How are originally non-hd movies re-released in fullhd quality?

Question

how are movies that were made from a pre fullhd era back in the 1980s or earlier, re-released today as fullhd blu-ray movies? movies such as blade runner, enter the dragon(bruce lee), bullit, deliverance just to name a few, which were originally filmed in non fullhd(1920x1080) are now released on blu-ray disc as fullhd. are these movies really in fullhd or just the original format on a blu-ray disc instead of a video cassette or dvd.

Answer 1

There is no digital (and there may never be) system out there today that can rival film or vinal audio. Digitizing the media may use shorter stair steps as the art progresses, but it is still a stair step and not a sine wave. The same holds true for 35mm film, not to mention the larger movie formats.

Answer 2

"HT GURU" is all over it!

Fa sho!

Answer 3

I am not 100% percent sure but I know that the original film is of much higher quality than a regular DVD. So they must use the original film and convert it into high-def.

Answer 4

the exact process i really dont know but

Almost all movies - including most of those made right now - are shot on 35mm film. Film isn't digital so technically it doesn't have a "resolution" at all. But in theory you need about "K resolution (4096×3072) to get all the image information off a clean 35mm print. Blu-ray is 1920x1080, or about 2K (which would be 2048 x whatever).

So any movie shot on 35mm can, in theory, look better on Blu-ray than on DVD, no matter how old it is.

How good it acutally looks depends on how well-preserved the film they have to work with is and how much effort is invested in cleaning it up and remastering it for Blu-ray.

Answer 5

if i remember right movies where shot on either 60mm or 80mm film. never 35mm. how they do it is scan the film into a computer. using a refining program they clean out the fuzz and distortion. they use another program to upscale the clarity of the picture. then remix the sound into 5.1 or higher audio. one of the reasons the format is so expensive is because of the work it takes to clean it up.
