As explained above, one can easily create an animatic using the panels from the storyboard that is created.

Place the images sequentially and time them properly. Once the images are in place you can run (play) them once to check if the shots are connecting together to convey the story properly or not.

Sound and Music is also one of the most important aspect of an animatic. One can create a scratch/rough sound using the process of audition. This means you create all the necessary sounds like dialogue, Foley sounds, FX sounds with your own mouth. And then add a rough suitable music with it and edit it precisely with images. For me this process comes in very handy and its makes the animatic creation easier.

You can keep on playing with the animatic till the timing is right and you are satisfied with the pacing of the shots. Since animation is an expensive process its better the decisions or the necessary changes are done at the animatic stage itself.
