• Animated GIF files


• MPEG files


• Shockwave files

In your notes refer to what they are used for, their colour depth and file size characteristics

GIF FILE

A GIF sometimes pronounced jiff means , GRAPHICS INTERCHANGE FORMAT. This file format is generally what is used all across the internet. GIF supports many different colours and image resolutions.

JPEG FILE

It compresses images, and it only chooses the pixels that can be seen by the human eye to ensure that space is not wasted.At a moderate compression level it makes it harder for the eye to notice the difference between the slight details.

ANIMATED GIF

animated gif is a series of gif images played one after the other. It can look very realistic with enough frames to create it. This format takes up plenty of space.

MPEG

attempts to remove frames that are repeated in a compressed video. It is able of putting on sound tracks on which animated GIF's cannot do and had more frames - file sizes are much larger.
