If you are suplying Fonix with media, please note the following preferred requirements:

 

  • Widescreen (16:9)
  • SD (Standard Definition) of 720 x 576,
  • but preferably HD 1280 x 720
  • or 1920 x 1080
  • Quicktime (Mov) or MPEG2 or AVI using a H264 or Avid Codec

 

(We will accept any format and endeavour to use it. We do have a vast array of software conversion programmes and equipment to allow us to succeed, and a lot of experience in this area. We rarely come across a file we cant handle, but in the event, we will let you know as soon as possible so that you can hopefully send us another format.)

 

Brief explanation of the requirements

 
Widescreen = The same shape as new plasma TV’s

 

SD = Before High Definition, SD was the standard definition and much of TV is still broadcast in this format.

 

HD = High Definition, 4 times more detailed and therefore clearer and better image quality

 

720 x 576 & 1280 x 720 & 1920 x 1080 = The number of pixels (dots that make up the image) along x down that make up the picture. The higher the numbers, the better the picture resolution.

 

Quicktime (Mov), MPEG2, AVI etc. Theses are the file formats that the video is transported in, requiring a specific player to play back, and created by various bodies and companies.

 

H264 = Codec. This is the (most commonly used) form of compression used to make the video file small enough to be transported across devices and the internet.

A Little More Detail

 
Resolutions and aspect ratios are very important when considering to display a presentation or video on some form of electronic device.

 

Resolution determines the sharpness and clarity of the picture on your screen. It is measured in the number of horizontal pixels multiplied by the number of vertical pixels, the higher the number of pixels the better.

 

The aspect ratio of an image is the ratio of the width of the image to its height, expressed as two numbers separated by a colon e.g. 4:3.

 

There are many aspect ratios in use in various media-related applications, in the television industry there are two common aspect ratios, 4:3 and 16:9.

 

4:3 refers to the aging standard definition format that is no longer used by broadcasters, it has been superseded by the 16:9 widescreen format, this is used for both standard and high definition video.

 

Although there are many different resolutions to choose from, here is a list of the most popular resolutions (and respective aspect ratio) used today:

 

720 x 576 (16:9) – The resolution of standard definition widescreen video.
1024 x 768 (4:3) – The default resolution of a Microsoft PowerPoint presentation.
1366 x 768 (16:9) – The typical native resolution of a “HD Ready” Plasma / LCD.
1280 x 720 (16:9) – This is the High definition standard commonly known as 720p.
1280 x 800 (16:10) – A popular resolution found in widescreen laptops.
1920 x 1080 (16:9) – This is the High definition standard, referred to as 1080i/1080p.

 

This graph contains an accurate representation of many of the common resolutions in use today.
