Generation Z video marketing: what works?

Marketing to Generation Z with video usually starts from the wrong premise: that this audience only watches fifteen-second clips, on a phone, with no sound and no attention. Brazilian data from 2025 and 2026 dismantles the premise.

Generation Z prefers videos of one to three minutes, trusts creators more than any media other than friends and family, and uses video to research before deciding.

This article gathers that research and turns it into decisions about video production, distribution and tone. The educational marketing examples appear as an illustration of a sector that lives off this age bracket, but the playbook applies to any brand that needs to speak to people between 16 and 29.

Who is the Generation Z that watches video in Brazil?

The Generation Z that watches video in Brazil is the audience born between the late 1990s and the early 2010s, today roughly 14 to 29 years old, which grew up with YouTube as television and the phone as its main screen.

It is a group that is almost entirely connected and treats social platforms as a source of information, not only of entertainment.

The territory is large. Brazil has 185 million internet users, and YouTube ads reach 81.1% of them, according to DataReportal.

Among the youngest, penetration is even higher: TIC Kids Online Brasil 2025 found that 92% of people aged 9 to 17 use the internet, and that YouTube, Instagram and TikTok are accessed several times a day by almost half of them.

Video has already beaten television in this bracket. A Deloitte survey in the United States showed that 56% of Generation Z prefers video on social platforms to TV and cinema. In Brazil, the shift shows up on the brand side: in the 2025 VML/BAV ranking, Google, YouTube and WhatsApp are Generation Z’s three favorite brands.

Games are part of the repertoire, not a niche. Pesquisa Game Brasil 2026 shows that 75.3% of Brazilians play games and that Generation Z is the largest group, with 36.5% of gamers. Anyone producing video for this audience is competing with game streams and gaming creators for the same attention.

So far, this is the wide-angle picture. The post on marketing to Generation Z covers values and channels in a broad sense; this article focuses on video, where the data is more specific.

What video format does Generation Z prefer?

Generation Z prefers video of medium duration and watches on different platforms than the market assumes. In the Opinion Box survey with Influency.me, with 2,000 respondents, videos of 1 to 3 minutes were the favorite format for 32%, ahead of long-form video (22%), Stories (22%) and videos under 1 minute (18%).

The figure inverts the intuition that shorter is always better. The under-one-minute format is the least preferred of the four, and the two formats longer than a minute add up to 54%. Generation Z does not reject duration; it rejects content that does not justify its duration.

The platform is also a surprise. In the same survey, Instagram is the preferred platform for video (49%), followed by YouTube (30%) and TikTok (16%). TikTok dominates the conversation about young people, but it does not dominate stated preference. For video production, that means Reels and YouTube videos are the core, and TikTok is the extension.

Long-form video has a job of its own. On YouTube, it is what AI cites and what sustains search, as detailed in SEO for video. Long-form and community platforms, such as Bilibili, report more than 110 minutes of daily use with an audience whose average age is 26.5. Long attention exists; it is just selective.

The production rule that comes out of this is a single one: make the video as long as the subject requires, not as long as the platform’s format suggests. A well-made three-minute tutorial beats a fifteen-second cut that teaches nothing.

Why is a creator worth more than a brand for Generation Z?

A creator is worth more than a brand for Generation Z because the trust was built in the relationship, not in the message. In Brazil, 91% of people aged 16 to 29 follow at least one influencer, and influencers are the second most trusted source of recommendation, behind only friends and family, according to Opinion Box with Influency.me.

Trust converts into purchases. In the same survey, 65% have already bought on an influencer’s recommendation. In another Opinion Box survey, on social platforms in general, 69% of Brazilians have bought on a recommendation from social media, and 50% use YouTube to learn. The creator’s video is a class and a shop window at the same time.

YouTube measured the same phenomenon from the platform side. In a Talk Shoppe survey of 600 people aged 18 to 26 in Brazil, 89% of Generation Z agrees that YouTube creators publish content it can trust. It is not trust in the platform, it is trust in the people who publish on it.

For content marketing, the conclusion is structural. A brand that speaks alone on video competes for attention with creators who already have the audience’s trust. A brand that speaks through creators, with an editorial brief and freedom of format, enters the conversation that already exists. It is the difference between paid social as interruption and paid social as partnership.

User-generated content follows the same logic on a smaller scale. A customer, student or user testimonial on video, produced simply, tends to convert better than an institutional piece, and the reason is the same: Generation Z trusts those who lived it, not those who sell it. The mechanics are in video content for student recruitment.

