Definition and spelling of TV- Formats by the EBU.

TV Formats

There are multiple different frame sizes and frame rates for the production of Television globally. Since the migration from standard definition to high definition production – and now with UHD production taking off, it’s important to understand what format you are delivering to – as well as recording.

The EBU use a common approach to describing the type of format you are recording or delivering. This is based on the format of the picture. The description is based on the vertical resolution of the picture (the active number of lines displayed), followed by the sample format (interlaced-i or progressive-p ). After a slash, the frame rate is then displayed. Throughout this app we will always refer to this approach – for example 1080i/25
Below are descriptions of some of the different SD and HD Formats:

576i / 25
