The YouTube Shorts copyright survival guide: "just credit the source" is how channels get deleted

The fastest way to lose a channel isn't the algorithm. It's copyright. Three strikes and the channel is gone, and any channels linked to it go with it. Yet half the copyright "common knowledge" passed around among creators is wrong. "Just credit the source." "Under 10 seconds is fine." "It's okay if I don't monetize." None of those are in the law.

This post is general information, not legal advice. For an actual dispute, talk to a lawyer or the Korea Copyright Commission.

Claims and strikes are completely different things

Copyright trouble on YouTube comes in two forms. Mix them up and every move you make will be wrong.

According to the YouTube Help Center, a copyright strike expires 90 days after you complete Copyright School. Collect three strikes within 90 days and the channels tied to your account are subject to termination, and you can't create new ones. If the rights holder requested a "scheduled takedown," you can avoid the strike by deleting the video yourself within 7 days.

Two rules that apply only to Shorts

Shorts over 1 minute and Content ID claims. After Shorts could run up to 3 minutes, any short over 1 minute with a Content ID claim was blocked worldwide, no matter what the rights holder's policy said. That rule changed on September 24, 2026. New 1–3 minute Shorts with a claim are no longer blocked automatically and can still play. Shorts that are blocked worldwide, though, still can't earn revenue.

Shorts audio. Songs you pick from the Shorts audio library inside the YouTube app can mostly be used for up to 90 seconds in a 3-minute short; some tracks are capped at 60 or 30 seconds. Copyright-safe tracks from the YouTube Audio Library don't get claimed. On the other hand, downloading a song from a music site and baking it into your video in an editor has nothing to do with these allowances. If the rights holder blocks it, it's blocked.

Korea's Copyright Act: quotation and fair use

Separate from YouTube's rules, if you use footage in Korea, Korea's Copyright Act applies. There are two provisions creators can lean on.

• Article 28 (Quotation from works made public): You may quote a work for purposes such as news reporting, criticism, education, and research, within a reasonable scope and in line with fair practice.
• Article 35-5 (Fair use of works): You may use a work when it doesn't conflict with the normal way the work is exploited and doesn't unreasonably harm the author's legitimate interests. Four factors are weighed.

1. The purpose and character of the use (is it criticism or education, or does it let people enjoy the original as is?)
2. The nature and use of the work
3. The amount and importance of the portion used relative to the whole
4. The effect on the current or potential market or value of the original

That takes down three common myths.

• "Just credit the source." Credit is one of the duties you owe when you quote. It doesn't replace permission. Infringement with credit is still infringement.
• "Under 10 or 30 seconds is fine." The law has no seconds-based rule. Even 3 seconds counts against you on amount and importance if it's the most important moment of the video (the winning goal, the drama's big twist).
• "It's fine if I don't monetize." Being non-commercial only helps a little on the first factor. If your short makes people skip the original, you lose on the fourth.

Genre by genre

TV, dramas, variety shows, and sports

Broadcasters and sports rights holders are among the most aggressive users of Content ID. A short stitched together from clips will almost certainly get caught. YouTube's own policy lists "clips from your favorite show stitched together with no narrative" as an example of reused content and excludes it from monetization. If you want to work in this genre, look for ways the broadcaster officially allows (official clip sharing, partnerships), or make your face and your analysis the star instead of the footage.

Movies

A review built on a few seconds of the trailer and a recap that stitches together a movie's key scenes to tell the whole plot are completely different things legally. The recap stands in for the reason to watch the original, which puts it in the worst position on the fourth factor (market impact). If you review, stay within the official stills and trailers the studio released, and keep your critique at the center.

Games

Every game publisher has its own policy on gameplay footage. Riot Games, in its Legal Jibber Jabber, allows you to earn ad revenue from gameplay videos as long as you follow its policy. Nintendo's game content guidelines allow videos with creative input or commentary and prohibit simple copies. If there's a game you cover a lot, read that publisher's creator policy page all the way through at least once. Licensed music inside a game can still be claimed by the music's rights holder, even if the publisher allows the footage.

Other people's shorts and streamer clips

Clipping another creator's video comes down to permission, full stop. Post without it and you get everything at once: a copyright strike, removal from YouTube monetization, and exclusion from Instagram recommendations. Get permission in writing, not just verbally (see the request template below).