How does Generation Z use video to search and decide?

Generation Z uses video as a step in search, not only as entertainment: it searches on Google and in AI, confirms on video on YouTube or TikTok, and decides. It is the age bracket that searches the most, according to Google Brazil, and the one that uses AI the most, which makes citable, findable video a piece of the buying journey.

Search volume is the first data point. Fabio Coelho, president of Google Brazil, stated in 2025 that Generation Z searches more than any other age bracket, out of a total of 5 trillion searches a year, 15% of them never seen before. The idea that this audience has abandoned Google does not hold up in the numbers.

AI has entered the routine. A Google survey with Ipsos in Brazil, with 2,750 internet users, showed that 90% of Generation Z uses AI tools daily, to research complex subjects and to compare products and prices.

In the United States, McKinsey found that 60% of Generation Z regularly uses the AI summary at the top of search, against 29% of boomers.

The search ends in video. Opinion Box shows that 56% of consumers look for reviews on YouTube when they are unsure about a purchase, and that 42% of Brazilian TikTok users use the platform to stay informed and 49% to discover new things. The person reads the AI answer and confirms it on video with someone they trust.

That behavior ties video to SEO for social media. If Generation Z searches and the answer it finds is a video, then that video’s title, description and transcript are the brand’s landing page. A video with no search intent in the title is a video outside the journey.

Which mistakes drive Generation Z away in video?

The mistakes that drive Generation Z away in video are the ad disguised as content, the short cut that delivers nothing, the missing captions and the script written by the brand and put in the creator’s mouth. All of them share one root: treating video as interruption media for an audience that treats it as a source.

The first mistake is the disguise. Generation Z spots advertising inside content quickly, and the research on trust in creators only holds while the creator still sounds like themselves. A paid collaboration with the brand’s script breaks the trust contract and takes the creator’s credibility with it. Editorial brief, yes; script, no.

The second mistake is confusing short with efficient. As the preference data shows, the under-one-minute video is the least favorite format. Cutting a tutorial to fifteen seconds so it fits a feed format may win reach, but it loses the usefulness that would bring the audience back.

The third mistake is ignoring the people watching without sound. Research by Verizon Media with Publicis found that 69% of people watch video without audio in public places. Captions are not optional accessibility for this audience; they are the condition for the video to be watched on the bus.

The fourth mistake is the brand talking about itself. Generation Z looks for video to solve something, and the brand that teaches, shows behind the scenes or answers a real question earns the attention span that the brand introducing itself does not.

On community platforms, the verdict shows up in comments over the video in real time, as happens with Bilibili’s danmaku.

How does educational marketing speak to Generation Z in video?

In educational marketing, speaking to Generation Z in video means answering on video the questions candidates ask before choosing a program, using students and alumni as creators, and keeping the enrolled community on continuous content. It is a sector-level example of an audience education competes for by nature.

On-campus higher education is still this generation’s territory. According to Semesp’s Higher Education Map, 61.9% of students in private on-campus programs are up to 24 years old, while in private distance learning most are 25 or older. In student recruitment for on-campus programs, Generation Z is the core audience, and it decides with video.

The application follows the three rules the data gives. Medium duration: an open three-minute class on “what a data engineer actually does” is worth more than a fifteen-second institutional cut.

Creator voice: a third-year student showing the lab converts better than the dean speaking live. Search intent: the video title is the question the candidate asks AI.

In student retention, video becomes community. Q&A livestreams before exams, series on internships and careers with alumni, and academic guidance content keep the bond with people who are already enrolled. Since retention costs less than recruitment, this is the video front with the best return per hour of production.

Frequently asked questions about Generation Z video

What changes in results when you get Generation Z video right?

Getting Generation Z video right changes results on two fronts: acquisition cost falls, because the creator’s trust replaces part of the paid frequency, and the content works in search, because a well-titled video is found on Google, in AI and in platform search long after it is published. Video stops being an expense and becomes an asset.

The path is to follow the data, not the intuition. One to three minutes as the default, long-form video for search and citation, Instagram and YouTube as the core, creators with editorial freedom, captions on everything and a title that carries the question the audience asks. Every decision has research behind it, and none of them depends on guessing what “young people” want.

If Generation Z trusts those who lived it and not those who sell it, the video format that converts best is the testimonial from someone who is already a student or a customer. The mechanics of producing, distributing and measuring that kind of content are in why video content made by your audience sells, the natural companion to this reading.
