Animation formats.
.Flash
.Shockwave
.QuickTime
.Dynamic HTML
.GIFS
Good points
Flash-This format of animation is common used in many webpages which make them better to operate with. Flash enables the user to open websites faster as this form of animation is based on a vector output therefore meaning images are smaller size but with a high picture aspect ration this means that when you zoom in on an image the picture will not blur or pixilate this form of animation is good for photography.
Bad points
Flash is incompatible with some older devices, or even blocked on some portable devices or by browser plugins.
Flash files are scripted code, that means that anything can be scripted into a flash file, this means if an attacker were to code a infection into the flash file which your computer automatically downloads you could get infected from this if you have no antivirus or have not updated it.
Good points
QuickTime- This form of animation has been developed by Apple. Apple designed this form of animation to run on an algorithm base therefore this form of animation is simple and yet effective. The algorithm base on this animation simply encodes and compresses files so that they can be used in Apple QuickTime Files.
Bad points
Shock wave is very good as it has the ability to open other file formats so you can load a flash file into shockwave but this is not backwards compatible as flash will not read this file type.
Quicktime is better than DHTML because it displays more fluent animations that have moving parts like a character walking users may experience lag, but with DHTML the image may not be able to walk, which is bad but the process is allot smaller and no lag will occur but to code these you need to be a expert in Javascript and HTML.
Good Points
Shockwave- This form of animation takes longer to load than flash but is better to create more complicated animation such as games. Shockwave is more durable this meaning that you can load more files of different format into it so as an example you can load a flash file into shockwave whilst on the other hand it does not work loading shockwave into flash.
Bad points
Shockwave is not compatible with other programs like loading a shockwave file into flash programs.
The main problems are that the users need to install plugins to get this to function. Active-X controls this plugin is required.

Bad points
Requires videos to be streamed from a server to the user, they have a lower quality than other more modern formats such as flash.
Good points
Dynamic HTML- This form of animation isn't as good because it will not display moving images such as a person with walking and the legs move with DHTML it would be a still image moving across the screen but it would be more fluent and would not have any lag.

Bad points
The software required to use dynamic HTML can be very expensive and not all internet browsers support it. The tools to edit the format are very costly. Long and complex coding and only expert in JavaScript and HTML can write and edit them.
Good points
GIFS
Loss less compression this means that when you compress the image the quality is not affected.
Loss less compression this means that when you compress the image the quality is not affected.
Relatively
small file sizes, this is better for storing gifs on websites that way led
storage is taken up.
Supports
the use of transparent back grounds this is good for websites so you don’t get
big black boxes around the images.
Suitable
for inclusion on websites because the images Are compressed and when you
connect to the site it will take less loading time.
Maximum
pallet of colours is only 256 colours this is bad because you are limited
The
colours appear blocky and unsightly this is bad because it is an eye soar to
look at
Dithering
when it is used the image can only be compressed to a certain ratio this is bad
as you cannot make the size you want
Summary
Each format has its own strengths and ability's, main strengths of flash is that it will enable the user to load up websites allot faster compared to shockwave you would be waiting allot longer.Shock wave is very good as it has the ability to open other file formats so you can load a flash file into shockwave but this is not backwards compatible as flash will not read this file type.
Quicktime is better than DHTML because it displays more fluent animations that have moving parts like a character walking users may experience lag, but with DHTML the image may not be able to walk, which is bad but the process is allot smaller and no lag will occur but to code these you need to be a expert in Javascript and HTML.
