garden at Oakwood Grange, Roundhay on 14 October 1888. The NMPFT animation lasts two seconds at 24fps (frames per second), meaning the original footage is playing at 10fps. In this version, the action is speeded up - the original footage was probably shot at 7fps. Traffic Crossing Leeds Bridge (Single-Lens Camera MkII) Louis Le Prince filmed traffic crossing Leeds Bridge from Hicks the Ironmongers at the following coordinates: . The earliest copy belongs to the 1923 NMPFT inventory (frames 118–120 and 122–124), though this longer sequence comes from the 1931 inventory (frames 110–129). According to Adolphe Le Prince who assisted his father when this film was shot in late October 1888, it was taken at 20fps. However, the digitally stabilised sequence produced by the NMPFT lasts two seconds, meaning the footage is playing here at 10fps. As with the Roundhay Garden sequence, its appearance is sped up, suggesting the original footage was probably shot at 7fps. This would fit with what we know of the projection experiments, where James Longley reported a top speed of 7fps. Accordion Player (Single-Lens Camera MkII) The last remaining film of Le Prince's single-lens camera is a sequence of frames of Adolphe Le Prince playing a diatonic button accordion. It was recorded on the steps of the house of Joseph Whitley, Louis's father-in-law. The recording date may be the same as Roundhay Garden as the camera is in a similar position and Adolphe is dressed the same. The NMPFT has not remastered this film. An amateur animation of the first 17 frames is .
