Which Format should a content provider really use

[Rhoel]

I work for a small video content provider and we are now faced with the dilemma of which format to output our (CGI) films in. We have to produce content for TV and mobile phones too, so we future proof output wherever possible.

Unforunately, TV companies have provided us with conflicting foramat demands, 720/1080i etc.

So I pose the general question here: If you were faced with delivering content on BD and material which the mainstream broadcasters would accept internationally (ie, US and EU), what video output would you select?

Mt thanks is advance.

I would that the 720p must be the most developed one, so I would say that you should take it. But on mobile phone, I don't know at all...

720p or 1080i. Both of these formats are available in cameras and as a standard by which video editing can occur. If you are mastering films, then perhaps 1080p is the best master rate to work at, then compression to more common formats can be handled by video encoders.

1080i, 720p, 480i, etc.

My golden rule with video editing is to start with the absolute highest quality I can, do all my editing at that level, then create digital masters as that level. At the end - compress, scale down, lower the quality.

Ofcourse. The last thing you want to do is upconvert the picture so...

Many thanks for this advice, most helpful and the references to the 720p fits with the EBU D97 regs we were given.

One suppilmentary question. On the Blu-ray FAQ page, references only mention 24, 30, 60. Because European electrics are 50 hz, the EBU stipulate 720p50 - the D97 goal is 1080p50 eventually. These rates are required if live action recordings are not to be affected by light flicker, a real problem when filming 25fps in the US, or 30fps location recording in Europe.

So is the absence of these european frame rates relevant? Does it mean that Blu-ray will only support the 24,30 and 50 frame rates? Or is this just an oversight on the webmasters when compiling the data page? I hope it is the late as hoe would anyone record EBU HDTV to Blu-ray?

We are currently testing 720p50 and 1080p25 ... all we need now is the monitors to arrive so we can really see the results.

Thanks again for the advice.
