The AP Film Dubbing Suite
When the BBC decided in 1948 to make its own newsreel for the Television Service it was realised that an in-house facility would be advantageous. Until the AP Dubbing Theatre came into service at the end of 1949 the Television Newsreel (TNR) was recorded and dubbed in the Re-recording Theatre of RCA situated in The Tower, at Hammersmith Broadway.
N.F.Chapman, of Planning and Installation Dept (P&ID), BBC Engineering Division, published a technical description of the new facilities at AP in ???
A FILM DUBBING AND REVIEW SUITE
A Film Production Unit is an essential part of a Television Service. One of the most important functions of the B.B.C. Film Unit is the regular production of newsreels, but its activities cover a wide field and include the production of film sequences for television plays and special documentary and demonstration films.
In addition, the unit is responsible for editing “Telefilms” and for checking and preparing such commercial films as can be obtained for television. To enable these activities to be carried out efficiently, and to ensure that the productions shall attain a high standard of technical excellence, a comprehensive scheme for equipping the Film Unit with apparatus of the latest design and best obtainable performance has been prepared. This scheme is now well advanced, the first project to be completed being the film dubbing and review suite at Alexandra Palace.
Film dubbing and review theatres are, of course, used in commercial film production, and the arrangements at Alexandra Palace conform in fair degree to standard modern practice. Several features are unusual, however, and as the suite is probably one of the first to be built specifically for television film production it is hoped that a description of it will be of interest, especially to those engaged in television who are unfamiliar with modern film technique.
THE PURPOSE OF THE SUITE
Film Dubbing Section
In addition, the film dubbing section is equipped for the carrying out of several other operations. It can be used for reviewing 16mm or 35mm films with combined or separate sound tracks, for disk to film or film to film re-recording, and for recording from any source on 35mm film running in synchronism, if necessary, with a film picture camera in the dubbing theatre or in one of the studios. It can also be used for post-synchronisation, i.e. the addition of exactly synchronised speech to a previously prepared silent film sequence, and for the addition of live commentary and non-synchronous music and effects to a silent film during transmission. Several of these operations can, as a result of the way in which the dubbing section has been designed, be carried on simultaneously.

DESIGN OF THE SUITE
As has already been mentioned, film dubbing suites are a common feature of all film production centres, and the question arises, what are the particular requirements of a suite built specifically for television film production? In the present state of the art these requirements may be summarised as follows:
