I am the author of an accepted and published manuscript in a peer-reviewed subscription access article. Accompanying this manuscript are some videos I created. I would like to upload these videos to a third party website and want to know if this is allowed. I have read the author rights, but my use doesn't exactly fit into the wording so I'm not so sure what the answer is.
More specifically my article is in 2D Materials of IOP and I want to upload some videos that form part of the additional multimedia to YouTube so that I can create an interactive poster where people can view videos related to content on the poster.
I have emailed the IOP concerning this matter so I can provide an answer to at least my specific case, but I thought others might have something interesting to say on this matter, e.g. perhaps the intended use means it automatically is "fair use" and is acceptable for all journals.
