Question

Remove one person from a video clip, from a background full of dancing people

Is it possible to use content-aware fill in after effects, to remove one person in the foreground of a video clip, with lots of people dancing behind them?  Ive read that this feature only works with very unbusy basic backgrounds.  The video was filmed in slow-mo.  Has anyone ever managed it and how?

    Content-Aware Fill requires one object that moves across a background that does not change. A drone shot of a car driving down a highway works because there are frames before and after the car passes mile post 25 that do not have the car at mile post 25. 

     

    If you have a moving camera, a moving crowd of people, and you want to remove one person, you need some frames before and after the person moves in the frame that have the other people in in the same position they were in before or after the person that was moving got there. That's asking a lot from any kind artificial intelligence. The likelihood of it working automatically is astronomical.

      It's impossible to make an educated comment without seeing the footage, or at least a still from the footage.  But what you've read is generally true - Content Aware Fill is quite good at replacing static and slow moving content, but can struggle when there is a lot of movement/change.

       

      It's quite a straightforward process, so your best bet is to just give it a try.

        here's a screen shot, cant seem to upload clip ... The guy in the centre, needs to removed bc he gatecrashed the event, was a pretty wasted and was wearing a labelled top, but its a great slow mo shot, so wanted to use if at all possible. Thanks for advice, Im managing to make mask, track it, but it seems the background gets messed up.  Also, I cant seem to export the final results.

        Unfortunately the scene looks too complex for CAF to be effective.  I did a CAF on your single frame and it's obviously a bit of a mess.

         

         

        But you could potentially save the shot by getting creative.  If you can use it in your edit as a background for a title, or something, you can draw the viewer's eye away from the problem area.  Just a thought, without knowing what your footage is really like.
