The Archival Bookings Officer will give as much information as possible about the condition of prints. If there are defects or damage printed through from the original or if a print is being shown by necessity at the wrong speed you should ensure that this is explained to the audience either in the programme notes or verbally where the screening is being introduced. Silent film should be run at the correct speed.
Some projectors have infinitely variable projector speeds others have a few pre-set speeds.
In the latter case the nearest of the pre-set speeds would be acceptable, say 18 frames per second for a film shot at 16 frames per second. Bookings staff are happy to advise on correct running speeds. Film should be shown in the correct ratio and with the right aperture plates, particularly for silent film. In the case of accidental damage to a print projectionists should not attempt to repair the print and in no circumstances remove any frames. A report should be sent from the projectionist to the Archival Bookings Officer so a correct assessment of damage can be made.
