Movie and Video records of family history

Movie Film formats:

35mm--usually used for professional/Hollywood movies.

16mm--first commercially successful home movies format. Invented by Kodak.

8mm or "Standard 8"-- introduced by Kodak during the Great Depression as a cheeper alternative to 16mm. The original 8mm used 16mm film, which was run down one half, then flipped over and the other half was filmed. During processing, the film was split and spliced together. 8mm was really successful.
