I would think it can only be as good as the film thats being redone.

Not true, the old, really old 4:3 movies from the early days, were not hd. Because they weren't widescreen.

Almost ALL theatrical movies can be downgraded to HD.

1.37:1 movies can be cropped to 16x9 (1.78:1) and still have sufficient resolution to be downgraded to HD.

Some classic movies 1.37:1 were cropped far more severely and re-released:

Fantasia (1940) was cropped to 2.55:1 and released as a CinemaScope feature in 1956, complete with 4-channel stereo soundtrack.

Gone With the Wind (1939) was cropped to an AR of more than 2:1 (I forget the actual AR) in 1968 and exhibited at premium prices.

Others were cropped to 1.85:1

That almost eliminates all movies if you put the widescreen requirements of the HDTV ATSC standard of 16:9 widescreen. On that basis any movie that was not 1.78:1 would not be HD.

I think the spirit of the question was if there is enough resolution in the old movies to scan to HD resolutions and the answer is yes and then some. If it is fair to call 2.35:1 movies HD, it would be fair to call 1.33 movies HD, the black bars would just be in a different location. CEA, after all, only requires the number of lines to be at least 720 for the display to be considered HD, no matter how many pixels wide it is.

I think in the future you will see some of the classics offered in HD in their original AR of 1.33:1.

Default How many Pixels are there in a frame of 35mm film?

The very short answer is that there are around 20 million "quality" pixels in a top-quality 35mm shot.

What this means is that a 5300 x 4000 digital camera would produce a shot equivalent to a scan from a quality 35mm camera


How many pixels in a frame of 35mm film?

A 1920x1080 HD signal is only 2 million.

Should be able to salvage enough resolution on old film to make a decent picture.

Default film

The only problem would be the quality of the original film. Some older movies may have poorly kept master copies, with faded colors, grain/noise that wasn't there in the original. I would imagine some movies would need to go through a restoration process and cleaned up before transfering to digital.

By equivalent pixels are we talking here about the smallest discernable detail being equivalent to one pixel? Because if a generally unfocused, ie poor, master is scanned into high resolution it will still look poor.
