The Four Factors of Fair Use in Plain Language

Purpose and character of use

Fair use turns on purpose first. Nonprofit education or commentary can help, but commercial goals do not block it. The key is whether the new work is transformative: does it add new meaning, context, or insight instead of copying the original?

Good faith editing counts. Skipping ads, cutting fluff, or adding analysis shifts character. Bad faith, like copying to avoid buying access, counts against you. Ask why you need the clip, not just that you want it.

Nature of the original work

Published factual works allow more leeway than unpublished creative works. A news clip is treated differently from a private script or a full song mix. Still, no category gives a free pass.

Highly creative works get more protection. That does not ban quoting a scene, but it means your need must be clearer. Focus on facts or specific lines that prove your point.

Amount and substantiality used

Amount is not a fixed number. Use the smallest portion needed for your argument. Sometimes a single shot is too much if it is the 'heart' of the work, but rarely used in a new context.

Quality can outweigh quantity. Avoid the most recognizable moment unless no substitute exists. Trim to frames, not seconds, when possible.

No single factor decides fair use; the court weighs all four together.

Market effect on the original

Will your video replace the original in the market? If viewers watch your take instead of buying the source, that hurts fair use. Criticism can limit sales in rare cases, but blocking criticism is not the goal.

Consider licensing markets too. If a ready market exists for that exact clip use, using it without permission weighs against you. This is why parody or criticism of the work itself is often safer than repackaging it.

Key takeaways

• Transform your clip with new purpose or meaning.
• Respect creative works by using only what you need.
• Avoid using the heart of the original.
• Do not substitute for the source or its licensing market.
• Weigh all four factors against each other.
