Copyright law does vary between countries, so it's important to consider the specific copyright laws in your jurisdiction. However, in general, using a YouTube video clip in a research presentation would require the permission of the original creator, as it falls under the category of reproduction and distribution of copyrighted material. Simply including the clip in your presentation without permission could potentially be a violation of copyright law.

The concept of "fair use" is typically found in US copyright law and allows limited use of copyrighted material for specific purposes such as criticism, commentary, or education. It's important to note that fair use is a complex legal concept and it is subjective, meaning courts determine if a specific use qualifies as fair. Fair use may not apply in other jurisdictions or in the case of using an entire video clip without transformative or critical elements.

To ensure compliance with copyright law, it is generally recommended to contact the original creator and ask for permission to use the clip in your research presentation. This can involve reaching out to the creator directly or using licenses or platforms that allow legal use of copyrighted material. In some cases, you may also need to pay compensation or obtain a license to use the copyrighted material.

To summarize, it is important to understand the copyright laws in your jurisdiction and obtain permission from the original creator to use a YouTube video clip as part of your research presentation.
