Video help!

Hey,

Does anyone know how to put a video of a person infront of a still image made on the computer but making sure its only the person there. Much like using a green screen but i dont have access to one, so does anyone know any crazy editing skills to do this? If so, could you please specify and tell me which program to use. Aswell as this, does anyone know how to make cool animations but looking realistic, so not cartoony.

Thanks.

 

That's major editing, it won't really be possible with anyone around here's graphic skills.
I'd try professional tutorials or something along that line.
Also, a green screen is really the only way to achieve the effect that I think you're going for:/.

 

solid color wall or sheet is your best option

 

This, but it's still probably not going to give you the look that you're going for:/
