Where copyrighted music hides in a video
Most copyright problems in a finished video aren't the song you chose on purpose. They're the ones you stopped hearing after the tenth pass through the edit:
- Background music while filming. A shop, a gym, a car radio, a wedding DJ. A few seconds is enough for a match.
- Music inside other footage. B-roll from an old project, a screen recording with a tab playing music, a game with a licensed soundtrack.
- Templates and presets. Some editing templates ship with a track attached. It stays in the export unless you remove it.
- Re-uploaded short videos. A TikTok or Reel saved to your phone carries the in-app sound with it, without the licence.
- The intro or outro. A song you used once, years ago, that's now on every video.
A video copyright checker is most useful at the very end, on the file you're about to upload, because that's the version the platform will scan.
What happens when a platform finds music in a video
Each platform scans uploads against music rights holders have registered, and each reacts differently:
- YouTube places a Content ID claim. Depending on the rights holder's choice, ads run for them instead of you, the video is blocked in some countries, or they just track it. A claim usually doesn't affect your channel; a strike is a separate, legal process. See the YouTube copyright checker.
- TikTok mutes the audio or removes the video. See the TikTok copyright checker.
- Instagram and Facebook follow Meta's music guidelines: content with unlicensed music may be blocked, muted or removed. See the Instagram copyright checker.
YouTube's Content ID also matches visual content, not just audio. If your video uses clips from films, TV, sports or other creators, it can be claimed even if the soundtrack is clean.
How the video check works
- Pick the video. MP4, MOV and other common formats up to 200 MB. Your browser decodes the soundtrack locally.
- Free clip check. We cut 12 seconds, from the moment you choose or the middle of the file, and identify the recording in it. Use it to answer "what is this song?" for one spot.
- Full scan. For the whole video, the soundtrack is split into 12-second segments and every one is checked. The report lists each song with the timestamps where it plays, so you know exactly which part of the timeline to cut, mute or replace.
Every match comes with the title, artist, label or rights holder, ISRC when there is one, and a risk level: High risk for commercially released recordings, Check license for production-library music, No match when nothing in our catalogue of more than 150 million tracks lined up.
What it can't tell you
We identify recordings with audio fingerprinting through ACRCloud. That's precise for released music, and it has limits:
- The picture. Footage, images, logos and on-screen text aren't checked.
- Covers and live versions. A new recording of a song has a different fingerprint. The song itself is still copyrighted.
- Heavy edits. Sped-up, slowed or pitch-shifted audio may stop matching.
- Music under loud voiceover or noise. Less music to fingerprint means a lower chance of a match.
- What a platform will decide. Content ID, TikTok and Meta use their own databases and the rights holder's settings. A match with us is a strong signal; no match is not a clearance.
How often it gets it right in practice is on the accuracy page. If you want to know whether you're allowed to use a song, rather than which song it is, read how to tell if a song is copyrighted.
Fixing a video before you upload
- Cut or mute the matched section if the music isn't important to the scene.
- Replace the track with music from the platform's own library, or a stock track whose licence covers where you're posting.
- Keep licence receipts for anything you bought, so you can dispute a claim on licensed music.
- Check the export again. It costs one free clip to confirm the problem section is clean.
