Re: [Avid-L2] Re: Up-Rez HD to 4K and film scanning resolution

Scanning resolution is a big deal, especially for grainy film. Look here to see some grainy Super-8 scanned at three resolutions — up to 2.8K — and see what is gained. It goes against the conventional wisdom that smaller formats don't benefit from higher scanning resolution.

Hi,

I've been scanning some old slides at 5,000 dpi on a Nikon cool scan. I think that when I'm scanning film from the 40's and 50's sharpness is limited by grain. Wouldn't grain size be a limiting factor? In any case, seems to me, up-rezing after the scan should not yield any additional details. The film should have been scanned to yield 4K frames.

Best Wishes,

Paul

Right. I understand all this. The real question is more-or-less two-fold. 1) Does 4K mine out more detail from 16mm neg, and 2) what kind of hit does HD res material take when being upscaled to a 4K master?

Thanks!

The slower the stock generally the finer the grain size. I agree that generally 2K/1080 is more than sufficient for 16mm.
Even some modern 35mm films went through a 2K DI process.

The 16 mm movies i've restored in the past showed huge amount of grain in the SD telecine.
Granted, those were dated between 1911 and app. 1970, and mostly shot on cheap / available stock.

Most 16MM would be showing the grain even at 2K.

I'd agree. Generally 16mm is good to 2K and HD isn't much under that. But a good Telecine to 4K will eak out more for sure.
If you want to get the most then recan the 16mm direct to 4K
