GIF is like a digital flip book. It consists of two or more repeat of the same image or action transition, looping in multiple or endless cycles. There is no audio in a GIF file. Video is a live action/motion film with its natural and added audio effect. On the contrary, slideshows are made up mostly of still frames such as photographs. By nature it does not have an audio but audio such as music can be added. Know the difference before purchasing the service. Thank you!
