width, whichever is greater, of the image that will be displayed”. The qualifier does the work: on a vertical clip the greater dimension is the height. The alternative route, at subsection (ii), requires both 2% during the advertisement and 8% on a “dedicated screen shot visible for at least the last three (3) seconds”. Both, not either. The clock on option (ii) starts at the first depiction or verbal reference to sports wagering rather than at the start of the ad.

Brazil requires one of three Ministry of Finance warnings, and it specifies the geometry. Portaria SPA/MF nº 1.964 of 3 July 2026, art. 1º (DOU 10 July 2026, in force 17 July 2026), amends art. 13 of Portaria SPA/MF nº 1.231/2024 so that warnings “devem estar na horizontal, serem claras, legíveis e proporcionais… e ter um mínimo de 10% (dez por cento) do comprimento ou tamanho do anúncio.” The three permitted wordings are “Ministério da Fazenda adverte: Apostar pode causar dependência”, “…Apostar faz você perder dinheiro” and “…Aposta não é investimento”.

Two things about the Brazilian rule are missed almost everywhere. The 10% is measured against “comprimento ou tamanho” — length or size — and specifically not against area, which changes the answer by an order of magnitude. And the 10% is not a 2026 innovation: it already sat in art. 13 §1º of Portaria SPA/MF nº 1.231/2024, in force from 1 August 2024. What 2026 added was the horizontal requirement and the three fixed wordings.

Brazil separately prohibits the display of winning bets, including in cash, under Portaria Interministerial MF/SECOM/MJSP nº 73 of 10 July 2026. That is a content ban rather than an on-screen specification, so it is noted and left there.

Whether a clip may run in a given market at all is a different question from what the frame must carry, and it is covered in keeping a campaign inside licensed markets. Who is on the other side of the screen is a third question again — the audience-age rules, and the evidence that proves them, are in how to evidence age composition.

Outside those four, the rule tells you the effect to achieve and refuses to tell you the dimension.

The United Kingdom publishes no numeric on-screen specification anywhere. Gambling advertising falls under CAP rule 16.3.12, in force 1 October 2022, and the ASA's affiliate marketing guidance of 22 March 2023 requires advertising to be “obviously identifiable as advertising upfront”. The ASA adds that “in shorter media such as social media posts, the ASA is less likely to accept that the affiliate advertising can be separated out from the rest of the content”, and that a disclaimer at the bottom of a post is “unlikely to be sufficient”. The only numeric superimposed-text guidance in the UK is BCAP's, which is television-only and not gambling-specific, so it does not bind a vertical clip.

United States federal guidance gives you “unavoidable” at 16 CFR §255.0(f) and nothing else. The FTC specifies no seconds, no percentage and no font size anywhere.

Germany mandates no on-screen element at all. GlüStV 2021 §5(3) bans advertising for virtual slots, online poker and online casino games “täglich zwischen 6 Uhr und 21 Uhr” — daily between 06:00 and 21:00 — across broadcast and internet, and §5(6) bans affiliate remuneration that varies with turnover or deposits. The word “Influencer” does not appear in §5: influencer gambling advertising is not banned outright in Germany, it is caught by the daypart rule, as the Oberverwaltungsgericht Magdeburg held in 3 M 87/23 on 19 December 2023.

The Netherlands runs an audience test rather than a frame rule. Article 2ab(2)(c) of the Besluit werving, reclame en verslavingspreventie kansspelen requires proof that “ten minste 95%” of the persons reached had attained “de leeftijd van 24 jaar”.

Ontario sets targeting and content requirements at Standard 2.03 of the AGCO Registrar's Standards, last updated 14 May 2026, with no size, duration or placement requirement.

On TikTok you cannot use the built-in disclosure, because the policy that governs it bans your category.

TikTok's Branded Content Policy lists “Gambling — Including online gambling, casinos, social casinos, sports betting, fantasy sports, bingo, lotteries” among its prohibited industries. The automatic “Paid partnership” label is a branded-content feature, so if branded content for the category is not permitted, the label is not available to it. The policy's only openings are narrow and are not the creator's to take: national lotteries, and sports betting or fantasy sports, where the brand works with a TikTok sales representative to establish eligibility first. A casino or iGaming operator has no such route, so the disclosure has to be burned into the picture instead. TikTok's Community Guidelines add that “we do not allow the facilitation or marketing of gambling or gambling-like activities”, and gambling content is age-restricted to 18+ and ineligible for the For You feed.

YouTube is the only major platform that publishes a hard number here, and it is not one to rely on. YouTube Help states that “whenever you mark your video as containing paid promotions, we automatically show viewers a disclosure message for 10 seconds at the beginning of the video”, and the policy covers videos, descriptions, comments, live streams and Shorts. What YouTube does not say anywhere is what happens on a Short shorter than 10 seconds. A 10-second overlay on an 8-second Short is undefined behaviour, and that is not a compliance strategy.

