DIY 8mm Scanner

I developed my project to scan a large number of regular 8mm normal film. 8mm material of that time, i.e. the 60s of the last century, was very coarse-grained, because it was made from 16mm material with added perforations. The mechanics of the cameras from the 60s were not nearly as good as the later super-8. This resulted in more or less jitter. The cameras of that time had no automatic focus and aperture. Because of grain and limted sharpness, I scanned in 2K. Lightbarriers where added to the scanner, to watch film end and breaks. So the scanner could run unattended. I recorded in JPEG format, which results in smaller amount of data. For film resolution and quality, this is perfectly adequate. Tests with RAW Format have shown, that of course the amount of data is considerably larger, but the quality is not necessarily better, and the whole workflow is much more difficult. I did the postprocessing in two stages. I started with DaVinci resolve for stabilization and cropping to the 4:3 format. Resolve Fusion has a very good stabilization. I always tried to stabilize to content, as perforation and image borders are not stable enough. The films vary greatly in brightness so I took three pictures per picture with the bracket method, i.e. i in a normal exposure and plus and a minus one. This allows me to select the best exposure in the post-process. Degrain and despeckle has been done with NEAT-plugin in Sony Vegas. For a compromise grain vs. sharpness, I opted mainly for shrapness. Output was rendered with 32 fps = 2x16 from the original, letting SV resample for missing images. Experiments with DAIN where not successful, because of the grainy, unsharp source material, which led to severe artifacts.
