I have 2000 feet of 9.5mm film on five reels, taken in the 1940s and 1950s. Movies taken by a deceased friend, of family and wild places in Tasmania, parts of which will end up on Blu-ray. I want it scanned at 2K on a high-end machine such as a Lasergraphics ScanStation, MWA FlashTransfer Choice, or similar.
As far as I am aware:
- no company in Australia has such machines.
- Images4life.uk has a FlashTransfer, but the cost increases by 50% to convert from DPX to ProRes 4444, and another 50% if I ask for transfer at a slower scan-rate (10 fps instead of 15 fps, recommended for improved quality)
- videopro.dk have the ScanStation and a lower resolution model of the FlashTransfer, but from my experience there are language – and other – difficulties.
I have been unable to track down anyone else who can do this work. This leads to several questions. Below, when I mention scan-rate, I mean the number of frames scanned per second.
Does anyone know of a company, anywhere in the world, that can scan 9.5mm films using a high-end machine? i.e. something better than a Retroscan. The company must be happy to deal with a home enthusiast. Some aren't.
Exposure vs Scan-Rate
Is exposure time when scanning, linearly dependent on scan-rate? i.e. double the scan-rate and the exposure time halves?
Or does the exposure time vary non-linearly with scan-rate? If so, why?
How does varying the scan-rate effect the quality of the scan? For instance, does scan quality inherently go up as scan-rate goes down? What factors are involved?
For a 2K scan of an 8mm film, what would be typical exposure times for a certain scan-rate?
The films are mostly amateur B&W. During editing in Premiere, all the scans will need a goodly amount of contrast correction, and a small number will require significant boosting in the shadows.
Assuming that shadow detail is actually on the film and can be captured by the scanner, does 4444 holds extra information in a form that would give obviously better results than 422 HQ when grayscale shadows are boosted significantly in Premiere?
Personally, I doubt that 4444 is worth the extra file size for these films. But I thought I'd ask, just in case.
