Can I List Myself As The Editor Of An EditStock Project?

Yes, on your version of the cut you can add text that says "edited by" and your name. On your resume, portfolio, personal website, and demo reel, listing yourself as the editor of an EditStock project is exactly what you're supposed to do. 

However, you cannot credit yourself on places like IMDB or submit your cut to a film festival. You should also not credit the original filmmakers including the actors, director or original editor. 

Where you can credit yourself

On your demo reel or website it's perfectly ok to say that you edited the project the viewer is watching. You should include text that says "footage provided by EditStock" if you are showing a complete cut of the film. If you are showing a montage style demo reel that you don't need the credit logo. All of that is completely normal and expected.  

Where you can't credit yourself

You cannot list the project on IMDb as an official credit. You cannot put it on a film-credit database or any service that treats credits as official employment or production history. You cannot submit the cut to a film festival under your name as the editor, because that implies the cut is an official version of the film eligible for theatrical or competitive screening.

Those restrictions exist because they cross a line from "I made a practice cut from borrowed footage" into "I'm claiming this is the official version of the film." That's a different thing entirely.

The distinction

The reason the restriction exists is because whatever version you make - for better or worse - was not approved by the filmmakers. IMDb credits and film festival submissions are meant for work you did in a professional capacity—you were hired to edit something, or you made an original film. EditStock projects are learning work. They're practice. They belong on your reel and in your portfolio because they show what you can do, but they don't belong in official credit databases.

It's the same distinction an editor makes when they cut a test scene for a job interview. That test scene goes on the reel and in the portfolio. It doesn't go on IMDb or in a festival submission.

List yourself as the editor everywhere that makes sense—your resume, website, reel, portfolio. You earned that credit. Just don't submit it as official production history.
