Abstract
A film projection system for use with a continuous film motion telecine machine includes a film guide (17, 18) which guides the film (1) past a gate (13). The film guides (17, 18) form part of two endless bands (14, 15). The parts of the bands (14, 15) in contact with the film (1) are arranged to move at substantially the same velocity as the film and there is provided means (19, 20) for varying the spacing between the bands.
