Unit 31 P3 The theory of Persistence of vision.

The theory of Persistence of vision.

Task 4, P3 - Discuss the advantages and limitations of animated GIFs
Produce an entry in your blog that discusses the different animation formats and tools available in the animation industry. You should also discuss the features, advantages and limitations of animated GIFs. To do this, you need to create a list of the "pros and cons" of the format and discuss these. What would each "pro" enable you to do, in terms of producing your short animation? For each negative point, what it will prevent (or restrict) you from doing?

In this post i am going to be speaking about the different types off animation, the format and the tools that you use to make them. I am also going to be explaining the advantages and disadvantages off using animation and where its used.

Firstly i am going to be speaking about the advantages and disadvantages of animation, There is quite a few advantages if you use animation wisely but if don't do it right it can make your website look shocking! if you are using animation on a website you need to avoid using it as much as possible because one or two animations on a website enhances the websites look and makes it look better but if you have more than 3 it can start to look a mess. for example if you look at www.lingscars.com it is full of pointless animation that moves you away from the website and the point its trying to make. the main advantage of using a little bit of animation is that to the person viewing the web page its eye catching and hooks them into reading the content.

The first type of animated image i am going to talk about is GIFs this is a bitmap format that is used a lot on the web. The advantages off GIFs is that the file size is very small this means that the animations will load quicker. You also don't have to download any any plugins or anything because the browser already supports GIFs. On the other hand the disadvantages of GIFs is that there is a limitation on file size as well on a limitation on colours that can be used in the animation. There is also no sound with GIFs and the worst disadvantage is that it could display differently on all platforms.


Flash is a very well know animation animation that unlike animated GIFs flash can have sound with the animation. The animation works on its own with a plugin but statistics say over 90% of computers already have a plugin installed to play flash this means that not even 1 in 10 people would have to download the plugin to watch it. Another advantage if you don't put to much animation on it makes the website just right it adds like a finishing touch if there only 1 or two animations. Whereas on the other hand flash can take a long time to load because the files are quite big. Some people don't like flash at all because to them it is very annoying so they will try to avoid websites with a lot of flash as much as they can.


Shockwave is focused on 3D animation and streaming videos and also has fast rendering engine then flash. The disadvantage for Shockwave is you have to download extra software for shockwave to play which is bad because not that many people already have the software installed.

Dynamic HTML is the old way for web animation, this is not a language or a plugin it is a combination of HTML 4.0 JavaScript CSS and DOM. The file sizes are very small and doesn't need any external software because it is using languages supported by the most browsers. The main Disadvantage of dHTML is that it displays different on different browsers because it is not one language its a mix so it could display completely different in some browsers then what you wanted it to look like.

There are a lot of types of animation and different tools firstly there's the industrial spec programs called adobe flash player this is a very expensive program but is very good for making animated images.
