So I know this is a pretty novice question but I was curious about posting fan made trailers on my own personal website/portfolio and if it is even legal or not. For the most part I am a freelance 3D Artist but recently have been thinking about working on my video editing skills and having a separate tab on my website to showcase some some work in video editing.
I know this website is advertised as film and editing for fun, but I figured a few people might know the answer I'm looking for. So is it legal to make fan made trailers of movies/video games and put them on your website to demonstrate skills as a video editor? I've been looking into it, and I think the answer may be leaning on no, but I'm not sure. Obviously I would have a disclaimer at the end explaining my part as only video editing and everything else is is copyrighted by the appropriate owners of the material.
Also, if it is legal is this something that would be looked down upon with employers? If so I'm just kind of wondering how people started building up portfolio work if they are in this industry. Do they just film and edit their own videos from small personal projects, or is is alright for them to use other resources not of your own work, but just to showcase your skill within the craft.
