For most of the 20th century, amateur films were shot in black-and-white and without sound. This gradually changed from the 1960s and 1970s onwards, when new possibilities for making colour and sound films emerged.
Colour film
While both colour photography and filmmaking were available for amateurs in the early 1900s, they were rarely used because of their high cost and complicated production processes. Black-and-white photography and film persisted as the norm well into the 1960s.
Technically, colour photography and film involved either an additive or subtractive process. In the additive process, colour was reproduced by adding several colour filters to both the recorded and projected images. In the subtractive process, introduced in the 1930s, colours were not added but subtracted from light by using cyan, magenta and yellow dyes or pigments.

Kodacolor was one of the first colour films for amateur users, introduced by Kodak as a 16mm filmstock in 1928. It used an additive colour process, unlike the Kodachrome film introduced in 1935, which used a subtractive colour process. Even though Kodachrome was first released for 16mm film, it soon became available for 8mm film and 35mm slide photography as well. Other early colour films used by amateurs include the Agfacolor, Pathécolor and Fujichrome direct reversal films.
In 1961, Kodak introduced Kodachrome II: an improved version of the earlier Kodachrome colour film. It featured a higher film speed and improved image quality. Kodachrome II, used later also in Super 8 filmmaking, developed into one of the most popular colour films of the 20th century.

With Super 8 film, the recording of colour films eventually became the norm. Super 8 film cartridges were initially even available in colour film only. Also, the arrival of colour television in 1967 and further advances in colour amateur photography contributed to the transition from black-and-white to colour in amateur film recording and screening practices.
Colour filmmaking resulted in new amateur recording practices and genres, such as the increased recording of flowers, gardens and other colourful objects and sceneries. The holiday film, a popular home movie genre, began to be increasingly shot in colour.
Sound film
As with the making of colour films, amateurs were already making films with sound in the early 20th century.
The first amateur sound film systems specifically designed for home use emerged in the 1920s and 1930s, for example the DeVry Cine-Ton projector (1928), Western Electronic Sound-on-Disc recording system (1930) and the RCA-Victor 16mm sound-on-film camera (1935). The RCA-Victor 16mm optical sound recording system was made to record the voice of the person behind the camera in particular. (See and hear an American 16mm sound home movie from 1936-1937 here.)
These early electrical and optical sound film systems were rather expensive, complicated to use, and technologically limited. Only a few amateur filmmakers experimented with making sound films during these years.
With the development of magnetic sound recording technologies in the 1950s and 1960s, it became easier for amateurs to make sound films. The first magnetic sound film systems allowed for adding a magnetic stripe to the 16mm film in post-production, so after the film was recorded, developed and edited.

The release of various Super 8 sound film cameras boosted the practice of recording sound films even further. Kodak's Ektasound recording and synchronisation system, introduced in 1973, allowed amateurs to make direct sound recordings by means of a so-called "pre-striped" Super 8 film: a small piece of magnetic stripe attached to the non-perforated side of the film.

Despite the new opportunities for amateurs and families to create their own sound films, most amateur films and home movies remained silent until the late 1970s and 1980s, when consumer video technologies expanded the possibilities for synchronous recording and screening of sounds and moving images.
