Update the way movies are generated. Please refer to the examples. 

The user can now either specify the image range(first and last images inclusive):
mov.imageRange(input_directory = PYVISI_EXAMPLE_IMAGES_PATH,
        first_image = IMAGE_NAME + "000938.jpg",
		last_image = IMAGE_NAME + "000948.jpg")
mov.makeMovie(os.path.join(PYVISI_EXAMPLE_IMAGES_PATH, "movie.mpg"))

or the user can specify a list of images:

lst = ['image1.jpg', 'image5.jpg', 'image7.jpg]
mov.imageList(input_directory = PYVISI_EXAMPLE_IMAGES_PATH, image_list = lst)
mov.makeMovie(os.path.join(PYVISI_EXAMPLE_IMAGES_PATH, "movie.mpg"))
