The use of copyrighted music in social media posts, including Instagram videos, is subject to the policies and guidelines set forth by the respective platforms and the copyright owners of the musical works. The maximum length of time that copyrighted music may be included in an Instagram video post is therefore determined by these factors.
According to the "Music Guidelines" provided by Instagram, users are prohibited from using copyrighted music in their posts unless they have obtained the necessary rights or permission from the copyright owners. If a video is found to contain unauthorized use of copyrighted music, it may be removed by Instagram.
It is also worth noting that copyright owners, such as music publishers and record labels, may choose to enforce their rights through various means, including the use of automated detection tools that can identify instances of copyright infringement.
In terms of the length of time that copyrighted music may be used in an Instagram video, there is no set duration established by the platform or by copyright law. The determination of whether the use of copyrighted music in a video is considered a fair use, and therefore exempt from infringement liability, depends on a number of factors, including the purpose and character of the use, the nature of the copyrighted work, the amount and substantiality of the portion used, and the effect of the use on the potential market for or value of the copyrighted work.
In practice, many content creators choose to limit the use of copyrighted music in their posts to brief snippets or brief background accompaniments, in order to minimize the risk of infringement. Additionally, some platforms, including Instagram, offer the option to use licensed music through partnerships with music rights organizations.
In conclusion, the maximum length of time that copyrighted music may be added to an Instagram video post is not specified by the platform or by law, and is instead subject to a case-by-case analysis of the specific circumstances of the use. It is recommended that users obtain the necessary rights or permission from the copyright owners, or limit their use of copyrighted music to brief snippets to minimize the risk of infringement.
