This format became popular for home movies due to its affordability and ease of use. The film is typically loaded into a cartridge, allowing for simple operation in 8mm cameras. Regular 8mm film has a frame size of 4.22mm x 3.18mm, which provides a lower resolution compared to modern digital formats. Despite its limitations, it remains cherished by enthusiasts for its nostalgic qualities.
