“Produced by Louis Aimé Augustin Le Prince at Roundhay House, Leeds, UK, some time before October of 1888.”
I found this very interesting. I’ve mirrored the movie because the NMPFT site was running slow.
More on Le Prince and evidence that this really is the earliest single-camera motion picture ever captured:
Roundhay Garden Scene, 1888
Photographic copy of paper prints from a film taken in the garden of the Whitley family house in Oakwood Grange Road, Roundhay, a suburb of Leeds, Yorkshire, Great Britain. Le Prince’s son, Adolphe, who appears in this picture, stated that it was shot in early October 1888 (he suggests 14October) as it shows Mrs Sarah Whitley, Le Prince’s mother-in-law, who died on 24 October that year. The other subjects are Joseph Whitley and Miss Harriet Hartley. They are plainly having fun walking round in circles, keeping within the area framed by the camera.
