(motion Picture Experts Group)On some cameras you have the ability to record extended bursts of movie usually around 20 seconds of 320 x 240 pixel footage at any given time (though it varies from model to model). The idea for this footage is that it can be e-mailed to people as an attachment (as compression is quite high) or put onto a web site. Generally it is only the higher priced digital cameras that feature this mode but it is becoming a standard feature on all cameras as the internet grows.
