Talk:The Haverstraw Tunnel

"Running time" estimate
In the infobox I wrote that the film "Running time" was 1538 frames, based on data from IMDb the film print length was 104.55 meters at 68 mm/frame. For early silent films with no calibrated synchronization scheme the playback runtime could vary considerably, but a runtime time estimate would also be most welcome. 69.115.42.244 (talk) 00:55, 7 December 2011 (UTC)
 * This reference at silentera.com mentions a print length of "54 feet". If we can assume that the 54 foot prints were at 35 mm frame size then applying the ratio of 68/35*54 feet = 104.91 feet (not converted to meters).  Hence it may be the case that there were fewer than 1538 frames. 69.115.42.244 (talk) 02:03, 8 December 2011 (UTC)
 * Extant copies of the film (on digital video) run right at 1 minute.
 * Library of Congress Paper Print converted to 16mm film (27 feet in length) produced in 1955. That length converts to 1,080 frames. Transfer at 18 frames per second, yields a running time of 60 seconds.
 * British Film Institute National Archive has 11 fragments in original 68mm Biograph format. The 68mm film restored in 35mm film is 96 feet long (approximately 1,536 frames).
 * I put an authorized MP4 from BFI online in 2020. The video runs 60 seconds.

 * The Biograph company production records list two 35mm lengths for The Haverstraw Tunnel film. 343 feet (5,488 frames) and 59 feet (= 944 frames = 52 seconds at 18 fps). It's not clear what these numbers refer to in the AMB log. Was 343 feet the length of all the footage shot?
 * In 1906, a Hale's Tours sales catalog listed its 35mm copy of Biograph's Haverstraw film as 200 feet, made from an "old and defective negative."
 * 944 frames would have been appropriate for Mutoscope machine flip-cards. I've seen no references to Haverstraw on mutoscope cards.
 * The 1 minute running time was rather typical for a subject as presented by the American Biograph theatrical projection. In 1897, Biograph projectors were motorized (not hand-cranked) and ran 68mm celluloid prints. Projection and camera speeds during 1896-1902 were around 30 frames per second.
 * I published 3 blog posts about this. See wp.nyu.edu/orphanfilm/?s=haverstraw orphans (talk) 23:02, 19 June 2023 (UTC)
