8mm Film is actually based on 16mm Film, with twice as many perforations along each edge. Only 1/2 of the width of the film is exposed, and once the film reaches the end of the takeup reel, it is flipped to allow access to the other half of the film. 8mm is normally recorded at 16 frames per second.

Developed by the Eastman Kodak company during the Great Depression, it was released to the market in 1932 as a less expensive option to 16mm film for home movies

Common mold, dirt, and dust can result in a dull or dim image, and poor audio. Over time, all Acetate film can deteriorate commonly called 'Vinegar Syndrome'. This is commonly noted by a strong smell of vinegar, and the film itself eventually shrinking, becoming brittle, and separating it's layers. Once Vinegar Syndrome begins, there is no repair. It is very important to digitize film before this happens.

Super 8 Film was similar to 8mm, but came in cartridge form, making it easier for amateur film makers to use.

Super 8 film was released in 1965. It featured an improved image quality. Unfortunately, some cameras for Super 8 featured cheaper plastic film gates and pressure plates which was less reliable for keeping the image in focus.

Just like 8mm and 16mm film, Super 8 is vulnerable to dust, mold, and dirt causing dull or dim images. Undeveloped film cartridges can help protect against the dust/dirt. Super 8 is also vulnerable to 'Vinegar Syndrome', and should be converted to digital to prevent the loss of the contents.

16mm Film itself looks similar to 8mm film, but the frames are larger (hence 16mm vs 8mm) and was available in both silent and with audio track.

Introduced by Eastman Kodak in 1923, 16mm film was marketed as an inexpensive alternative for amateur film makers. In the 1930s, 16mm film began to make inroads to education. Adding optical sound tracks, and the addition of Kodachrome in 1935, gave an enormous boost to the market. Extensive use in WW2 led to a huge expansion in professional filmmaking post-war. The advent of television boosted the use of 16mm film, due to cost and portability advantages over 35mm film.

Just like 8mm and Super 8, the same things affect 16mm film. Dust, dirt, and mold can cause dull/dim video and audio. 16mm is also susceptible to 'Vinegar Syndrome', and like all film it should be digitized to preserve it.
