The first table shows how the same film looks using our 4 different processes. You can see that the difference can be significant for our Gaithersburg customers.

The second table presents a case for scanning 8mm and Super 8 film at 2K resolution. In the past year we have done 20 comparisons. Contrary to popular belief, we do see a noticeable difference in quality between our Pro HD and Pro 2K process on 8mm and Super 8 film.

In general it is recommended that you scan at or above the resolution of the film. For 8mm and Super 8 that means scanning at HD or 2K.

8mm And Super 8 Film Gaithersburg


SD Scan

  • This SD scan was performed with a SD frame by frame machine. The film is ran through a projector and captured using a camcorder.
  • If you compare this to the HD or Pro 2K scan you can see that this SD scan almost looks blurry.
  • In addition, you can see the blue color shift. This is very common on both 8mm and Super 8 film.


Pro HD Scan


Pro 2K Scan

  • This Pro 2K Scan (1556 lines) was performed with a professional 2K Datacine machine.
  • This example also includes our optional color correction restoration.
  • Compared to the Pro HD scan you can see more details and better color and skin tone.


Pro 4K Scan

  • This Pro 4K Scan (3112 lines) was performed with a professional 4K Datacine machine.
  • This example also includes our optional color correction restoration.
  • Most 8mm and Super 8 film will not benefit from a 4K scan. But you can go out to a 4K format like 4K-ProRes. This would allow you to create formats for your 4K/UHD TV.

 

Film Resolution


8mm 2K Scan

Resolution of Film


  • Determining resolution of film can be a very complicated and controversial task involving many variables.
  • The image to the left is a 2K scan (1556 lines from top to bottom) of 8mm film
  • At full frame it looks nice and clear and you don't see a lot of film grain or digital pixilation.


8mm 2K Scan

Film Grain

  • As you zoom in you can start to see the film grain (looks like little dots or bumps).
  • We've highlighted the smallest feature which is on the tip of this person's nose. This is about the size of the film grain.
  • Film grain is laid out in a random pattern.
  • Film grain is not laid out in a nice, neat pattern like digital pixels in a digital image.


8mm 2K Scan

Film Grain vs Digital Pixel

  • Here we are zoomed in enough on the 2K scanned image that you can see the digital pixels.
  • The red highlighted area is the smallest feature size which is about 1 grain of film.
  • In order to achieve a digital image as good as the film you would need to scan the film at 1/2 the size of the film grain or smaller. Here, the 2K scan is just enough to meet this requirement.

 

So, for example, if you are looking for the best quality DVD, scan your 8mm or Super 8 at HD. If you are looking to go to BluRay then scan your 8mm or Super 8 at 2K.

Gaithersburg Fun Facts: In 1899 the Gaithersburg Latitude Observatory was built and along with five others like it around the world, was used to gather information for measuring the earth's polar motion and determining its size, shape, and physical properties. The year 1961 saw the move of the National Bureau of Standards (now known as the National Institute of Standards and Technology) into Gaithersburg, creating a complex which maintains standards for scientific research and houses the standard meter and kilogram to which all others are compared for accuracy. Other science-related firms soon followed suit, giving the city the nickname of "Science Capital of the United States". Today a suburb of Washington, D.C., Gaithersburg's major economic activities of biotechnology, telecommunications, and software development are largely related to Federal Government contracts.

Maryland Fun Facts: Annapolis, the state capital, is also home to the United States Naval Academy. Maryland is the leading producer of blue crabs and is renowned for its crab cakes. One of the original 13 colonies, Maryland lies at the center of the Eastern Seaboard, amid the great commercial and population complex that stretches from Maine to Virginia. Its small size belies the great diversity of its landscapes and ways of life that they foster, from the low-lying and water-oriented Eastern Shore and Chesapeake Bay area, through the metropolitan Baltimore, its largest city, to the forested Appalachian foothills and mountains of its western reaches.
