I cannot find the post but is there any reason why a clip from BBC Redux cannot be played out on air? Is it just because its not high quality enough bit rate wise (doesn't news require a minimum of 35 Mb/s)?
I am asking because I would think something that is HD or SD quality on air would be good to re air - especially if it hasn't been transcoded (someone said the transport stream was recorded).
It could be of absolutely necessary but I think the policy is that it shouldn't be. There would back a quality drop as it's been mpeg encoded already and will go through the process again. But then the news regularly uses poor quality clips off YouTube rather than Redux or the BBCs own archive so I don't think anyone really worries about it.
I think it's more of a problem on radio. Using clips from the ROT system or off air from DAB is a no-no as the extra encoding can add nasty artefacts. Think of a 64kbps mp2 clip being re-encoded into a 128kbps DAB stream.
But then as you say when off air clips of other broadcasters are shown on air, in fact its compulsory as part of the sports rights rules for clips of sport where you aren't the rights holder to take them off air. So you'll see clips of a football match from Sky Sport
The other reason, for the News Channel at least, is because everything will have a ticker and clock on it.
Incidently the standards for BBC programmes can be quite high. For example when they started HD a programme could only be considered HD if there was a certain % of HD native material. And what constituted HD material was quite strict, footage from HDV wasn't for example, nor was HDCAM, as only HDCAM SR recorded to a high enough quality.
