Display & Content Formats

Previous page Return to chapter overview Next page

Since the invention of film and the area of black & white as well as colour TV, a lot of image formats have been around and are still in use. Three different fields have their specific image formats:

Film

8mm, 16mm, 35mm, IMAX

Television

SD: PAL, PAL+, NTSC

 

HD: 720i/p, 1080i/p

Digital Displays

VGA, SVGA, XGA, SXGA, SXGA+, QXGA, 4k

Aspect ratio

All these different image formats have different aspect ratios. The aspect ratio describes the relationship of the image's width and height. A very common aspect ratio used by standard TVs and computer monitors is a 4:3 ratio.
Another - very common - aspect ratio is 1:1,85 which is used for widescreen cinema projection.
In HD digital projection the common aspect ratio is 16:9.

The aspect ratio is a very important figure to consider during content production. Wrong settings lead to distortions in your images, e.g a circle may not look round anymore. In Pandoras Box, you have the following possibilities to influence the aspect ratio of an image:
- Layer Inspector
- X and Y scaling
- for more advanced users, the Camera settings might be of interest.

Resolution

It is also useful to know the resolution differences between film, television and digital displays. Film is an analog way of recording and projecting images, while TV and digital displays have specific resolutions.
When film is transferred to a digital medium, it has to be scanned at a specific resolution; 2K and 4K are common. At this point, it is important to say that the resolutions are superior to High Definition TV.

TV is available through different standards today. The formats PAL and NTSC are called SD: Standard Definition. High Definition is an independent format and is subdivided into progressive scan and interlaced image. Since most digital devices are optimized for progressive scan, this is important for digital projection and digital lighting. High definition is known in two common standards 720i/p (1280x720pixel) and 1080i/p (1920x1080pixel).
In Pandoras Box, the setting "Deinterlacing" can be found in the content's Inspector tab.

Digital displays support multiple resolutions that reach from VGA (640x480pixel) to QXGA (2048x1536pixel).
In the past the most common resolution for digital projectors was XGA (1024x768pixel). Today HD formats are widely used by high profile video projectors on the market.

The next topics give suggestions how to define your content resolution, provide an output resolution table and explain in detail different content formats, such as audio, single images, image sequences and videos.