It's not just music that gets you flagged

Fonts

"Free" fonts are free in very different ways. Some are fine for print but not video, some are personal use only, and some can't be used in a logo. For fonts in your captions and thumbnails, check the license for video use and commercial use, both, and screenshot that page.

Portrait rights and publicity

People you film on the street, customers in a shop, passersby caught on camera all have portrait rights. If a recognizable face is the focus of your video, get consent or blur it. Using a celebrity's name, face, or voice for your own business (ads, product promotion) without permission can fall under the publicity provision of Korea's Unfair Competition Prevention Act, in force since June 2022. The classic case: a short with a celebrity's face slapped on the thumbnail so it works like an ad.

Scenes made or altered with AI

When you upload realistic synthetic or altered content (a real person saying something they never said, a fake event at a real place, and so on), YouTube requires you to mark it as "Altered or synthetic content" on the upload screen. For ads, the Korea Fair Trade Commission (KFTC) has also required a "virtual person" label on endorsement and testimonial ads featuring AI virtual people since June 2026.

How to ask for permission: a message you can copy

Send this to the creator whose clip you want to use. Screenshot the reply and keep it in a folder for that video.

Hi, I'm [Y], and I run the [X] channel. I'm reaching out because I'd like to edit 03:12–03:58 of your video "[Title]" ([link]) into a vertical short and post it on my channel ([link]). The short will include a link to the original and your channel name, and I'll add my own commentary captions. My channel is monetized. Where: YouTube Shorts, Instagram Reels, TikTok / How long: indefinitely from the posting date (or [N] months) If you're okay with this, please reply to this email with "I give permission." If you ever change your mind, I'll take it down.

What your request can't leave out: which segment, where, for how long, and whether the channel is monetized. "Can I use it?" "Sure" proves nothing later.

Pre-upload checklist

• I shot every scene in the video, or I have the right to use it on record
• The music is in-app, copyright-safe, or licensed
• I have permission for other people's clips, and I screenshotted the reply
• Critique or commentary is the star of the video, and I didn't lift the original's key scene wholesale
• My caption and thumbnail fonts allow video and commercial use
• Recognizable faces of private individuals have consent or are blurred
• I didn't use a celebrity's face or name like an ad
• If there's a realistic AI-generated scene, I marked it as "Altered or synthetic content"
• If it's sponsored, I checked "Includes paid promotion" and added an on-screen disclosure

If you cut shorts from long-form video, you're safest when the source is your own. Shorts pulled from a podcast, lecture, or interview you recorded are an asset you can reuse endlessly with no rights worries.

Frequently asked questions

How many seconds of a song can I use in a short?

Korea's Copyright Act has no seconds-based rule. Songs you pick from the Shorts audio library in the YouTube app can mostly be used for up to 90 seconds in a 3-minute short (60 or 30 seconds for some tracks), and copyright-safe tracks from the Audio Library don't get claimed. Baking a song you got elsewhere into your video has nothing to do with these allowances.

When does a copyright strike go away?

It expires 90 days after you complete Copyright School. You can also ask the rights holder to retract it, or file a counter notification if the removal was a mistake or the use is fair use. Three strikes within 90 days and the channel is subject to termination.

If I credit the source, am I in the clear?

No. Credit is one of the duties you owe when you quote. It doesn't replace the rights holder's permission. Quotation and fair use are judged on the whole picture: the purpose of the use, the amount and importance of the portion used, the effect on the original's market, and more.

Does a Content ID claim hurt my channel?

A claim usually isn't a copyright strike. Depending on the rights holder's policy, that video's revenue goes to them or it gets blocked in certain countries. But if you dispute without grounds and the rights holder escalates to a formal takedown request, it can become a strike.

My short over 1 minute got blocked for copyright.

Since September 24, 2026, new 1–3 minute Shorts with a claim are no longer blocked automatically. For Shorts uploaded and blocked before that, remove the flagged part, or dispute it if you have grounds.

One last thing

Today, run your channel's ten most popular shorts through the checklist above. If even one line trips a video, fixing it or taking it down yourself before a strike arrives is the cheapest option.
