Do you have the right to use it?
The footage belongs to somebody. Without their permission, the owner can have the clip taken down, and the claim or strike lands on your account.
Neither platform bans clipping as an activity. What they do is enforce two things that clips run into constantly: the copyright of whoever owns the footage, and their own rules against unoriginal, re-uploaded content. A clip is fine when both are covered.
And a third that answers both.
The footage belongs to somebody. Without their permission, the owner can have the clip taken down, and the claim or strike lands on your account.
YouTube limits monetization for reused content and TikTok keeps unoriginal content off the For You feed. A clip needs a real edit of its own.
When a creator runs a clipping campaign, they are asking for clips. Permission is given in the brief, and the brief tells you which edits they want.
Four habits.
Fair use is a defence in some countries, decided case by case, and it does not stop a claim from being filed. Commentary and criticism are where it is strongest. A clip whose only purpose is to repost the funniest minute of somebody's stream is not where you want to test it.
When a claim does land, why clips get claimed. And for how the permitted kind of clipping works, clipping campaigns explained.
You can only safely clip streamers who have given permission, usually through a campaign. Otherwise the streamer can have your clips removed.
Clipping with permission is ordinary licensed use. Without it, it is a copyright question that depends on the country and the use, which is why permission matters.
Repeated copyright strikes can lead to an account being removed on YouTube, and repeated violations have consequences on TikTok. Clipping with permission avoids the strikes entirely.
Most campaigns require a credit or a tag, and the brief says exactly how. It is worth doing even when nobody asks.
Pick a campaign, paste the source, and SnapDub turns it into edited, captioned vertical clips.
