Re: [Avid-L2] Re: Up-Rez HD to 4K - dynamic range

 

David:


We do lots and lots of B&W negative — lots of nitrate, even.  

Let me know if I can help.

Best,

Jeff

Well, in my particular case, I have 16mm black and white neg. It's well-shot. But with this show, it's growing more likely that I will need to re-transfer this neg directly to 4K. Is the Kinetta adept at monochromatic material (and, of course, I can't think of any reason why it shouldn't be, right?)?

There are many telecine (like the Spirit) that were designed for modern color negative stocks, and don't have the dynamic range to capture everything in a contrasty reversal original or print — sometimes they can fake this by doing extensive shot-by-shot grading during the transfer, sometimes they sacrifice either shadow detail or highlights.


We have worked very hard to make sure we can capture everything on the most contrasty film without compromise — as a result Kinetta owners scan a lot of reversal originals and prints.

Go to kinetta.com and look at the RANGE page — download some of the linked TIFFs to see raw scans at full res with the full dynamic range of what is on the film:


We scan at resolutions up to 5K.  There are now Kinettas on 4 continents….

OK, I know, shameless self promotion!

I worked on a show that took 16mm negative and telecined to HD and it was a joy to work with.  This was footage from '63.  I'm not speaking to detail but the ability to dig things out of the shadows etc...  4K probably won't do much for the dynamic range but I wouldn't think it would hurt.

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
