The Difference Between 8mm and Super 8

The Difference a Sprocket Makes

To the naked eye the difference between 8 mm film and Super 8 mm are simply that the sprocket on Super 8 are smaller and square rather than rectangular. A common misconception is that Super 8 is actually a different size film than 8mm but this isn’t true; both film formats are both 8mm in width. By shrinking the sprocket size Super 8 film is able to accommodate a larger frame size within the same 8mm film width. This difference may seem like a small change but the sprocket size of 8mm film was limiting the possibilities for innovation.

Frame Size Improvements

The image quality of any given film format is determined primarily by the size of the film frame. The larger the frame the more information each frame can hold. Standard 8mm film could only accommodate a 4.5mm by 3.3mm frame because of the room taken up by the sprockets. Super 8 improved on the frame size by a great deal within the same overall film size. The super 8 frame size grew to 5.79mm by 4.01 which is a 26% increase in image area.

Super 8 Merges Audio With Video

In addition, Super 8 film incorporated a magnetic sound strip that could record audio similar to the way a tape machine does. This advancement made the Super 8 film an immediate favorite for family and hobbyists for many decades. Recovering the Super 8 audio is a tricky process that involves taking photos of the sound waves recorded to the magnetic strip and converting those waves into actual sound files. This technology is still very early in its development. Even after VHS tape cassettes had taken over the entry level camera market in the 80’s people still continued to use Super 8 film for the unique character that was innate in the film format.

Film Degradation – Vinegar Syndrome

By | 16mm Film, 8mm Film, FIlm Scanning | No Comments

Better to Degrade than to Ignite

The film that our home videos are stored on is almost always cellulose based Safety Film. This is the non flammable film stock that was created after too many Nitrate based film reels caught on fire. The problem with the Cellulose Acetate Plastic is that is not the most stable material to store images on and over time it falls victim to Acetate Film Base Degradation. This process is known as Vinegar Syndrome because of the acetic acid (vinegar) that is created when this degradation occurs.

Difficulties Converting

The unfriendly smell really wouldn’t be so bad if it didn’t also destroy precious memories and cinematic history. The physical state of the film changes so much that it can become impossible for the film to pass through any video equipment without breaking. This is largely due to shrinkage of the film in length and width and the loss of flexibility. Once the film is bent it usually wants to buckle or break due to a curvature along the width of the film. If an image can be pulled from the film it could likely be shrunken down, partially out of focus and erratically shaky.

Preserve and Protect

This process takes a long time to occur and can be postponed with cool, dry storage conditions. Regions of the world that have higher temperatures and humidity have a much greater problem with vinegar syndrome than others. Once this process has been detected it is best to get the film to a preservationist as soon as possible to make sure that the film can be digitized before the condition worsens.

Our Film Scanning Process

Family History First 

The biggest difference between Roots Family History and every other company that can scan your film is that we are a Family History Company and not a Scanning Company. This means that we are invested in helping you discover your family history. Our process of scanning film incorporates organizational skills and the highest quality standards to ensure that your memories are crystal clear and easily accessible.

Capturing Every Frame

When scanning home movies we are usually dealing with film that was shot by amateur videographers and often times the focus or exposure may not be quite right. We make sure that we compensate for these factors as best we can when scanning the film. This means we take extra time with each roll to find what the optimum exposure is. Many film scanning methods can unintentionally crop the frame of the film which means that you get back a video that isn’t showing the full imagery. Our process eliminates that problem so you always see the full picture in high resolution. 

Organizing Memories

In the digital age we all know what it feels like to be overwhelmed with digital clutter. Unorganized files take up space and become more trouble than they are worth. We carefully follow each reel from pickup to drop off and make sure that any information that is attached to that reel will be attached to the file that we hand back to you. We create a new file for every film reel so your digital organization can match the organization of your film. 

What is Frame by Frame Film Scanning?

Many Frames | One Reel

Sometimes it’s easy to forget that every video or movie we’ve watched is actually a series of images that are flashed before us at high speeds. It takes over a thousand frames each minute to create the illusion of movement and make these still images appear as a video. When digitizing a reel of film the only way to truly capture all the quality of this analog media is to scan each and every frame. This is the process of Frame by Frame scanning.

Improper Film Scanning

The inferior way of scanning film is to use an old projector to display the video on a wall and film the wall with a digital camera. The resulting video is likely to have improper exposure, unwanted cropping and a number of other imperfections. This wall filming method is called Telecine and it is the cheapest way to digitize film but will never recreate the quality and liveliness that a film reel has.

Capturing Every Single Frame

Frame by frame scanning requires a state of the art machine that can locate and capture a photo of every frame on a reel of film. This ensures no detail will be lost between frames and all the detail of every image will be the highest possible quality. Taking separate images of every frame requires more time for the film to be scanned but eliminates focusing and cropping errors that occur with other methods. The series of images that is created when a reel is scanned is then imported into a video editing program where it is made into a video.