TikTok's advertising side confirms the same asymmetry from the other direction. Its Gambling and Games ad policy, last updated June 2026, requires licensed advertisers to “include all legally mandated gambling disclaimers and taglines” — and specifies nothing about how they must be rendered. No font, no size, no duration, no contrast, no percentage of frame. The platform mandates the furniture and leaves every dimension of it to the regulator. Its only rendering rule is generic: “the ad must be legible and of a high resolution.” Why the paid route is closed to most operators in the first place is covered in why iGaming ads are closed.

So on TikTok the disclosure is burned in because it must be, and on YouTube it is burned in because the platform's version cannot be relied on to fit.

Compliance text has to sit inside the part of the frame the app does not cover, and no platform will tell you in writing where that is.

TikTok's stated position is that the boundary moves: “the safe zone size is determined by the dimension (vertical, horizontal, or square), ad caption length, and any additional formats used” (TikTok in-feed ad specifications, last updated June 2026). Its Creative Center describes the safe zone only in pictures — “there's a number of fixed elements in the UI that can potentially block your creative ads” — and ships the geometry inside downloadable template files. Google publishes a safe-area reference at 1080 × 1920 whose pixel measurements exist only inside the image. Meta's own safe-zone documentation could not be read at all.

What is specifiable is the regulation, and that converts cleanly.

Two placement rules follow, and neither is a number. Put compliance text in the upper-middle of the frame, above the caption block and clear of the right-hand action rail, because those are the two regions every vertical interface uses. And never let the regulator's element be the thing that gets cropped: if something has to be sacrificed to the interface, sacrifice the brand's own text.

A 20-second vertical clip at 1080 × 1920, promoting a licensed operator, paid. Four markets, four different frames.

Massachusetts, taking option (ii). The responsible-gaming message runs at 2% of the greater dimension — against 1,920 pixels that is just over 38 pixels of font height — from the first reference to wagering onward, and a dedicated screen shot carries the same message at 8%, just over 153 pixels, across the final three seconds. Both, not either.

Spain. The message and the age warning are either clearly visible throughout the clip, or they occupy the whole image for at least two seconds. Two seconds of a 20-second clip is 10% of the runtime given over to a full-frame end card.

South Australia. The tagline block takes at least a third of the canvas and the call-to-action block at least another third. Assuming each block spans the full frame width, that is at least 1,280 of 1,920 pixels of height, or two-thirds of the frame, at the end of the ad. At 20 seconds the clip is over the threshold, so the voiceover obligation applies as well. Had it been 15 seconds or less, the call-to-action message would have been omitted instead.

Brazil is the ambiguous one, and it is worth understanding before you design. Ten percent of “comprimento ou tamanho” is 192 pixels measured against the 1,920-pixel height and 108 pixels measured against the 1,080-pixel width. The instrument does not say which dimension applies to a vertical video. That is an ambiguity in the rule itself, not a choice to make quietly.

Every pixel and percentage figure in this example is Lumina Clippers' own arithmetic on the published rule, applied to a 1080 × 1920 frame. The regulations state percentages, point sizes and seconds; none of them states a pixel value.

A burned-in element survives redistribution. Everything else does not.

A caption disclosure does not travel, because the reposter writes a new caption. A platform label does not travel either, and on TikTok it was never available to a gambling clip in the first place. A duet or stitch reframes the picture, so an element placed near the edge of the original frame can end up cropped, letterboxed, or covered by the second creator's camera.

The only regulator guidance that speaks to fragmentation is the ASA's rule for multi-part Stories: “if advertising content spans across several stories, you should label each relevant story in the series.” The principle transfers — each fragment a viewer can encounter alone has to carry the label alone — but it is guidance written about Stories, not a rule about duets, and it should not be presented as more than that.

The ASA also holds that a label visible only after clicking “more” in a TikTok video is insufficient. That closes the caption route on its own, regardless of whether the caption survives a repost.

The working rule, and it is a production heuristic rather than anything a regulator published: design the element to stay legible after a 25% crop on any edge, and treat every clip as though it will be reposted without its caption. A clip network's entire mechanism is that clips get reposted.

We could not find a published measurement of what compliance furniture costs in retention. Nobody appears to have run it. So this section offers craft rather than statistics, and no percentage here is invented to fill the gap.

What is verifiable is reading speed, and two independent bodies converge on it. TikTok's creative best practices recommend “displaying 5-10 words per second when using text”. BCAP's superimposed-text guidance for television sets 5 words per second with a two-second recognition floor for nine words or fewer, and three seconds for ten or more. Different bodies, different media, same order of magnitude, which is about as close to a validated figure as this area offers.

One related point, and then it is somebody else's page: overlaid text that does more than describe the action is also what Instagram counts toward a material edit, covered in Instagram's unoriginal content policy.

This is what an editor checks before export, not the evidence file a regulator asks for afterwards — that sits in keeping a campaign inside licensed markets.

Choosing a partner who runs this before export rather than after a takedown is most of the decision, and the criteria are in how to choose a clipping agency.
