As far as I know it´s not possible to add a hyperlink with shotcut alone. So do you know any solution to this? Maybe a suitable software which creates a hyperlink and the file can be easily openend with shotcut?
Ok, I didnt know that I could play the video other than on youtube so I didnt notice, but I think you are saying that the button is a youtube-only feature (which is surprising to me as far as I only know Youtube subscribe buttons that can be shown at the end of the video as end credits)
But in general: Does someone know how to add a hyperlink to a URL using shotcut (and maybe another software)?
Video, images, and text do not inherently support links. They are simply data. It is the world wide web, HTML, hypertext, and web browsers that add the concept of a link (more specifically hyperlink). Most video editors do not output HTML (a web page) for you that could include a video with links. Even if it did, it is not trivial to put this hypothetical output on a web server and expect thousands of different kinds of devices across numerous different levels of networks to be able to handle it well. That is, in part, why things like YouTube, Facebook, and Instagram have flourished.
