Resolution: Resolution is measured in pixels. As an example 1080p is 1920 pixels across and 1080 pixels down. The more pixels you have the cleaner the image will appear.
A lower resolution will look blocky when scaled up on a bigger display. Most cameras today will record in 1080p but 4K is quickly becoming the standard.
The P in 1080p refers to progressive scan. When an image is rendered on a screen it can either be interlaced or progressive scan. Progressive means that the pixels of the image or video frame are rendered at once. Interlaced is when one frame is rendered in one set of lines and the next frame is rendered in another. This creates a strange vertical blinds effect on our progressive monitors. Interlaced is normally used in the USA so we tend not to use it.

A codec is a device/program that compresses data such as video footage to allow it to be easily transferred from location to location such as moving it around in files or in a video editing software program. It can also decompress received data so it can show it in its original state.

(Same group as Fiona Cowie ;P)
Here is some facts:
-Involves encoding information using fewer bits than the original representation. Meaning you are decreasing the size of the original file while still keeping the same image as it was before
-Same file just needs less space

The aspect ratio of an image is the relationship between its width and height. It is usually separated by a colon, for example 16:9.
Nearly all TVs and monitors are viewed in a aspect ratio of 16:9 as this is the best ratio to view HD TV shows. However movies are filmed in a ratio of 21:9, when viewed through a TV this results in black bars on the top and bottom of the screen.
