Chetna, when you load your trajectory in VMD, move the graphical display to your desired pose and select Toggle Fixed. You may just click F written in front of the trajectory and your protein is fixed. In representations, go to trajectory tab where you can play around with values to smooth the video, the default is set to zero. Increasing to 6 or 8 smoothes the videos in my systems and might vary in yours - just play around with it.
Go through the VMD tutorial, it provides dumb easy instructions to follow.
Best,
Raman

Subject: Re: [AMBER] how to create nice animated videos to show simulations
You will probably get more help on the VMD email list, or looking at their
tutorials. A good start is to learn the rmsd trajectory tool that will keep
your peptide centered. You can also do that using cpptraj in Amber, but for
videos it might just be easier to do it all in VMD.
