UK HD TV: Interlace not dead yet

Wednesday, 09 July 2014

From October 1 2014, nearly all UK broadcasters will only accept TV programmes as files - tapes will not be allowed. To help independent TV production companies prepare for 'File Delivery Day,' the UK Digital Production Partnership have agreed on standards for everyone to follow.

The Digital Production Partnership is "funded and led by the BBC, ITV and Channel 4 with representation from Sky, Channel 5, S4/C, UKTV and BT Sport to help producers and broadcasters maximise the potential of digital production."

As well as a guide for producers, there is a full technical specification for post production workflow as well as a minimum metadata set.

An important aspect of the technical standard is for those who like to use animated graphics, transitions, titles and credits scrollers: they must be rendered as interlaced. Even if all the video in a programme is 25 frames per second progressive…

moving graphics and effects […] must be generated and added as interlaced to prevent unacceptable judder.

To see YouTube attempt to show the interlaced fields, use the settings control (the cog) to choose 1080p (HD) and then click the full screen button in the bottom-right corner of the player.

In Final Cut Pro X, make sure your projects are 1080i25 and to check that graphics and transitions are properly interlaced, use the 'Show Both Fields' option in the Viewer's pop-up menu.

The UK TV file format specification:

Each high definition programme must be delivered as a single MXF OP1a file which conforms to the AMWA specification AS-11 v1.1. The AS-11 file must use the ‘UK DPP shim specifications’ that describe exactly how the file must be constructed to meet DPP requirements

Final Cut Pro X users will have to turn to third parties to handle the video encoding and required metadata. Currently the only product that is available is Hamburg Media's AS-11 Suite

The rest of the specifications (including the standard allocation of 16 audio tracks), read the Digital Production Partnership Technical Delievery Standards document.

 

The demo video features footage from EditStock, a website that hosts rushes from short films you can use to practice the craft of editing, and my free Leaves title plugin for Final Cut Pro X.

 

 

Mark Harrison, BBC: “We are taking 4K very seriously”

He says TV hardware manufacturers are

inviting consumers to consider seeing their television as less of a television and more as a primary display. It’s almost like the TV becoming the biggest and best computer screen in the house. Once you have accepted a ‘television’ is actually a display – and the discipline of television is separated from the device – it has subtle but profound implications for both consumer and producer.
