Default HD movies
I wonder how they make an old movie look incredibly sharp in HD.. Is there any good explanation to that? I mean, how is it possible to improve something so old that drastically?

Film has a much higher resolution than SD TV.

No, you're all wrong. Dead wrong.

They do scene-for-scene recreations of old movies with amazing CGI wizardry. When you're watching A Christmas Carol in HD, the part where Alistair Sim stands on his head is actually a multi-billion texel model, incorporating a complex series of algorithmic ragdoll equations, coupled with real-time DX10 physics, giving the impression that Mr Scrooge is close to losing his balance.

It's amazing what computers can do these days, I always wondered how they made HD out of old movies. [yes] Can't wait to look like the clever one down the pub now. [thumbup]

For the longest time I totally thought that was how they did it. [rofl]

No but essentially a vast majority of motion pictures are shot on 35mm film which as others have said is significantly higher resolution (or capable of capturing more detail as it isn't digital so there isn't a direct pixel rating). For quite some time now movies are shot on film, the film is processed, and then it put through a process called telecine which captures the movie on video so that it can be edited in non-linear editing software. Now film scans are much more prevalent because of the much higher resolution that can be achieved. The two types of film scans are 2K which is 2048×1536 pixels and 4K is 4096×3072 pixels.

After that process the film is then color corrected before going to the editor. Once the film is cut it is then printed back to film for distribution unless it is going to theaters equipped with digital projectors. (In that case the film would be on a HDD or other very high capacity media.) When they are scheduled to hit the consumer market on DVD, HD DVD, and Blu-ray the films are handed off to their respective studio to have any optimizations necessary made like color adjustments or overall remastering. Once all is said and done they are pressed and you can have movies like Caddyshack which was shot in 1980 in HD glory.

Exactly right! Not only that, but the tooth fairy is real!

How do they manage to get a 5.1 or 6.1 surround audio out of the old movies then ?

That's fake and simulated.


As long as the film is preserved correctly, though, a 20 year old film as the potential to look as good as a film made last year.

It is all dependent upon the year it was made and the studio where the re-recording was done. The basics in a films audio is dialog, music, effects, and backgrounds and they are all on separate tracks. This is required not only to allow flexability and changes to the mix but because of international distribution where another language might have to be dubbed. Essentially all of the elements are then pulled into a session and the film is upmixed to discrete sound formats. Dialog will be almost always bussed to the center channel, the effects for the most part will be an LCR bus (Left Center and Right path) with some spotted effects as well as backgrounds bussed to the RS and LS. Depending on the sound supervisor's preference he might want to wet the music with some reverb and bus the music to the surrounds as well.

Basically each studio and sound supervisor have different preferences in regards to aesthetics but they are all essentially taking those elements and creating a discrete multichannel mix.

It's also worth noting that Dolby Stereo, introduced way back in 1975 could essentially be used to make a surround soundtrack. Though its discrete channels were only FL and FR, it did have a centre and rear mono track matrixed into those two front channels.

you guys should check out some of the oldies shot with 70mm film... lawrence of arabia for example looks amazing for such an old movie... the most impressive was 'the searchers' from 1956 (i dont know if its 70mm though)
