HIGH DEFINITION VIDEO PRODUCTION
Hi Def or simply HD, is mentioned on many new TV's, but what does it mean?
Over the years our TV/video hardware has enabled us to see ever improving picture quality.
Currently we have a resolution of 720 * 576 pixels (both widescreen 16/9 and traditional 4/3).
This is known as 'Standard Definition' or 'SD'.

HD enables a resolution up to 1440 * 1080 - nearly 4 times better.

This example is not full scale - but shows relative sizes.

Like all new technologies, it takes time to be integrated with the consumer market.
HD TV's are already available in the UK, however HD sources are sparse, but include:

  • A very few satellite stations
  • HD camcorders - should you be fortunate enough to have one.
Are there HD DVD Players?
High Definition video cannot be accommodated on DVD's as they stand - so we have a new technology to enjoy this exciting new medium in full.
The technology is ever-changing and Blu-Ray has now seen off Toshiba's HD DVD rival (akin to the end of the VHS versus Betamax battle).

Current advantages of High Definition video
Shortage of HD sources doesn't mean we can't take advantage of tomorrows technology today.
  1. If a production is done in 'HD' the higher resolution may be seen on an increasing number of HD TV channels.
  2. Most cameras record in traditional 4/3 ratio.
    For widescreen usage, many cameras effectively record black 'letterbox' bars top and bottom of the picture. This amounts to throwing away a large percentage of the possible quality.
    By filming in HDV and down-converting to widecreen at Standard Definition, the quality is far superior.
  3. Anything you record now may filmed in HD, even though perhaps used in SD for compatibility with the current consumer market. In a few years time - when the infrastructure catches up - the HD camera footage can be re-visited and re-produce it using the latest technology. This may be done merely to replace your existing 'Standard Definition' production or alternatively used as part of your reference library for future new productions.

Does Aztec film in 'High Definition' Video?
In short, yes - but not always. It is Aztec's policy to offer the highest quality for each clients needs. There are a number of factors that determine the best camera format. For example:
  • Whether the production is to be widescreen (16/9) or 4/3
  • The delivery medium for the project (e.g. TV, DVD, PC, Web, Videophone).
Aztec includes High Definition cameras in its Arsenal.

Our producer, David Smith, has 23 years Video experience (behind the camera and post-production) and even more years of business experience.

Upon contact he can advise on the different methodologies and which is best for your project.
