How to make people disappear

[gaspargg]

Hello, i making a football video and i've got that piece of footage that last 43 frames :


footage it self : https://youtu.be/4NMIWvlgL7E

and during these 43 frames i want to get rid of all the player exept the guy in the red circle that has the ball ( make them disappear )

I've tried to duplicate that layer freeze frame it and cute pieces out of it with the mask tool to put them on top of the clip, but it doesn't work ( i did track the footage and apply it to the pieces ). the probleme is that the camera that took this video moves in a weird way.



So if any one has an idea of how i could do that it would be very nice of you



PS : if you got time to waste could you do it for me please ?



thanks a lot for your time and your answers and please excuse my bad english ( i'm french that's why )
