    Not sure if this is the right forum for this...apologies if it isn't...

    Can anyone tell me how an HD programme is originally filmed? What I mean is, for example, does a film have to filmed in HD to be broadcast in HD? I'm assuming not as there are many 'old' films that you can view on Sky in HD or buy on HD DVD or BD that were orginally filmed before HD was around.

    Is there any difference in definition between a film that wasn't originally filmed in HD and one that was?

    Thanks

    I think the answer is that normal "film" has an effective resolution that is much higher than HD, so therefore it does not need to be filmed in HD to enable a HD master to be created. This would explain why the likes of Kubricks 2001 have such as stunning HD transfer, despite being 40 years old.

    Typical 35mm cinema film stock has an effective horiaontal resolution of between 3000 to 4000 lines of resolution.

    Most are closer to 3 than 4!
