Hi Bala, I think the easiest way is simply to zoom in so that the graphics window is the same as what you want in your movie. You can use "savepos" and "reset" commands to save and restore different views. Window dimensions can be set with the "windowsize" command. I don't know of any way to do exactly what you are asking. One could save all the larger image frames, then apply a processing step to crop to the smaller area that you want from each image file, then do a separate movie encoding step on the set of smaller images. However, this can't all be done inside of Chimera (you would have to use some other program or script) and it sounds much, much harder to me than simply setting the view to what you want in the first place.
