The video is permanent. The link in it should not have to be.

Why do YouTube creators put QR codes in their videos?

Because a lot of your audience is watching on a screen they cannot tap.

In February 2025 YouTube’s CEO said that television had passed mobile and desktop as the primary device for YouTube viewing in the US, measured by watch time, at more than a billion hours a day on TVs. That number needs its qualifiers kept attached, because by global view count mobile is still far ahead. But watch time is the number that matters for this, since the person deep into a twenty-minute video on a living-room screen is exactly the person who cannot click anything.

On a TV there is no clickable description, no comment section within reach, and no practical way to type a URL. What there is, almost always, is a phone somewhere near the viewer. A code on screen is the only bridge from one to the other that takes less effort than giving up.

The same thing happens on desktop, for a different reason. Someone with the video on a second monitor while they play a game is not going to alt-tab, find the description, and copy a link. They will point their phone at the screen, because that is genuinely easier.

What makes a QR code in a video different from one on a poster?

You can reprint a poster. You cannot re-render a video.

This is the part most creators have not thought through, and it is worth being precise about it, because the precision is the whole point.

Once a video is published, YouTube Studio lets you do exactly two things to the footage: trim it and blur parts of it. There is no operation that swaps the video file for a corrected one. So a QR code you rendered into the frames is in those frames permanently, at whatever URL it encoded on the day you exported.

It gets more locked as the video does better. YouTube’s own help page says that for unedited video with over 100,000 views, you may not be able to save changes at all except to blur faces, unless you are in the Partner Program. The more successful the video, the fewer edits it will accept.

And the escape hatch is worse than it sounds. You can always delete and re-upload, but a trim keeps the URL, the view count, and the comments, while a re-upload keeps none of them. You would be trading every view and every comment that video has ever earned for the ability to fix one link.

So a printed menu is actually the easier case. A restaurant with a bad code can reprint. You cannot.

Does YouTube’s own QR code feature solve this?

For shopping, largely yes. For everything else, no.

In October 2025 YouTube added in-video QR codes to its TV app so creators can tag products and viewers can scan through to a product page. It is a good feature and it is aimed squarely at YouTube Shopping, which is where it sits and what gates it.

That covers the merch and affiliate case. It does not cover your Discord invite, your newsletter signup, your Patreon, a sponsor’s landing page, your own site, or a link to the thing you spent the whole video talking about. Those are still yours to solve, and they are most of what creators actually want to point people at.

If you are tagging products, use YouTube’s feature. It is built for it and it is free. This page is about the other links.

Why does the destination need to change later?

Because everything you would point at moves, and the video does not.

Think about what you would put behind a code in a video published today, and where those things will be in two years:

• A Discord invite. Standard invites expire. Servers get remade.
• A newsletter. Creators move between platforms constantly. The signup URL changes with them.
• A sponsor. The campaign ends, the tracking link dies, and the deal is over long before the video stops being watched.
• A product page. Restocks, redesigns, new URLs, a whole new store.
• A links page. These get rebuilt more often than anything else on this list.

Meanwhile the video keeps playing. Back catalogue is most of a channel’s watch time, and a video from three years ago is still collecting views today with whatever you put in it.

A static QR code has the destination baked into the pattern, which means the URL you exported in 2026 is the URL it will still be sending people to in 2031. A dynamic code encodes a redirect instead, so the pattern in the frames never changes while the destination behind it can be updated any time. That is the only version of this that survives contact with a back catalogue.

Buy it once, because the video is going to outlive the subscription

Here is the part that decides which kind of dynamic code to use.

Most QR services rent you the redirect. You pay monthly, and if you stop, the code stops. On a poster that is annoying. On a back catalogue it is worse, because every video you ever published with a code in it goes dark at once, and you cannot fix a single one of them by editing anything. The codes are in the frames. The only thing that was ever changeable was the redirect, and that is the exact thing the bill was holding.

A Graklink dynamic code is a one-time $7.99. There is no plan on the code to lapse. A published Graklink code never stops redirecting because of a billing event, and only two things can ever stop one: an acceptable-use violation like phishing or fraud, or you deleting your own account. Money is not on the list.

For a channel, that maps onto the actual shape of the problem. The videos are permanent, your income is not necessarily steady, and the code needs to still work during the quiet year.

How do you make one that actually scans on a TV?

Design it for someone across the room, not for yourself at a monitor.

• Make it much bigger than feels right. Your viewer may be eight or ten feet from the screen. A code that looks generous in your editor looks tiny from a couch.
• Hold it still, and hold it long enough. Give it several seconds of stable screen time. A code that flashes past in one second is decoration. If it moves with an animation, it is unscannable while it moves.
• Give it high contrast and real quiet space. Dark code on a light panel, with clear margin around it. Do not lay it over footage, a gradient, or anything busy.
• Respect compression. Video encoding softens fine detail, and QR codes are fine detail. Bigger and simpler survives the encoder. A short destination URL makes a less dense pattern, which compresses better.
• Say what it is. A code with no caption gets ignored. Tell people what they get: “Scan for the parts list,” not “scan me.” Our guide to what to write next to a code goes deeper on this.
• Test it the way a viewer will. Upload the video, play it on an actual television, and scan from the sofa with a normal phone. Do not test the source file on your desk. The uploaded, compressed, TV-rendered version is the one your audience gets.

Recommended setup

One dynamic code, pointed at a page you control, reused across your videos.

Most creators do not need a code per video. One code behind a simple links page is easier to manage and means every video you have ever published can be repointed at once by editing a single destination. If you want to know which video is driving scans, make one code per video instead and accept the extra bookkeeping.

Start with a free static code if you are pointing at something genuinely permanent, like your channel URL. Buy the $7.99 dynamic code the moment the destination is anything that might move, which in practice is almost always.
