== Technical background ==
The human eye can perceive between 10 and 12 pictures in a second. Modern TV shows 24 pictures per second. This gives the impression of video. This is called Frames Per Second or FPS. https://en.wikipedia.org/wiki/Frame_rate
If you were to store 24 pictures, for every second, that would make videos exceptionally large. Instead, they record 1 picture and then store the data of what changes between frames. So if there's very little movement, very little extra data needs to be stored. This can make videos a lot smaller in size. Animation uses this capability. https://www.youtube.com/watch?v=X1TAdd9Vm7s
The instructions of HOW to store the differences is called Encoding. You also need instructions on how to draw the differences called Decoding. Collectively a set of instructions is called a Codec (Coding - Decoding). https://www.youtube.com/watch?v=_nPsBwMivCk
There are many many codecs available. https://en.wikipedia.org/wiki/List_of_codecs#Video_compression_formats
International standards are working towards a simple universal standard for video. MP3 became an international standard for Audio. MP4 is becoming the international standard for video. Whilst not all that new (it came out in 2001 and was heavily revised in 2003), its adoption has not been as widely accepted as other video formats. https://en.wikipedia.org/wiki/MPEG-4_Part_14
With the advent of modern browsers playing video, MP4 is fast becoming the codec of choice.
MP4 videos going forward will be the video format playable in all browsers, but if you are trying to play video in older browsers FLASH video is still the way to go.
== Start ==
= Converting = Conversion Software ==
First you need your MP4 video to convert. Put it somewhere handy on the desktop. This process also facilitates numerous file converstionsconversions.
As you install that software, please just watch out for the extra tool bars and optimisation software that you don't need. You can decline them, but please be careful.

== Further support ==
If you do need a hand going through this tool and how it works, we can indeed help. We may need remote access to your machine to get you going, which would involve using TeamViewer or similar tool to remote control your machine.
