Animated GIF

What is an Animated GIF?

An animated GIF (Graphics Interchange Format) is basically just an images which can be animated by adding a number of different frames to it each showing the image in a different position. GIF animation isn't designed to give the same amount of control and other animation formats, however, it is very popular as pretty much all web browsers use them.

Animated GIF's are designed to be a lot smaller of a file than other animation files like Java scrips, this is because they're not designed to be incredibly detailed, they're designed to be simple and short.

GIF's are used on the internet for webpages, an example of this would be when you go onto a website and see an image moving, this is what's called a GIF, it is basically just a sequence of frames put together to make an image move.

An animated GIF is its own little file, it is a single file with a number of images set out in a specific order so that when the images is played to move, the animation in it is fluent, depending on how many frames (images) you put in the sequence is what will determine the outcome of the GIF (if the images moves fluently or if it is jumpy).

Animated GIF's are designed to continuously repeat themselves, they're on a never ending loop, however, you can design GIF's to go through the sequence once or a few times and it finishes.

Animated GIF's are commonly used on websites, such as them being an animated banner at the top of the page with the page title on them, these are commonly at the top of the page on a continuous loop going from one side of the page to the other and back.

Animated GIF's are actually fairly easy to create compared to Java and Flash animations, this is because the file is a lot smaller and doesn't have to contain as many frames.

Animated GIF's actually only have a small amount of colours that are able to be used, only 256 colours are available so that the colours on the GIF's are easy to see and don't blend with each other.


Using GIF's is actually a good way for you to create a website which will look a lot better than it would without a GIF's, depending on how good the GIF's is, is what will determine on how pix-elated it will be when it is finished or zoomed in/out from.

Even though using a GIF can make a website look better, if you use too many of them then the website won't look as well and work as effective as you had hoped, this is because they would take over the main activity on the website and be a big distraction to the website viewer.

GIF's are actually designed to support a background where you can still see what is behind it; this is so that they don't cover any vital information that may be on the website. Because GIF's attract the younger audience, the websites that contain them have a lot more viewers as it is mainly the younger generation that would be using them.

Another good thing about GIF's is the fact that the file size of them is actually really small, this is an advantages because it means that they don't take up as much room on the system/website as most other images/animations that may have been saved.

Disadvantages

The disadvantages of GIF's are basically the fact that it is difficult to keep the size of the file small so that you can use more of them (save them), for this reason it's a lot more difficult to upload them onto your website or they may not load correctly and function how they are meant too.

GIF's are only able to contain a limited amount of colours on each, you are also only able to choose from 256 colours, any other colour that you have chosen which isn't recognised won't be displayed on the GIF that you have created.

You're not able to add large amounts of sound in with your GIF's unless you add it into the background on something such as a YouTube video. GIF's are designed to move, they are just an image which can move and display different images on a single screen, they're not able to contain a large sound type, it can only be a small sound file inserted in with it.

Formats

There are a wide range of different format types for animated GIF's, such as Flash animation, which is commonly used throughout IT industries for creating moving images, it tends to be used a lot in areas of teaching so that the IT students can learn about the basics of creating GIF's.

Shockwave animation is basically what enables you to use a range of different multimedia players, such as creating GIF files, sound files etc. Shockwave is what enables you to play the games that you find on the internet, which are all just animations put into a big sequence. It isn't only gaming websites which use Shockwave files, sales websites and advertisement websites also use them.

Quicktime animation files are basically allow you to link up your GIF's to sound files so that you have an animation and also sound behind it. To use quicktime you have to use the internet so you can download the correct files onto the system to add with your GIF's so the file is the correct size.

Dynamic HTML animation files are basically what allow you to add annotations (text files) to your GIF's, this is so that you can make the GIF look like it is talking (if it is an animal or human etc.). Dynamic HTML files are what makes the GIF interactive, basically meaning that in order for the GIF to proceed onto the next stage of it you must control something that is going on with it (it may be a tiny game created through GIF animation, this is commonly used on certain events on GOOGLE).
