Scene resolution

My game has 1280x720 resolution, i want to create a scene where when talking with a char, the main char looks down looking for weapons, the animations of the other char is 1280x862, so it gives me 142 pixels to look down, what is the best way to achieve this?

-Change resolution?

-Move the char wont work because i suppose it woud use walking animations, and i want it while he talks.

-Move the object where the char is standing?

-Create a scene with another resolution, if thats possible?

-Any other easier way?

Also, can i do the same thing but instead of moving automattically looking down, move it with the mouse, as if it was the camera, or maybe scrolling the scene when the mouse reaches the limit?

What would be the best way to achieve this?

Thanks a lot
