If you don't have a script, it means you don't have it in your movie. Without a script, you wouldn't start a movie by saying that I will start a movie and then I will draw as soon as I can think of it. A scenario with a fully composed introduction, development, and conclusion sections constitutes the first stage of all animation types. The scenario can be 1-2 pages even for a short animated film, or it can contain 50 - 60 pages of information. This may vary depending on the subject of the movie you want to do. You must be wondering if there are any video animation services. If you wish to find one, just start searching on the internet and you will find one for sure. What do you think?
